ActiveMQ 5.x

Since Camel 1.0

Both producer and consumer are supported

The ActiveMQ component is an extension to the JMS component and has been pre-configured for using Apache ActiveMQ 5.x (not Artemis). Users of Apache ActiveMQ Artemis should use the JMS component.

The camel-activemq component is best intended for ActiveMQ 5.x classic brokers. If you use ActiveMQ 6.x brokers, then use the camel-activemq6 component instead.

More documentation

See the JMS component for more documentation and examples

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-activemq</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

URI format

activemq:[queue:|topic:]destinationName[?options]

Where destinationName is a JMS queue or topic name. By default, the destinationName is interpreted as a queue name. For example, to connect to the queue, foo use:

activemq:foo

Configuring Options

Camel components are configured on two separate levels:

  • component level

  • endpoint level

Configuring Component Options

At the component level, you set general and shared configurations that are, then, inherited by the endpoints. It is the highest configuration level.

For example, a component may have security settings, credentials for authentication, urls for network connection and so forth.

Some components only have a few options, and others may have many. Because components typically have pre-configured defaults that are commonly used, then you may often only need to configure a few options on a component; or none at all.

You can configure components using:

  • the Component DSL.

  • in a configuration file (application.properties, *.yaml files, etc).

  • directly in the Java code.

Configuring Endpoint Options

You usually spend more time setting up endpoints because they have many options. These options help you customize what you want the endpoint to do. The options are also categorized into whether the endpoint is used as a consumer (from), as a producer (to), or both.

Configuring endpoints is most often done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL and DataFormat DSL as a type safe way of configuring endpoints and data formats in Java.

A good practice when configuring options is to use Property Placeholders.

Property placeholders provide a few benefits:

  • They help prevent using hardcoded urls, port numbers, sensitive information, and other settings.

  • They allow externalizing the configuration from the code.

  • They help the code to become more flexible and reusable.

The following two sections list all the options, firstly for the component followed by the endpoint.

Component Options

The ActiveMQ 5.x component supports 111 options, which are listed below.

Name Description Default Type

brokerURL (common)

Sets the broker URL to use to connect to ActiveMQ. If none configured then localhost:61616 is used by default (however can be overridden by configuration from environment variables).

String

clientId (common)

Sets the JMS client ID to use. Note that this value, if specified, must be unique and can only be used by a single JMS connection instance. It is typically only required for durable topic subscriptions with JMS 1.1.

String

connectionFactory (common)

The connection factory to be use. A connection factory must be configured either on the component or endpoint.

ConnectionFactory

disableReplyTo (common)

Specifies whether Camel ignores the JMSReplyTo header in messages. If true, Camel does not send a reply back to the destination specified in the JMSReplyTo header. You can use this option if you want Camel to consume from a route and you do not want Camel to automatically send back a reply message because another component in your code handles the reply message. You can also use this option if you want to use Camel as a proxy between different message brokers and you want to route message from one system to another.

false

boolean

durableSubscriptionName (common)

The durable subscriber name for specifying durable topic subscriptions. The clientId option must be configured as well.

String

embedded (common)

Use an embedded in-memory (non-persistent) ActiveMQ broker for development and testing purposes. You must have activemq-broker JAR on the classpath.

false

boolean

jmsMessageType (common)

Allows you to force the use of a specific jakarta.jms.Message implementation for sending JMS messages. Possible values are: Bytes, Map, Object, Stream, Text. By default, Camel would determine which JMS message type to use from the In body type. This option allows you to specify it.

Enum values:

  • Bytes

  • Map

  • Object

  • Stream

  • Text

JmsMessageType

replyTo (common)

Provides an explicit ReplyTo destination (overrides any incoming value of Message.getJMSReplyTo() in consumer).

String

testConnectionOnStartup (common)

Specifies whether to test the connection on startup. This ensures that when Camel starts that all the JMS consumers have a valid connection to the JMS broker. If a connection cannot be granted then Camel throws an exception on startup. This ensures that Camel is not started with failed connections. The JMS producers is tested as well.

false

boolean

usePooledConnection (common)

Enables or disables whether a PooledConnectionFactory will be used so that when messages are sent to ActiveMQ from outside a message consuming thread, pooling will be used rather than the default with the Spring JmsTemplate which will create a new connection, session, producer for each message then close them all down again. The default value is true.

true

boolean

useSingleConnection (common)

Enables or disables whether a Spring SingleConnectionFactory will be used so that when messages are sent to ActiveMQ from outside a message consuming thread, pooling will be used rather than the default with the Spring JmsTemplate which will create a new connection, session, producer for each message then close them all down again. The default value is false and a pooled connection is used by default.

false

boolean

acknowledgementModeName (consumer)

The JMS acknowledgement name, which is one of: SESSION_TRANSACTED, CLIENT_ACKNOWLEDGE, AUTO_ACKNOWLEDGE, DUPS_OK_ACKNOWLEDGE.

Enum values:

  • SESSION_TRANSACTED

  • CLIENT_ACKNOWLEDGE

  • AUTO_ACKNOWLEDGE

  • DUPS_OK_ACKNOWLEDGE

AUTO_ACKNOWLEDGE

String

artemisConsumerPriority (consumer)

Consumer priorities allow you to ensure that high priority consumers receive messages while they are active. Normally, active consumers connected to a queue receive messages from it in a round-robin fashion. When consumer priorities are in use, messages are delivered round-robin if multiple active consumers exist with the same high priority. Messages will only going to lower priority consumers when the high priority consumers do not have credit available to consume the message, or those high priority consumers have declined to accept the message (for instance because it does not meet the criteria of any selectors associated with the consumer).

int

asyncConsumer (consumer)

Whether the JmsConsumer processes the Exchange asynchronously. If enabled then the JmsConsumer may pickup the next message from the JMS queue, while the previous message is being processed asynchronously (by the Asynchronous Routing Engine). This means that messages may be processed not 100% strictly in order. If disabled (as default) then the Exchange is fully processed before the JmsConsumer will pickup the next message from the JMS queue. Note if transacted has been enabled, then asyncConsumer=true does not run asynchronously, as transaction must be executed synchronously.

false

boolean

autoStartup (consumer)

Specifies whether the consumer container should auto-startup.

true

boolean

cacheLevel (consumer)

Sets the cache level by ID for the underlying JMS resources. See cacheLevelName option for more details.

int

cacheLevelName (consumer)

Sets the cache level by name for the underlying JMS resources. Possible values are: CACHE_AUTO, CACHE_CONNECTION, CACHE_CONSUMER, CACHE_NONE, and CACHE_SESSION. The default setting is CACHE_AUTO. See the Spring documentation and Transactions Cache Levels for more information.

Enum values:

  • CACHE_AUTO

  • CACHE_CONNECTION

  • CACHE_CONSUMER

  • CACHE_NONE

  • CACHE_SESSION

CACHE_AUTO

String

concurrentConsumers (consumer)

Specifies the default number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToConcurrentConsumers is used to control number of concurrent consumers on the reply message listener.

1

int

maxConcurrentConsumers (consumer)

Specifies the maximum number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToMaxConcurrentConsumers is used to control number of concurrent consumers on the reply message listener.

int

replyToDeliveryPersistent (consumer)

Specifies whether to use persistent delivery by default for replies.

true

boolean

selector (consumer)

Sets the JMS selector to use.

String

subscriptionDurable (consumer)

Set whether to make the subscription durable. The durable subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a durable subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well.

false

boolean

subscriptionName (consumer)

Set the name of a subscription to create. To be applied in case of a topic (pub-sub domain) with a shared or durable subscription. The subscription name needs to be unique within this client’s JMS client id. Default is the class name of the specified message listener. Note: Only 1 concurrent consumer (which is the default of this message listener container) is allowed for each subscription, except for a shared subscription (which requires JMS 2.0).

String

subscriptionShared (consumer)

Set whether to make the subscription shared. The shared subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a shared subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Note that shared subscriptions may also be durable, so this flag can (and often will) be combined with subscriptionDurable as well. Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. Requires a JMS 2.0 compatible message broker.

false

boolean

acceptMessagesWhileStopping (consumer (advanced))

Specifies whether the consumer accept messages while it is stopping. You may consider enabling this option, if you start and stop JMS routes at runtime, while there are still messages enqueued on the queue. If this option is false, and you stop the JMS route, then messages may be rejected, and the JMS broker would have to attempt redeliveries, which yet again may be rejected, and eventually the message may be moved at a dead letter queue on the JMS broker. To avoid this its recommended to enable this option.

false

boolean

allowReplyManagerQuickStop (consumer (advanced))

Whether the DefaultMessageListenerContainer used in the reply managers for request-reply messaging allow the DefaultMessageListenerContainer.runningAllowed flag to quick stop in case JmsConfiguration#isAcceptMessagesWhileStopping is enabled, and org.apache.camel.CamelContext is currently being stopped. This quick stop ability is enabled by default in the regular JMS consumers but to enable for reply managers you must enable this flag.

false

boolean

consumerType (consumer (advanced))

The consumer type to use, which can be one of: Simple, Default, or Custom. The consumer type determines which Spring JMS listener to use. Default will use org.springframework.jms.listener.DefaultMessageListenerContainer, Simple will use org.springframework.jms.listener.SimpleMessageListenerContainer. When Custom is specified, the MessageListenerContainerFactory defined by the messageListenerContainerFactory option will determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use.

Enum values:

  • Simple

  • Default

  • Custom

Default

ConsumerType

defaultTaskExecutorType (consumer (advanced))

Specifies what default TaskExecutor type to use in the DefaultMessageListenerContainer, for both consumer endpoints and the ReplyTo consumer of producer endpoints. Possible values: SimpleAsync (uses Spring’s SimpleAsyncTaskExecutor) or ThreadPool (uses Spring’s ThreadPoolTaskExecutor with optimal values - cached thread-pool-like). If not set, it defaults to the previous behaviour, which uses a cached thread pool for consumer endpoints and SimpleAsync for reply consumers. The use of ThreadPool is recommended to reduce thread trash in elastic configurations with dynamically increasing and decreasing concurrent consumers.

Enum values:

  • ThreadPool

  • SimpleAsync

DefaultTaskExecutorType

eagerLoadingOfProperties (consumer (advanced))

Enables eager loading of JMS properties and payload as soon as a message is loaded which generally is inefficient as the JMS properties may not be required but sometimes can catch early any issues with the underlying JMS provider and the use of JMS properties. See also the option eagerPoisonBody.

false

boolean

eagerPoisonBody (consumer (advanced))

If eagerLoadingOfProperties is enabled and the JMS message payload (JMS body or JMS properties) is poison (cannot be read/mapped), then set this text as the message body instead so the message can be processed (the cause of the poison are already stored as exception on the Exchange). This can be turned off by setting eagerPoisonBody=false. See also the option eagerLoadingOfProperties.

Poison JMS message due to ${exception.message}

String

exposeListenerSession (consumer (advanced))

Specifies whether the listener session should be exposed when consuming messages.

false

boolean

replyToConsumerType (consumer (advanced))

The consumer type of the reply consumer (when doing request/reply), which can be one of: Simple, Default, or Custom. The consumer type determines which Spring JMS listener to use. Default will use org.springframework.jms.listener.DefaultMessageListenerContainer, Simple will use org.springframework.jms.listener.SimpleMessageListenerContainer. When Custom is specified, the MessageListenerContainerFactory defined by the messageListenerContainerFactory option will determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use.

Enum values:

  • Simple

  • Default

  • Custom

Default

ConsumerType

replyToSameDestinationAllowed (consumer (advanced))

Whether a JMS consumer is allowed to send a reply message to the same destination that the consumer is using to consume from. This prevents an endless loop by consuming and sending back the same message to itself.

false

boolean

taskExecutor (consumer (advanced))

Allows you to specify a custom task executor for consuming messages.

TaskExecutor

deliveryDelay (producer)

Sets delivery delay to use for send calls for JMS. This option requires JMS 2.0 compliant broker.

-1

long

deliveryMode (producer)

Specifies the delivery mode to be used. Possible values are those defined by jakarta.jms.DeliveryMode. NON_PERSISTENT = 1 and PERSISTENT = 2.

Enum values:

  • 1

  • 2

Integer

deliveryPersistent (producer)

Specifies whether persistent delivery is used by default.

true

boolean

explicitQosEnabled (producer)

Set if the deliveryMode, priority or timeToLive qualities of service should be used when sending messages. This option is based on Spring’s JmsTemplate. The deliveryMode, priority and timeToLive options are applied to the current endpoint. This contrasts with the preserveMessageQos option, which operates at message granularity, reading QoS properties exclusively from the Camel In message headers.

false

Boolean

formatDateHeadersToIso8601 (producer)

Sets whether JMS date properties should be formatted according to the ISO 8601 standard.

false

boolean

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

preserveMessageQos (producer)

Set to true, if you want to send message using the QoS settings specified on the message, instead of the QoS settings on the JMS endpoint. The following three headers are considered JMSPriority, JMSDeliveryMode, and JMSExpiration. You can provide all or only some of them. If not provided, Camel will fall back to use the values from the endpoint instead. So, when using this option, the headers override the values from the endpoint. The explicitQosEnabled option, by contrast, will only use options set on the endpoint, and not values from the message header.

false

boolean

priority (producer)

Values greater than 1 specify the message priority when sending (where 1 is the lowest priority and 9 is the highest). The explicitQosEnabled option must also be enabled in order for this option to have any effect.

Enum values:

  • 1

  • 2

  • 3

  • 4

  • 5

  • 6

  • 7

  • 8

  • 9

4

int

replyToConcurrentConsumers (producer)

Specifies the default number of concurrent consumers when doing request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads.

1

int

replyToMaxConcurrentConsumers (producer)

Specifies the maximum number of concurrent consumers when using request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads.

int

replyToOnTimeoutMaxConcurrentConsumers (producer)

Specifies the maximum number of concurrent consumers for continue routing when timeout occurred when using request/reply over JMS.

1

int

replyToOverride (producer)

Provides an explicit ReplyTo destination in the JMS message, which overrides the setting of replyTo. It is useful if you want to forward the message to a remote Queue and receive the reply message from the ReplyTo destination.

String

replyToType (producer)

Allows for explicitly specifying which kind of strategy to use for replyTo queues when doing request/reply over JMS. Possible values are: Temporary, Shared, or Exclusive. By default Camel will use temporary queues. However if replyTo has been configured, then Shared is used by default. This option allows you to use exclusive queues instead of shared ones. See Camel JMS documentation for more details, and especially the notes about the implications if running in a clustered environment, and the fact that Shared reply queues has lower performance than its alternatives Temporary and Exclusive.

Enum values:

  • Temporary

  • Shared

  • Exclusive

ReplyToType

requestTimeout (producer)

The timeout for waiting for a reply when using the InOut Exchange Pattern (in milliseconds). The default is 20 seconds. You can include the header CamelJmsRequestTimeout to override this endpoint configured timeout value, and thus have per message individual timeout values. See also the requestTimeoutCheckerInterval option.

20000

long

timeToLive (producer)

When sending messages, specifies the time-to-live of the message (in milliseconds).

-1

long

allowAdditionalHeaders (producer (advanced))

This option is used to allow additional headers which may have values that are invalid according to JMS specification. For example, some message systems, such as WMQ, do this with header names using prefix JMS_IBM_MQMD_ containing values with byte array or other invalid types. You can specify multiple header names separated by comma, and use as suffix for wildcard matching.

String

allowNullBody (producer (advanced))

Whether to allow sending messages with no body. If this option is false and the message body is null, then an JMSException is thrown.

true

boolean

alwaysCopyMessage (producer (advanced))

If true, Camel will always make a JMS message copy of the message when it is passed to the producer for sending. Copying the message is needed in some situations, such as when a replyToDestinationSelectorName is set (incidentally, Camel will set the alwaysCopyMessage option to true, if a replyToDestinationSelectorName is set).

false

boolean

correlationProperty (producer (advanced))

When using InOut exchange pattern use this JMS property instead of JMSCorrelationID JMS property to correlate messages. If set messages will be correlated solely on the value of this property JMSCorrelationID property will be ignored and not set by Camel.

String

disableTimeToLive (producer (advanced))

Use this option to force disabling time to live. For example when you do request/reply over JMS, then Camel will by default use the requestTimeout value as time to live on the message being sent. The problem is that the sender and receiver systems have to have their clocks synchronized, so they are in sync. This is not always so easy to archive. So you can use disableTimeToLive=true to not set a time to live value on the sent message. Then the message will not expire on the receiver system. See below in section About time to live for more details.

false

boolean

forceSendOriginalMessage (producer (advanced))

When using mapJmsMessage=false Camel will create a new JMS message to send to a new JMS destination if you touch the headers (get or set) during the route. Set this option to true to force Camel to send the original JMS message that was received.

false

boolean

includeSentJMSMessageID (producer (advanced))

Only applicable when sending to JMS destination using InOnly (eg fire and forget). Enabling this option will enrich the Camel Exchange with the actual JMSMessageID that was used by the JMS client when the message was sent to the JMS destination.

false

boolean

replyToCacheLevelName (producer (advanced))

Sets the cache level by name for the reply consumer when doing request/reply over JMS. This option only applies when using fixed reply queues (not temporary). Camel will by default use: CACHE_CONSUMER for exclusive or shared w/ replyToSelectorName. And CACHE_SESSION for shared without replyToSelectorName. Some JMS brokers such as IBM WebSphere may require to set the replyToCacheLevelName=CACHE_NONE to work. Note: If using temporary queues then CACHE_NONE is not allowed, and you must use a higher value such as CACHE_CONSUMER or CACHE_SESSION.

Enum values:

  • CACHE_AUTO

  • CACHE_CONNECTION

  • CACHE_CONSUMER

  • CACHE_NONE

  • CACHE_SESSION

String

replyToDestinationSelectorName (producer (advanced))

Sets the JMS Selector using the fixed name to be used so you can filter out your own replies from the others when using a shared queue (that is, if you are not using a temporary reply queue).

String

streamMessageTypeEnabled (producer (advanced))

Sets whether StreamMessage type is enabled or not. Message payloads of streaming kind such as files, InputStream, etc will either by sent as BytesMessage or StreamMessage. This option controls which kind will be used. By default BytesMessage is used which enforces the entire message payload to be read into memory. By enabling this option the message payload is read into memory in chunks and each chunk is then written to the StreamMessage until no more data.

false

boolean

allowAutoWiredConnectionFactory (advanced)

Whether to auto-discover ConnectionFactory from the registry, if no connection factory has been configured. If only one instance of ConnectionFactory is found then it will be used. This is enabled by default.

true

boolean

allowAutoWiredDestinationResolver (advanced)

Whether to auto-discover DestinationResolver from the registry, if no destination resolver has been configured. If only one instance of DestinationResolver is found then it will be used. This is enabled by default.

true

boolean

allowSerializedHeaders (advanced)

Controls whether or not to include serialized headers. Applies only when transferExchange is true. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level.

false

boolean

artemisStreamingEnabled (advanced)

Whether optimizing for Apache Artemis streaming mode. This can reduce memory overhead when using Artemis with JMS StreamMessage types. This option must only be enabled if Apache Artemis is being used.

false

boolean

asyncStartListener (advanced)

Whether to startup the JmsConsumer message listener asynchronously, when starting a route. For example if a JmsConsumer cannot get a connection to a remote JMS broker, then it may block while retrying and/or fail-over. This will cause Camel to block while starting routes. By setting this option to true, you will let routes startup, while the JmsConsumer connects to the JMS broker using a dedicated thread in asynchronous mode. If this option is used, then beware that if the connection could not be established, then an exception is logged at WARN level, and the consumer will not be able to receive messages; You can then restart the route to retry.

false

boolean

asyncStopListener (advanced)

Whether to stop the JmsConsumer message listener asynchronously, when stopping a route.

false

boolean

autowiredEnabled (advanced)

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

boolean

browseLimit (advanced)

Maximum number of messages to keep in memory available for browsing. Use 0 for unlimited.

100

int

configuration (advanced)

To use a shared JMS configuration.

JmsConfiguration

destinationResolver (advanced)

A pluggable org.springframework.jms.support.destination.DestinationResolver that allows you to use your own resolver (for example, to lookup the real destination in a JNDI registry).

DestinationResolver

errorHandler (advanced)

Specifies a org.springframework.util.ErrorHandler to be invoked in case of any uncaught exceptions thrown while processing a Message. By default these exceptions will be logged at the WARN level, if no errorHandler has been configured. You can configure logging level and whether stack traces should be logged using errorHandlerLoggingLevel and errorHandlerLogStackTrace options. This makes it much easier to configure, than having to code a custom errorHandler.

ErrorHandler

exceptionListener (advanced)

Specifies the JMS Exception Listener that is to be notified of any underlying JMS exceptions.

ExceptionListener

idleConsumerLimit (advanced)

Specify the limit for the number of consumers that are allowed to be idle at any given time.

1

int

idleReceivesPerTaskLimit (advanced)

Marks the consumer as idle after the specified number of idle receives have been reached. An idle receive is counted from the moment a null message is returned by the receiver after the potential setReceiveTimeout elapsed. This gives the opportunity to check if the idle task count exceeds setIdleTaskExecutionLimit and based on that decide if the task needs to be re-scheduled or not, saving resources that would otherwise be held. This setting differs from setMaxMessagesPerTask where the task is released and re-scheduled after this limit is reached, no matter if the received messages were null or non-null messages. This setting alone can be inflexible if one desires to have a large enough batch for each task but requires a quick(er) release from the moment there are no more messages to process. This setting differs from setIdleTaskExecutionLimit where this limit decides after how many iterations of being marked as idle, a task is released. For example: If setMaxMessagesPerTask is set to '500' and #setIdleReceivesPerTaskLimit is set to '60' and setReceiveTimeout is set to '1000' and setIdleTaskExecutionLimit is set to '1', then 500 messages per task would be processed unless there is a subsequent number of 60 idle messages received, the task would be marked as idle and released. This also means that after the last message was processed, the task would be released after 60 seconds as long as no new messages appear.

int

idleTaskExecutionLimit (advanced)

Specifies the limit for idle executions of a receive task, not having received any message within its execution. If this limit is reached, the task will shut down and leave receiving to other executing tasks (in the case of dynamic scheduling; see the maxConcurrentConsumers setting). There is additional doc available from Spring.

1

int

includeAllJMSXProperties (advanced)

Whether to include all JMSX prefixed properties when mapping from JMS to Camel Message. Setting this to true will include properties such as JMSXAppID, and JMSXUserID etc. Note: If you are using a custom headerFilterStrategy then this option does not apply.

false

boolean

includeCorrelationIDAsBytes (advanced)

Whether the JMS consumer should include JMSCorrelationIDAsBytes as a header on the Camel Message.

true

boolean

jmsKeyFormatStrategy (advanced)

Pluggable strategy for encoding and decoding JMS keys so they can be compliant with the JMS specification. Camel provides two implementations out of the box: default and passthrough. The default strategy will safely marshal dots and hyphens (. and -). The passthrough strategy leaves the key as is. Can be used for JMS brokers which do not care whether JMS header keys contain illegal characters. You can provide your own implementation of the org.apache.camel.component.jms.JmsKeyFormatStrategy and refer to it using the # notation.

Enum values:

  • default

  • passthrough

JmsKeyFormatStrategy

mapJmsMessage (advanced)

Specifies whether Camel should auto map the received JMS message to a suited payload type, such as jakarta.jms.TextMessage to a String etc.

true

boolean

maxMessagesPerTask (advanced)

The number of messages per task. -1 is unlimited. If you use a range for concurrent consumers (eg min max), then this option can be used to set a value to eg 100 to control how fast the consumers will shrink when less work is required.

-1

int

messageConverter (advanced)

To use a custom Spring org.springframework.jms.support.converter.MessageConverter so you can be in control how to map to/from a jakarta.jms.Message.

MessageConverter

messageCreatedStrategy (advanced)

To use the given MessageCreatedStrategy which are invoked when Camel creates new instances of jakarta.jms.Message objects when Camel is sending a JMS message.

MessageCreatedStrategy

messageIdEnabled (advanced)

When sending, specifies whether message IDs should be added. This is just an hint to the JMS broker. If the JMS provider accepts this hint, these messages must have the message ID set to null; if the provider ignores the hint, the message ID must be set to its normal unique value.

true

boolean

messageListenerContainerFactory (advanced)

Registry ID of the MessageListenerContainerFactory used to determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use to consume messages. Setting this will automatically set consumerType to Custom.

MessageListenerContainerFactory

messageTimestampEnabled (advanced)

Specifies whether timestamps should be enabled by default on sending messages. This is just an hint to the JMS broker. If the JMS provider accepts this hint, these messages must have the timestamp set to zero; if the provider ignores the hint the timestamp must be set to its normal value.

true

boolean

pubSubNoLocal (advanced)

Specifies whether to inhibit the delivery of messages published by its own connection.

false

boolean

queueBrowseStrategy (advanced)

To use a custom QueueBrowseStrategy when browsing queues.

QueueBrowseStrategy

receiveTimeout (advanced)

The timeout for receiving messages (in milliseconds).

1000

long

recoveryInterval (advanced)

Specifies the interval between recovery attempts, i.e. when a connection is being refreshed, in milliseconds. The default is 5000 ms, that is, 5 seconds.

5000

long

requestTimeoutCheckerInterval (advanced)

Configures how often Camel should check for timed out Exchanges when doing request/reply over JMS. By default Camel checks once per second. But if you must react faster when a timeout occurs, then you can lower this interval, to check more frequently. The timeout is determined by the option requestTimeout.

1000

long

serviceLocationEnabled (advanced)

Whether to detect the network address location of the JMS broker on startup. This information is gathered via reflection on the ConnectionFactory, and is vendor specific. This option can be used to turn this off.

true

boolean

synchronous (advanced)

Sets whether synchronous processing should be strictly used.

false

boolean

temporaryQueueResolver (advanced)

A pluggable TemporaryQueueResolver that allows you to use your own resolver for creating temporary queues (some messaging systems has special requirements for creating temporary queues).

TemporaryQueueResolver

transferException (advanced)

If enabled and you are using Request Reply messaging (InOut) and an Exchange failed on the consumer side, then the caused Exception will be send back in response as a jakarta.jms.ObjectMessage. If the client is Camel, the returned Exception is rethrown. This allows you to use Camel JMS as a bridge in your routing - for example, using persistent queues to enable robust routing. Notice that if you also have transferExchange enabled, this option takes precedence. The caught exception is required to be serializable. The original Exception on the consumer side can be wrapped in an outer exception such as org.apache.camel.RuntimeCamelException when returned to the producer. Use this with caution as the data is using Java Object serialization and requires the received to be able to deserialize the data at Class level, which forces a strong coupling between the producers and consumer!.

false

boolean

transferExchange (advanced)

You can transfer the exchange over the wire instead of just the body and headers. The following fields are transferred: In body, Out body, Fault body, In headers, Out headers, Fault headers, exchange properties, exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. You must enable this option on both the producer and consumer side, so Camel knows the payloads is an Exchange and not a regular payload. Use this with caution as the data is using Java Object serialization and requires the receiver to be able to deserialize the data at Class level, which forces a strong coupling between the producers and consumers having to use compatible Camel versions!.

false

boolean

trustAllPackages (advanced)

Define if all Java packages are trusted or not (for Java object JMS message types). Notice its not recommended practice to send Java serialized objects over network. Setting this to true can expose security risks, so use this with care.

false

boolean

useMessageIDAsCorrelationID (advanced)

Specifies whether JMSMessageID should always be used as JMSCorrelationID for InOut messages.

false

boolean

waitForProvisionCorrelationToBeUpdatedCounter (advanced)

waitForTemporaryReplyToToBeUpdatedCounter (advanced)

Number of times to wait for temporary replyTo queue to be created and ready when doing request/reply over JMS.

200

int

waitForTemporaryReplyToToBeUpdatedThreadSleepingTime (advanced)

Interval in millis to sleep each time while waiting for temporary replyTo queue to be ready.

100

long

headerFilterStrategy (filter)

To use a custom org.apache.camel.spi.HeaderFilterStrategy to filter header to and from Camel message.

HeaderFilterStrategy

errorHandlerLoggingLevel (logging)

Allows to configure the default errorHandler logging level for logging uncaught exceptions.

Enum values:

  • TRACE

  • DEBUG

  • INFO

  • WARN

  • ERROR

  • OFF

WARN

LoggingLevel

errorHandlerLogStackTrace (logging)

Allows to control whether stack-traces should be logged or not, by the default errorHandler.

true

boolean

password (security)

Password to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory.

String

username (security)

Username to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory.

String

transacted (transaction)

Specifies whether to use transacted mode.

false

boolean

transactedInOut (transaction)

Specifies whether InOut operations (request reply) default to using transacted mode If this flag is set to true, then Spring JmsTemplate will have sessionTransacted set to true, and the acknowledgeMode as transacted on the JmsTemplate used for InOut operations. Note from Spring JMS: that within a JTA transaction, the parameters passed to createQueue, createTopic methods are not taken into account. Depending on the Java EE transaction context, the container makes its own decisions on these values. Analogously, these parameters are not taken into account within a locally managed transaction either, since Spring JMS operates on an existing JMS Session in this case. Setting this flag to true will use a short local JMS transaction when running outside of a managed transaction, and a synchronized local JMS transaction in case of a managed transaction (other than an XA transaction) being present. This has the effect of a local JMS transaction being managed alongside the main transaction (which might be a native JDBC transaction), with the JMS transaction committing right after the main transaction.

false

boolean

lazyCreateTransactionManager (transaction (advanced))

If true, Camel will create a JmsTransactionManager, if there is no transactionManager injected when option transacted=true.

true

boolean

transactionManager (transaction (advanced))

The Spring transaction manager to use.

PlatformTransactionManager

activemq:destinationType:destinationName

With the following path and query parameters:

Path Parameters (2 parameters)

Name Description Default Type

destinationType (common)

The kind of destination to use.

Enum values:

  • queue

  • topic

  • temp-queue

  • temp-topic

queue

String

destinationName (common)

Required Name of the queue or topic to use as destination.

String

Query Parameters (102 parameters)

Name Description Default Type

clientId (common)

Sets the JMS client ID to use. Note that this value, if specified, must be unique and can only be used by a single JMS connection instance. It is typically only required for durable topic subscriptions with JMS 1.1.

String

connectionFactory (common)

The connection factory to be use. A connection factory must be configured either on the component or endpoint.

ConnectionFactory

disableReplyTo (common)

Specifies whether Camel ignores the JMSReplyTo header in messages. If true, Camel does not send a reply back to the destination specified in the JMSReplyTo header. You can use this option if you want Camel to consume from a route and you do not want Camel to automatically send back a reply message because another component in your code handles the reply message. You can also use this option if you want to use Camel as a proxy between different message brokers and you want to route message from one system to another.

false

boolean

durableSubscriptionName (common)

The durable subscriber name for specifying durable topic subscriptions. The clientId option must be configured as well.

String

jmsMessageType (common)

Allows you to force the use of a specific jakarta.jms.Message implementation for sending JMS messages. Possible values are: Bytes, Map, Object, Stream, Text. By default, Camel would determine which JMS message type to use from the In body type. This option allows you to specify it.

Enum values:

  • Bytes

  • Map

  • Object

  • Stream

  • Text

JmsMessageType

replyTo (common)

Provides an explicit ReplyTo destination (overrides any incoming value of Message.getJMSReplyTo() in consumer).

String

testConnectionOnStartup (common)

Specifies whether to test the connection on startup. This ensures that when Camel starts that all the JMS consumers have a valid connection to the JMS broker. If a connection cannot be granted then Camel throws an exception on startup. This ensures that Camel is not started with failed connections. The JMS producers is tested as well.

false

boolean

acknowledgementModeName (consumer)

The JMS acknowledgement name, which is one of: SESSION_TRANSACTED, CLIENT_ACKNOWLEDGE, AUTO_ACKNOWLEDGE, DUPS_OK_ACKNOWLEDGE.

Enum values:

  • SESSION_TRANSACTED

  • CLIENT_ACKNOWLEDGE

  • AUTO_ACKNOWLEDGE

  • DUPS_OK_ACKNOWLEDGE

AUTO_ACKNOWLEDGE

String

artemisConsumerPriority (consumer)

Consumer priorities allow you to ensure that high priority consumers receive messages while they are active. Normally, active consumers connected to a queue receive messages from it in a round-robin fashion. When consumer priorities are in use, messages are delivered round-robin if multiple active consumers exist with the same high priority. Messages will only going to lower priority consumers when the high priority consumers do not have credit available to consume the message, or those high priority consumers have declined to accept the message (for instance because it does not meet the criteria of any selectors associated with the consumer).

int

asyncConsumer (consumer)

Whether the JmsConsumer processes the Exchange asynchronously. If enabled then the JmsConsumer may pickup the next message from the JMS queue, while the previous message is being processed asynchronously (by the Asynchronous Routing Engine). This means that messages may be processed not 100% strictly in order. If disabled (as default) then the Exchange is fully processed before the JmsConsumer will pickup the next message from the JMS queue. Note if transacted has been enabled, then asyncConsumer=true does not run asynchronously, as transaction must be executed synchronously.

false

boolean

autoStartup (consumer)

Specifies whether the consumer container should auto-startup.

true

boolean

cacheLevel (consumer)

Sets the cache level by ID for the underlying JMS resources. See cacheLevelName option for more details.

int

cacheLevelName (consumer)

Sets the cache level by name for the underlying JMS resources. Possible values are: CACHE_AUTO, CACHE_CONNECTION, CACHE_CONSUMER, CACHE_NONE, and CACHE_SESSION. The default setting is CACHE_AUTO. See the Spring documentation and Transactions Cache Levels for more information.

Enum values:

  • CACHE_AUTO

  • CACHE_CONNECTION

  • CACHE_CONSUMER

  • CACHE_NONE

  • CACHE_SESSION

CACHE_AUTO

String

concurrentConsumers (consumer)

Specifies the default number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToConcurrentConsumers is used to control number of concurrent consumers on the reply message listener.

1

int

maxConcurrentConsumers (consumer)

Specifies the maximum number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToMaxConcurrentConsumers is used to control number of concurrent consumers on the reply message listener.

int

replyToDeliveryPersistent (consumer)

Specifies whether to use persistent delivery by default for replies.

true

boolean

selector (consumer)

Sets the JMS selector to use.

String

subscriptionDurable (consumer)

Set whether to make the subscription durable. The durable subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a durable subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well.

false

boolean

subscriptionName (consumer)

Set the name of a subscription to create. To be applied in case of a topic (pub-sub domain) with a shared or durable subscription. The subscription name needs to be unique within this client’s JMS client id. Default is the class name of the specified message listener. Note: Only 1 concurrent consumer (which is the default of this message listener container) is allowed for each subscription, except for a shared subscription (which requires JMS 2.0).

String

subscriptionShared (consumer)

Set whether to make the subscription shared. The shared subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a shared subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Note that shared subscriptions may also be durable, so this flag can (and often will) be combined with subscriptionDurable as well. Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. Requires a JMS 2.0 compatible message broker.

false

boolean

acceptMessagesWhileStopping (consumer (advanced))

Specifies whether the consumer accept messages while it is stopping. You may consider enabling this option, if you start and stop JMS routes at runtime, while there are still messages enqueued on the queue. If this option is false, and you stop the JMS route, then messages may be rejected, and the JMS broker would have to attempt redeliveries, which yet again may be rejected, and eventually the message may be moved at a dead letter queue on the JMS broker. To avoid this its recommended to enable this option.

false

boolean

allowReplyManagerQuickStop (consumer (advanced))

Whether the DefaultMessageListenerContainer used in the reply managers for request-reply messaging allow the DefaultMessageListenerContainer.runningAllowed flag to quick stop in case JmsConfiguration#isAcceptMessagesWhileStopping is enabled, and org.apache.camel.CamelContext is currently being stopped. This quick stop ability is enabled by default in the regular JMS consumers but to enable for reply managers you must enable this flag.

false

boolean

consumerType (consumer (advanced))

The consumer type to use, which can be one of: Simple, Default, or Custom. The consumer type determines which Spring JMS listener to use. Default will use org.springframework.jms.listener.DefaultMessageListenerContainer, Simple will use org.springframework.jms.listener.SimpleMessageListenerContainer. When Custom is specified, the MessageListenerContainerFactory defined by the messageListenerContainerFactory option will determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use.

Enum values:

  • Simple

  • Default

  • Custom

Default

ConsumerType

defaultTaskExecutorType (consumer (advanced))

Specifies what default TaskExecutor type to use in the DefaultMessageListenerContainer, for both consumer endpoints and the ReplyTo consumer of producer endpoints. Possible values: SimpleAsync (uses Spring’s SimpleAsyncTaskExecutor) or ThreadPool (uses Spring’s ThreadPoolTaskExecutor with optimal values - cached thread-pool-like). If not set, it defaults to the previous behaviour, which uses a cached thread pool for consumer endpoints and SimpleAsync for reply consumers. The use of ThreadPool is recommended to reduce thread trash in elastic configurations with dynamically increasing and decreasing concurrent consumers.

Enum values:

  • ThreadPool

  • SimpleAsync

DefaultTaskExecutorType

destinationOptions (consumer (advanced))

Destination Options are a way to provide extended configuration options to a JMS consumer without having to extend the JMS API. The options are encoded using URL query syntax in the destination name that the consumer is created on. See more details at https://activemq.apache.org/destination-options.

Map

eagerLoadingOfProperties (consumer (advanced))

Enables eager loading of JMS properties and payload as soon as a message is loaded which generally is inefficient as the JMS properties may not be required but sometimes can catch early any issues with the underlying JMS provider and the use of JMS properties. See also the option eagerPoisonBody.

false

boolean

eagerPoisonBody (consumer (advanced))

If eagerLoadingOfProperties is enabled and the JMS message payload (JMS body or JMS properties) is poison (cannot be read/mapped), then set this text as the message body instead so the message can be processed (the cause of the poison are already stored as exception on the Exchange). This can be turned off by setting eagerPoisonBody=false. See also the option eagerLoadingOfProperties.

Poison JMS message due to ${exception.message}

String

exceptionHandler (consumer (advanced))

To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.

ExceptionHandler

exchangePattern (consumer (advanced))

Sets the exchange pattern when the consumer creates an exchange.

Enum values:

  • InOnly

  • InOut

ExchangePattern

exposeListenerSession (consumer (advanced))

Specifies whether the listener session should be exposed when consuming messages.

false

boolean

replyToConsumerType (consumer (advanced))

The consumer type of the reply consumer (when doing request/reply), which can be one of: Simple, Default, or Custom. The consumer type determines which Spring JMS listener to use. Default will use org.springframework.jms.listener.DefaultMessageListenerContainer, Simple will use org.springframework.jms.listener.SimpleMessageListenerContainer. When Custom is specified, the MessageListenerContainerFactory defined by the messageListenerContainerFactory option will determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use.

Enum values:

  • Simple

  • Default

  • Custom

Default

ConsumerType

replyToSameDestinationAllowed (consumer (advanced))

Whether a JMS consumer is allowed to send a reply message to the same destination that the consumer is using to consume from. This prevents an endless loop by consuming and sending back the same message to itself.

false

boolean

taskExecutor (consumer (advanced))

Allows you to specify a custom task executor for consuming messages.

TaskExecutor

deliveryDelay (producer)

Sets delivery delay to use for send calls for JMS. This option requires JMS 2.0 compliant broker.

-1

long

deliveryMode (producer)

Specifies the delivery mode to be used. Possible values are those defined by jakarta.jms.DeliveryMode. NON_PERSISTENT = 1 and PERSISTENT = 2.

Enum values:

  • 1

  • 2

Integer

deliveryPersistent (producer)

Specifies whether persistent delivery is used by default.

true

boolean

explicitQosEnabled (producer)

Set if the deliveryMode, priority or timeToLive qualities of service should be used when sending messages. This option is based on Spring’s JmsTemplate. The deliveryMode, priority and timeToLive options are applied to the current endpoint. This contrasts with the preserveMessageQos option, which operates at message granularity, reading QoS properties exclusively from the Camel In message headers.

false

Boolean

formatDateHeadersToIso8601 (producer)

Sets whether JMS date properties should be formatted according to the ISO 8601 standard.

false

boolean

preserveMessageQos (producer)

Set to true, if you want to send message using the QoS settings specified on the message, instead of the QoS settings on the JMS endpoint. The following three headers are considered JMSPriority, JMSDeliveryMode, and JMSExpiration. You can provide all or only some of them. If not provided, Camel will fall back to use the values from the endpoint instead. So, when using this option, the headers override the values from the endpoint. The explicitQosEnabled option, by contrast, will only use options set on the endpoint, and not values from the message header.

false

boolean

priority (producer)

Values greater than 1 specify the message priority when sending (where 1 is the lowest priority and 9 is the highest). The explicitQosEnabled option must also be enabled in order for this option to have any effect.

Enum values:

  • 1

  • 2

  • 3

  • 4

  • 5

  • 6

  • 7

  • 8

  • 9

4

int

replyToConcurrentConsumers (producer)

Specifies the default number of concurrent consumers when doing request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads.

1

int

replyToMaxConcurrentConsumers (producer)

Specifies the maximum number of concurrent consumers when using request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads.

int

replyToOnTimeoutMaxConcurrentConsumers (producer)

Specifies the maximum number of concurrent consumers for continue routing when timeout occurred when using request/reply over JMS.

1

int

replyToOverride (producer)

Provides an explicit ReplyTo destination in the JMS message, which overrides the setting of replyTo. It is useful if you want to forward the message to a remote Queue and receive the reply message from the ReplyTo destination.

String

replyToType (producer)

Allows for explicitly specifying which kind of strategy to use for replyTo queues when doing request/reply over JMS. Possible values are: Temporary, Shared, or Exclusive. By default Camel will use temporary queues. However if replyTo has been configured, then Shared is used by default. This option allows you to use exclusive queues instead of shared ones. See Camel JMS documentation for more details, and especially the notes about the implications if running in a clustered environment, and the fact that Shared reply queues has lower performance than its alternatives Temporary and Exclusive.

Enum values:

  • Temporary

  • Shared

  • Exclusive

ReplyToType

requestTimeout (producer)

The timeout for waiting for a reply when using the InOut Exchange Pattern (in milliseconds). The default is 20 seconds. You can include the header CamelJmsRequestTimeout to override this endpoint configured timeout value, and thus have per message individual timeout values. See also the requestTimeoutCheckerInterval option.

20000

long

timeToLive (producer)

When sending messages, specifies the time-to-live of the message (in milliseconds).

-1

long

allowAdditionalHeaders (producer (advanced))

This option is used to allow additional headers which may have values that are invalid according to JMS specification. For example, some message systems, such as WMQ, do this with header names using prefix JMS_IBM_MQMD_ containing values with byte array or other invalid types. You can specify multiple header names separated by comma, and use as suffix for wildcard matching.

String

allowNullBody (producer (advanced))

Whether to allow sending messages with no body. If this option is false and the message body is null, then an JMSException is thrown.

true

boolean

alwaysCopyMessage (producer (advanced))

If true, Camel will always make a JMS message copy of the message when it is passed to the producer for sending. Copying the message is needed in some situations, such as when a replyToDestinationSelectorName is set (incidentally, Camel will set the alwaysCopyMessage option to true, if a replyToDestinationSelectorName is set).

false

boolean

correlationProperty (producer (advanced))

When using InOut exchange pattern use this JMS property instead of JMSCorrelationID JMS property to correlate messages. If set messages will be correlated solely on the value of this property JMSCorrelationID property will be ignored and not set by Camel.

String

disableTimeToLive (producer (advanced))

Use this option to force disabling time to live. For example when you do request/reply over JMS, then Camel will by default use the requestTimeout value as time to live on the message being sent. The problem is that the sender and receiver systems have to have their clocks synchronized, so they are in sync. This is not always so easy to archive. So you can use disableTimeToLive=true to not set a time to live value on the sent message. Then the message will not expire on the receiver system. See below in section About time to live for more details.

false

boolean

forceSendOriginalMessage (producer (advanced))

When using mapJmsMessage=false Camel will create a new JMS message to send to a new JMS destination if you touch the headers (get or set) during the route. Set this option to true to force Camel to send the original JMS message that was received.

false

boolean

includeSentJMSMessageID (producer (advanced))

Only applicable when sending to JMS destination using InOnly (eg fire and forget). Enabling this option will enrich the Camel Exchange with the actual JMSMessageID that was used by the JMS client when the message was sent to the JMS destination.

false

boolean

lazyStartProducer (producer (advanced))

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

replyToCacheLevelName (producer (advanced))

Sets the cache level by name for the reply consumer when doing request/reply over JMS. This option only applies when using fixed reply queues (not temporary). Camel will by default use: CACHE_CONSUMER for exclusive or shared w/ replyToSelectorName. And CACHE_SESSION for shared without replyToSelectorName. Some JMS brokers such as IBM WebSphere may require to set the replyToCacheLevelName=CACHE_NONE to work. Note: If using temporary queues then CACHE_NONE is not allowed, and you must use a higher value such as CACHE_CONSUMER or CACHE_SESSION.

Enum values:

  • CACHE_AUTO

  • CACHE_CONNECTION

  • CACHE_CONSUMER

  • CACHE_NONE

  • CACHE_SESSION

String

replyToDestinationSelectorName (producer (advanced))

Sets the JMS Selector using the fixed name to be used so you can filter out your own replies from the others when using a shared queue (that is, if you are not using a temporary reply queue).

String

streamMessageTypeEnabled (producer (advanced))

Sets whether StreamMessage type is enabled or not. Message payloads of streaming kind such as files, InputStream, etc will either by sent as BytesMessage or StreamMessage. This option controls which kind will be used. By default BytesMessage is used which enforces the entire message payload to be read into memory. By enabling this option the message payload is read into memory in chunks and each chunk is then written to the StreamMessage until no more data.

false

boolean

allowSerializedHeaders (advanced)

Controls whether or not to include serialized headers. Applies only when transferExchange is true. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level.

false

boolean

artemisStreamingEnabled (advanced)

Whether optimizing for Apache Artemis streaming mode. This can reduce memory overhead when using Artemis with JMS StreamMessage types. This option must only be enabled if Apache Artemis is being used.

false

boolean

asyncStartListener (advanced)

Whether to startup the JmsConsumer message listener asynchronously, when starting a route. For example if a JmsConsumer cannot get a connection to a remote JMS broker, then it may block while retrying and/or fail-over. This will cause Camel to block while starting routes. By setting this option to true, you will let routes startup, while the JmsConsumer connects to the JMS broker using a dedicated thread in asynchronous mode. If this option is used, then beware that if the connection could not be established, then an exception is logged at WARN level, and the consumer will not be able to receive messages; You can then restart the route to retry.

false

boolean

asyncStopListener (advanced)

Whether to stop the JmsConsumer message listener asynchronously, when stopping a route.

false

boolean

browseLimit (advanced)

Maximum number of messages to keep in memory available for browsing. Use 0 for unlimited.

100

int

destinationResolver (advanced)

A pluggable org.springframework.jms.support.destination.DestinationResolver that allows you to use your own resolver (for example, to lookup the real destination in a JNDI registry).

DestinationResolver

errorHandler (advanced)

Specifies a org.springframework.util.ErrorHandler to be invoked in case of any uncaught exceptions thrown while processing a Message. By default these exceptions will be logged at the WARN level, if no errorHandler has been configured. You can configure logging level and whether stack traces should be logged using errorHandlerLoggingLevel and errorHandlerLogStackTrace options. This makes it much easier to configure, than having to code a custom errorHandler.

ErrorHandler

exceptionListener (advanced)

Specifies the JMS Exception Listener that is to be notified of any underlying JMS exceptions.

ExceptionListener

headerFilterStrategy (advanced)

To use a custom HeaderFilterStrategy to filter header to and from Camel message.

HeaderFilterStrategy

idleConsumerLimit (advanced)

Specify the limit for the number of consumers that are allowed to be idle at any given time.

1

int

idleReceivesPerTaskLimit (advanced)

Marks the consumer as idle after the specified number of idle receives have been reached. An idle receive is counted from the moment a null message is returned by the receiver after the potential setReceiveTimeout elapsed. This gives the opportunity to check if the idle task count exceeds setIdleTaskExecutionLimit and based on that decide if the task needs to be re-scheduled or not, saving resources that would otherwise be held. This setting differs from setMaxMessagesPerTask where the task is released and re-scheduled after this limit is reached, no matter if the received messages were null or non-null messages. This setting alone can be inflexible if one desires to have a large enough batch for each task but requires a quick(er) release from the moment there are no more messages to process. This setting differs from setIdleTaskExecutionLimit where this limit decides after how many iterations of being marked as idle, a task is released. For example: If setMaxMessagesPerTask is set to '500' and #setIdleReceivesPerTaskLimit is set to '60' and setReceiveTimeout is set to '1000' and setIdleTaskExecutionLimit is set to '1', then 500 messages per task would be processed unless there is a subsequent number of 60 idle messages received, the task would be marked as idle and released. This also means that after the last message was processed, the task would be released after 60 seconds as long as no new messages appear.

int

idleTaskExecutionLimit (advanced)

Specifies the limit for idle executions of a receive task, not having received any message within its execution. If this limit is reached, the task will shut down and leave receiving to other executing tasks (in the case of dynamic scheduling; see the maxConcurrentConsumers setting). There is additional doc available from Spring.

1

int

includeAllJMSXProperties (advanced)

Whether to include all JMSX prefixed properties when mapping from JMS to Camel Message. Setting this to true will include properties such as JMSXAppID, and JMSXUserID etc. Note: If you are using a custom headerFilterStrategy then this option does not apply.

false

boolean

jmsKeyFormatStrategy (advanced)

Pluggable strategy for encoding and decoding JMS keys so they can be compliant with the JMS specification. Camel provides two implementations out of the box: default and passthrough. The default strategy will safely marshal dots and hyphens (. and -). The passthrough strategy leaves the key as is. Can be used for JMS brokers which do not care whether JMS header keys contain illegal characters. You can provide your own implementation of the org.apache.camel.component.jms.JmsKeyFormatStrategy and refer to it using the # notation.

Enum values:

  • default

  • passthrough

JmsKeyFormatStrategy

mapJmsMessage (advanced)

Specifies whether Camel should auto map the received JMS message to a suited payload type, such as jakarta.jms.TextMessage to a String etc.

true

boolean

maxMessagesPerTask (advanced)

The number of messages per task. -1 is unlimited. If you use a range for concurrent consumers (eg min max), then this option can be used to set a value to eg 100 to control how fast the consumers will shrink when less work is required.

-1

int

messageConverter (advanced)

To use a custom Spring org.springframework.jms.support.converter.MessageConverter so you can be in control how to map to/from a jakarta.jms.Message.

MessageConverter

messageCreatedStrategy (advanced)

To use the given MessageCreatedStrategy which are invoked when Camel creates new instances of jakarta.jms.Message objects when Camel is sending a JMS message.

MessageCreatedStrategy

messageIdEnabled (advanced)

When sending, specifies whether message IDs should be added. This is just an hint to the JMS broker. If the JMS provider accepts this hint, these messages must have the message ID set to null; if the provider ignores the hint, the message ID must be set to its normal unique value.

true

boolean

messageListenerContainerFactory (advanced)

Registry ID of the MessageListenerContainerFactory used to determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use to consume messages. Setting this will automatically set consumerType to Custom.

MessageListenerContainerFactory

messageTimestampEnabled (advanced)

Specifies whether timestamps should be enabled by default on sending messages. This is just an hint to the JMS broker. If the JMS provider accepts this hint, these messages must have the timestamp set to zero; if the provider ignores the hint the timestamp must be set to its normal value.

true

boolean

pubSubNoLocal (advanced)

Specifies whether to inhibit the delivery of messages published by its own connection.

false

boolean

receiveTimeout (advanced)

The timeout for receiving messages (in milliseconds).

1000

long

recoveryInterval (advanced)

Specifies the interval between recovery attempts, i.e. when a connection is being refreshed, in milliseconds. The default is 5000 ms, that is, 5 seconds.

5000

long

requestTimeoutCheckerInterval (advanced)

Configures how often Camel should check for timed out Exchanges when doing request/reply over JMS. By default Camel checks once per second. But if you must react faster when a timeout occurs, then you can lower this interval, to check more frequently. The timeout is determined by the option requestTimeout.

1000

long

synchronous (advanced)

Sets whether synchronous processing should be strictly used.

false

boolean

temporaryQueueResolver (advanced)

A pluggable TemporaryQueueResolver that allows you to use your own resolver for creating temporary queues (some messaging systems has special requirements for creating temporary queues).

TemporaryQueueResolver

transferException (advanced)

If enabled and you are using Request Reply messaging (InOut) and an Exchange failed on the consumer side, then the caused Exception will be send back in response as a jakarta.jms.ObjectMessage. If the client is Camel, the returned Exception is rethrown. This allows you to use Camel JMS as a bridge in your routing - for example, using persistent queues to enable robust routing. Notice that if you also have transferExchange enabled, this option takes precedence. The caught exception is required to be serializable. The original Exception on the consumer side can be wrapped in an outer exception such as org.apache.camel.RuntimeCamelException when returned to the producer. Use this with caution as the data is using Java Object serialization and requires the received to be able to deserialize the data at Class level, which forces a strong coupling between the producers and consumer!.

false

boolean

transferExchange (advanced)

You can transfer the exchange over the wire instead of just the body and headers. The following fields are transferred: In body, Out body, Fault body, In headers, Out headers, Fault headers, exchange properties, exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. You must enable this option on both the producer and consumer side, so Camel knows the payloads is an Exchange and not a regular payload. Use this with caution as the data is using Java Object serialization and requires the receiver to be able to deserialize the data at Class level, which forces a strong coupling between the producers and consumers having to use compatible Camel versions!.

false

boolean

useMessageIDAsCorrelationID (advanced)

Specifies whether JMSMessageID should always be used as JMSCorrelationID for InOut messages.

false

boolean

waitForProvisionCorrelationToBeUpdatedCounter (advanced)

Number of times to wait for provisional correlation id to be updated to the actual correlation id when doing request/reply over JMS and when the option useMessageIDAsCorrelationID is enabled.

50

errorHandlerLoggingLevel (logging)

Allows to configure the default errorHandler logging level for logging uncaught exceptions.

Enum values:

  • TRACE

  • DEBUG

  • INFO

  • WARN

  • ERROR

  • OFF

WARN

LoggingLevel

errorHandlerLogStackTrace (logging)

Allows to control whether stack-traces should be logged or not, by the default errorHandler.

true

boolean

password (security)

Password to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory.

String

username (security)

Username to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory.

String

transacted (transaction)

Specifies whether to use transacted mode.

false

boolean

transactedInOut (transaction)

Specifies whether InOut operations (request reply) default to using transacted mode If this flag is set to true, then Spring JmsTemplate will have sessionTransacted set to true, and the acknowledgeMode as transacted on the JmsTemplate used for InOut operations. Note from Spring JMS: that within a JTA transaction, the parameters passed to createQueue, createTopic methods are not taken into account. Depending on the Java EE transaction context, the container makes its own decisions on these values. Analogously, these parameters are not taken into account within a locally managed transaction either, since Spring JMS operates on an existing JMS Session in this case. Setting this flag to true will use a short local JMS transaction when running outside of a managed transaction, and a synchronized local JMS transaction in case of a managed transaction (other than an XA transaction) being present. This has the effect of a local JMS transaction being managed alongside the main transaction (which might be a native JDBC transaction), with the JMS transaction committing right after the main transaction.

false

boolean

lazyCreateTransactionManager (transaction (advanced))

If true, Camel will create a JmsTransactionManager, if there is no transactionManager injected when option transacted=true.

true

boolean

transactionManager (transaction (advanced))

The Spring transaction manager to use.

PlatformTransactionManager

transactionName (transaction (advanced))

The name of the transaction to use.

String

transactionTimeout (transaction (advanced))

The timeout value of the transaction (in seconds), if using transacted mode.

Examples

You’ll need to provide a connectionFactory to the ActiveMQ Component, to have the following examples working.

Producer Example

from("timer:mytimer?period=5000")
        .setBody(constant("HELLO from Camel!"))
        .to("activemq:queue:HELLO.WORLD");

Consumer Example

from("activemq:queue:HELLO.WORLD")
        .log("Received a message - ${body}");

Spring Boot Auto-Configuration

When using activemq with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-activemq-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 112 options, which are listed below.

Name Description Default Type

camel.component.activemq.accept-messages-while-stopping

Specifies whether the consumer accept messages while it is stopping. You may consider enabling this option, if you start and stop JMS routes at runtime, while there are still messages enqueued on the queue. If this option is false, and you stop the JMS route, then messages may be rejected, and the JMS broker would have to attempt redeliveries, which yet again may be rejected, and eventually the message may be moved at a dead letter queue on the JMS broker. To avoid this its recommended to enable this option.

false

Boolean

camel.component.activemq.acknowledgement-mode-name

The JMS acknowledgement name, which is one of: SESSION_TRANSACTED, CLIENT_ACKNOWLEDGE, AUTO_ACKNOWLEDGE, DUPS_OK_ACKNOWLEDGE.

AUTO_ACKNOWLEDGE

String

camel.component.activemq.allow-additional-headers

This option is used to allow additional headers which may have values that are invalid according to JMS specification. For example, some message systems, such as WMQ, do this with header names using prefix JMS_IBM_MQMD_ containing values with byte array or other invalid types. You can specify multiple header names separated by comma, and use as suffix for wildcard matching.

String

camel.component.activemq.allow-auto-wired-connection-factory

Whether to auto-discover ConnectionFactory from the registry, if no connection factory has been configured. If only one instance of ConnectionFactory is found then it will be used. This is enabled by default.

true

Boolean

camel.component.activemq.allow-auto-wired-destination-resolver

Whether to auto-discover DestinationResolver from the registry, if no destination resolver has been configured. If only one instance of DestinationResolver is found then it will be used. This is enabled by default.

true

Boolean

camel.component.activemq.allow-null-body

Whether to allow sending messages with no body. If this option is false and the message body is null, then an JMSException is thrown.

true

Boolean

camel.component.activemq.allow-reply-manager-quick-stop

Whether the DefaultMessageListenerContainer used in the reply managers for request-reply messaging allow the DefaultMessageListenerContainer.runningAllowed flag to quick stop in case JmsConfiguration#isAcceptMessagesWhileStopping is enabled, and org.apache.camel.CamelContext is currently being stopped. This quick stop ability is enabled by default in the regular JMS consumers but to enable for reply managers you must enable this flag.

false

Boolean

camel.component.activemq.allow-serialized-headers

Controls whether or not to include serialized headers. Applies only when transferExchange is true. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level.

false

Boolean

camel.component.activemq.always-copy-message

If true, Camel will always make a JMS message copy of the message when it is passed to the producer for sending. Copying the message is needed in some situations, such as when a replyToDestinationSelectorName is set (incidentally, Camel will set the alwaysCopyMessage option to true, if a replyToDestinationSelectorName is set).

false

Boolean

camel.component.activemq.artemis-consumer-priority

Consumer priorities allow you to ensure that high priority consumers receive messages while they are active. Normally, active consumers connected to a queue receive messages from it in a round-robin fashion. When consumer priorities are in use, messages are delivered round-robin if multiple active consumers exist with the same high priority. Messages will only going to lower priority consumers when the high priority consumers do not have credit available to consume the message, or those high priority consumers have declined to accept the message (for instance because it does not meet the criteria of any selectors associated with the consumer).

Integer

camel.component.activemq.artemis-streaming-enabled

Whether optimizing for Apache Artemis streaming mode. This can reduce memory overhead when using Artemis with JMS StreamMessage types. This option must only be enabled if Apache Artemis is being used.

false

Boolean

camel.component.activemq.async-consumer

Whether the JmsConsumer processes the Exchange asynchronously. If enabled then the JmsConsumer may pickup the next message from the JMS queue, while the previous message is being processed asynchronously (by the Asynchronous Routing Engine). This means that messages may be processed not 100% strictly in order. If disabled (as default) then the Exchange is fully processed before the JmsConsumer will pickup the next message from the JMS queue. Note if transacted has been enabled, then asyncConsumer=true does not run asynchronously, as transaction must be executed synchronously.

false

Boolean

camel.component.activemq.async-start-listener

Whether to startup the JmsConsumer message listener asynchronously, when starting a route. For example if a JmsConsumer cannot get a connection to a remote JMS broker, then it may block while retrying and/or fail-over. This will cause Camel to block while starting routes. By setting this option to true, you will let routes startup, while the JmsConsumer connects to the JMS broker using a dedicated thread in asynchronous mode. If this option is used, then beware that if the connection could not be established, then an exception is logged at WARN level, and the consumer will not be able to receive messages; You can then restart the route to retry.

false

Boolean

camel.component.activemq.async-stop-listener

Whether to stop the JmsConsumer message listener asynchronously, when stopping a route.

false

Boolean

camel.component.activemq.auto-startup

Specifies whether the consumer container should auto-startup.

true

Boolean

camel.component.activemq.autowired-enabled

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

Boolean

camel.component.activemq.broker-url

Sets the broker URL to use to connect to ActiveMQ. If none configured then localhost:61616 is used by default (however can be overridden by configuration from environment variables).

String

camel.component.activemq.browse-limit

Maximum number of messages to keep in memory available for browsing. Use 0 for unlimited.

100

Integer

camel.component.activemq.cache-level

Sets the cache level by ID for the underlying JMS resources. See cacheLevelName option for more details.

Integer

camel.component.activemq.cache-level-name

Sets the cache level by name for the underlying JMS resources. Possible values are: CACHE_AUTO, CACHE_CONNECTION, CACHE_CONSUMER, CACHE_NONE, and CACHE_SESSION. The default setting is CACHE_AUTO. See the Spring documentation and Transactions Cache Levels for more information.

CACHE_AUTO

String

camel.component.activemq.client-id

Sets the JMS client ID to use. Note that this value, if specified, must be unique and can only be used by a single JMS connection instance. It is typically only required for durable topic subscriptions with JMS 1.1.

String

camel.component.activemq.concurrent-consumers

Specifies the default number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToConcurrentConsumers is used to control number of concurrent consumers on the reply message listener.

1

Integer

camel.component.activemq.configuration

To use a shared JMS configuration. The option is a org.apache.camel.component.jms.JmsConfiguration type.

JmsConfiguration

camel.component.activemq.connection-factory

The connection factory to be use. A connection factory must be configured either on the component or endpoint. The option is a jakarta.jms.ConnectionFactory type.

ConnectionFactory

camel.component.activemq.consumer-type

The consumer type to use, which can be one of: Simple, Default, or Custom. The consumer type determines which Spring JMS listener to use. Default will use org.springframework.jms.listener.DefaultMessageListenerContainer, Simple will use org.springframework.jms.listener.SimpleMessageListenerContainer. When Custom is specified, the MessageListenerContainerFactory defined by the messageListenerContainerFactory option will determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use.

ConsumerType

camel.component.activemq.correlation-property

When using InOut exchange pattern use this JMS property instead of JMSCorrelationID JMS property to correlate messages. If set messages will be correlated solely on the value of this property JMSCorrelationID property will be ignored and not set by Camel.

String

camel.component.activemq.default-task-executor-type

Specifies what default TaskExecutor type to use in the DefaultMessageListenerContainer, for both consumer endpoints and the ReplyTo consumer of producer endpoints. Possible values: SimpleAsync (uses Spring’s SimpleAsyncTaskExecutor) or ThreadPool (uses Spring’s ThreadPoolTaskExecutor with optimal values - cached thread-pool-like). If not set, it defaults to the previous behaviour, which uses a cached thread pool for consumer endpoints and SimpleAsync for reply consumers. The use of ThreadPool is recommended to reduce thread trash in elastic configurations with dynamically increasing and decreasing concurrent consumers.

DefaultTaskExecutorType

camel.component.activemq.delivery-delay

Sets delivery delay to use for send calls for JMS. This option requires JMS 2.0 compliant broker.

-1

Long

camel.component.activemq.delivery-mode

Specifies the delivery mode to be used. Possible values are those defined by jakarta.jms.DeliveryMode. NON_PERSISTENT = 1 and PERSISTENT = 2.

Integer

camel.component.activemq.delivery-persistent

Specifies whether persistent delivery is used by default.

true

Boolean

camel.component.activemq.destination-resolver

A pluggable org.springframework.jms.support.destination.DestinationResolver that allows you to use your own resolver (for example, to lookup the real destination in a JNDI registry). The option is a org.springframework.jms.support.destination.DestinationResolver type.

DestinationResolver

camel.component.activemq.disable-reply-to

Specifies whether Camel ignores the JMSReplyTo header in messages. If true, Camel does not send a reply back to the destination specified in the JMSReplyTo header. You can use this option if you want Camel to consume from a route and you do not want Camel to automatically send back a reply message because another component in your code handles the reply message. You can also use this option if you want to use Camel as a proxy between different message brokers and you want to route message from one system to another.

false

Boolean

camel.component.activemq.disable-time-to-live

Use this option to force disabling time to live. For example when you do request/reply over JMS, then Camel will by default use the requestTimeout value as time to live on the message being sent. The problem is that the sender and receiver systems have to have their clocks synchronized, so they are in sync. This is not always so easy to archive. So you can use disableTimeToLive=true to not set a time to live value on the sent message. Then the message will not expire on the receiver system. See below in section About time to live for more details.

false

Boolean

camel.component.activemq.durable-subscription-name

The durable subscriber name for specifying durable topic subscriptions. The clientId option must be configured as well.

String

camel.component.activemq.eager-loading-of-properties

Enables eager loading of JMS properties and payload as soon as a message is loaded which generally is inefficient as the JMS properties may not be required but sometimes can catch early any issues with the underlying JMS provider and the use of JMS properties. See also the option eagerPoisonBody.

false

Boolean

camel.component.activemq.eager-poison-body

If eagerLoadingOfProperties is enabled and the JMS message payload (JMS body or JMS properties) is poison (cannot be read/mapped), then set this text as the message body instead so the message can be processed (the cause of the poison are already stored as exception on the Exchange). This can be turned off by setting eagerPoisonBody=false. See also the option eagerLoadingOfProperties.

Poison JMS message due to ${exception.message}

String

camel.component.activemq.embedded

Use an embedded in-memory (non-persistent) ActiveMQ broker for development and testing purposes. You must have activemq-broker JAR on the classpath.

false

Boolean

camel.component.activemq.enabled

Whether to enable auto configuration of the activemq component. This is enabled by default.

Boolean

camel.component.activemq.error-handler

Specifies a org.springframework.util.ErrorHandler to be invoked in case of any uncaught exceptions thrown while processing a Message. By default these exceptions will be logged at the WARN level, if no errorHandler has been configured. You can configure logging level and whether stack traces should be logged using errorHandlerLoggingLevel and errorHandlerLogStackTrace options. This makes it much easier to configure, than having to code a custom errorHandler. The option is a org.springframework.util.ErrorHandler type.

ErrorHandler

camel.component.activemq.error-handler-log-stack-trace

Allows to control whether stack-traces should be logged or not, by the default errorHandler.

true

Boolean

camel.component.activemq.error-handler-logging-level

Allows to configure the default errorHandler logging level for logging uncaught exceptions.

LoggingLevel

camel.component.activemq.exception-listener

Specifies the JMS Exception Listener that is to be notified of any underlying JMS exceptions. The option is a jakarta.jms.ExceptionListener type.

ExceptionListener

camel.component.activemq.explicit-qos-enabled

Set if the deliveryMode, priority or timeToLive qualities of service should be used when sending messages. This option is based on Spring’s JmsTemplate. The deliveryMode, priority and timeToLive options are applied to the current endpoint. This contrasts with the preserveMessageQos option, which operates at message granularity, reading QoS properties exclusively from the Camel In message headers.

false

Boolean

camel.component.activemq.expose-listener-session

Specifies whether the listener session should be exposed when consuming messages.

false

Boolean

camel.component.activemq.force-send-original-message

When using mapJmsMessage=false Camel will create a new JMS message to send to a new JMS destination if you touch the headers (get or set) during the route. Set this option to true to force Camel to send the original JMS message that was received.

false

Boolean

camel.component.activemq.format-date-headers-to-iso8601

Sets whether JMS date properties should be formatted according to the ISO 8601 standard.

false

Boolean

camel.component.activemq.header-filter-strategy

To use a custom org.apache.camel.spi.HeaderFilterStrategy to filter header to and from Camel message. The option is a org.apache.camel.spi.HeaderFilterStrategy type.

HeaderFilterStrategy

camel.component.activemq.idle-consumer-limit

Specify the limit for the number of consumers that are allowed to be idle at any given time.

1

Integer

camel.component.activemq.idle-receives-per-task-limit

Marks the consumer as idle after the specified number of idle receives have been reached. An idle receive is counted from the moment a null message is returned by the receiver after the potential setReceiveTimeout elapsed. This gives the opportunity to check if the idle task count exceeds setIdleTaskExecutionLimit and based on that decide if the task needs to be re-scheduled or not, saving resources that would otherwise be held. This setting differs from setMaxMessagesPerTask where the task is released and re-scheduled after this limit is reached, no matter if the received messages were null or non-null messages. This setting alone can be inflexible if one desires to have a large enough batch for each task but requires a quick(er) release from the moment there are no more messages to process. This setting differs from setIdleTaskExecutionLimit where this limit decides after how many iterations of being marked as idle, a task is released. For example: If setMaxMessagesPerTask is set to '500' and #setIdleReceivesPerTaskLimit is set to '60' and setReceiveTimeout is set to '1000' and setIdleTaskExecutionLimit is set to '1', then 500 messages per task would be processed unless there is a subsequent number of 60 idle messages received, the task would be marked as idle and released. This also means that after the last message was processed, the task would be released after 60 seconds as long as no new messages appear.

Integer

camel.component.activemq.idle-task-execution-limit

Specifies the limit for idle executions of a receive task, not having received any message within its execution. If this limit is reached, the task will shut down and leave receiving to other executing tasks (in the case of dynamic scheduling; see the maxConcurrentConsumers setting). There is additional doc available from Spring.

1

Integer

camel.component.activemq.include-all-jmsx-properties

Whether to include all JMSX prefixed properties when mapping from JMS to Camel Message. Setting this to true will include properties such as JMSXAppID, and JMSXUserID etc. Note: If you are using a custom headerFilterStrategy then this option does not apply.

false

Boolean

camel.component.activemq.include-correlation-i-d-as-bytes

Whether the JMS consumer should include JMSCorrelationIDAsBytes as a header on the Camel Message.

true

Boolean

camel.component.activemq.include-sent-jms-message-id

Only applicable when sending to JMS destination using InOnly (eg fire and forget). Enabling this option will enrich the Camel Exchange with the actual JMSMessageID that was used by the JMS client when the message was sent to the JMS destination.

false

Boolean

camel.component.activemq.jms-key-format-strategy

Pluggable strategy for encoding and decoding JMS keys so they can be compliant with the JMS specification. Camel provides two implementations out of the box: default and passthrough. The default strategy will safely marshal dots and hyphens (. and -). The passthrough strategy leaves the key as is. Can be used for JMS brokers which do not care whether JMS header keys contain illegal characters. You can provide your own implementation of the org.apache.camel.component.jms.JmsKeyFormatStrategy and refer to it using the # notation.

JmsKeyFormatStrategy

camel.component.activemq.jms-message-type

Allows you to force the use of a specific jakarta.jms.Message implementation for sending JMS messages. Possible values are: Bytes, Map, Object, Stream, Text. By default, Camel would determine which JMS message type to use from the In body type. This option allows you to specify it.

JmsMessageType

camel.component.activemq.lazy-create-transaction-manager

If true, Camel will create a JmsTransactionManager, if there is no transactionManager injected when option transacted=true.

true

Boolean

camel.component.activemq.lazy-start-producer

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

Boolean

camel.component.activemq.map-jms-message

Specifies whether Camel should auto map the received JMS message to a suited payload type, such as jakarta.jms.TextMessage to a String etc.

true

Boolean

camel.component.activemq.max-concurrent-consumers

Specifies the maximum number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToMaxConcurrentConsumers is used to control number of concurrent consumers on the reply message listener.

Integer

camel.component.activemq.max-messages-per-task

The number of messages per task. -1 is unlimited. If you use a range for concurrent consumers (eg min max), then this option can be used to set a value to eg 100 to control how fast the consumers will shrink when less work is required.

-1

Integer

camel.component.activemq.message-converter

To use a custom Spring org.springframework.jms.support.converter.MessageConverter so you can be in control how to map to/from a jakarta.jms.Message. The option is a org.springframework.jms.support.converter.MessageConverter type.

MessageConverter

camel.component.activemq.message-created-strategy

To use the given MessageCreatedStrategy which are invoked when Camel creates new instances of jakarta.jms.Message objects when Camel is sending a JMS message. The option is a org.apache.camel.component.jms.MessageCreatedStrategy type.

MessageCreatedStrategy

camel.component.activemq.message-id-enabled

When sending, specifies whether message IDs should be added. This is just an hint to the JMS broker. If the JMS provider accepts this hint, these messages must have the message ID set to null; if the provider ignores the hint, the message ID must be set to its normal unique value.

true

Boolean

camel.component.activemq.message-listener-container-factory

Registry ID of the MessageListenerContainerFactory used to determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use to consume messages. Setting this will automatically set consumerType to Custom. The option is a org.apache.camel.component.jms.MessageListenerContainerFactory type.

MessageListenerContainerFactory

camel.component.activemq.message-timestamp-enabled

Specifies whether timestamps should be enabled by default on sending messages. This is just an hint to the JMS broker. If the JMS provider accepts this hint, these messages must have the timestamp set to zero; if the provider ignores the hint the timestamp must be set to its normal value.

true

Boolean

camel.component.activemq.password

Password to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory.

String

camel.component.activemq.preserve-message-qos

Set to true, if you want to send message using the QoS settings specified on the message, instead of the QoS settings on the JMS endpoint. The following three headers are considered JMSPriority, JMSDeliveryMode, and JMSExpiration. You can provide all or only some of them. If not provided, Camel will fall back to use the values from the endpoint instead. So, when using this option, the headers override the values from the endpoint. The explicitQosEnabled option, by contrast, will only use options set on the endpoint, and not values from the message header.

false

Boolean

camel.component.activemq.priority

Values greater than 1 specify the message priority when sending (where 1 is the lowest priority and 9 is the highest). The explicitQosEnabled option must also be enabled in order for this option to have any effect.

4

Integer

camel.component.activemq.pub-sub-no-local

Specifies whether to inhibit the delivery of messages published by its own connection.

false

Boolean

camel.component.activemq.queue-browse-strategy

To use a custom QueueBrowseStrategy when browsing queues. The option is a org.apache.camel.component.jms.QueueBrowseStrategy type.

QueueBrowseStrategy

camel.component.activemq.receive-timeout

The timeout for receiving messages (in milliseconds). The option is a long type.

1000

Long

camel.component.activemq.recovery-interval

Specifies the interval between recovery attempts, i.e. when a connection is being refreshed, in milliseconds. The default is 5000 ms, that is, 5 seconds. The option is a long type.

5000

Long

camel.component.activemq.reply-to

Provides an explicit ReplyTo destination (overrides any incoming value of Message.getJMSReplyTo() in consumer).

String

camel.component.activemq.reply-to-cache-level-name

Sets the cache level by name for the reply consumer when doing request/reply over JMS. This option only applies when using fixed reply queues (not temporary). Camel will by default use: CACHE_CONSUMER for exclusive or shared w/ replyToSelectorName. And CACHE_SESSION for shared without replyToSelectorName. Some JMS brokers such as IBM WebSphere may require to set the replyToCacheLevelName=CACHE_NONE to work. Note: If using temporary queues then CACHE_NONE is not allowed, and you must use a higher value such as CACHE_CONSUMER or CACHE_SESSION.

String

camel.component.activemq.reply-to-concurrent-consumers

Specifies the default number of concurrent consumers when doing request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads.

1

Integer

camel.component.activemq.reply-to-consumer-type

The consumer type of the reply consumer (when doing request/reply), which can be one of: Simple, Default, or Custom. The consumer type determines which Spring JMS listener to use. Default will use org.springframework.jms.listener.DefaultMessageListenerContainer, Simple will use org.springframework.jms.listener.SimpleMessageListenerContainer. When Custom is specified, the MessageListenerContainerFactory defined by the messageListenerContainerFactory option will determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use.

ConsumerType

camel.component.activemq.reply-to-delivery-persistent

Specifies whether to use persistent delivery by default for replies.

true

Boolean

camel.component.activemq.reply-to-destination-selector-name

Sets the JMS Selector using the fixed name to be used so you can filter out your own replies from the others when using a shared queue (that is, if you are not using a temporary reply queue).

String

camel.component.activemq.reply-to-max-concurrent-consumers

Specifies the maximum number of concurrent consumers when using request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads.

Integer

camel.component.activemq.reply-to-on-timeout-max-concurrent-consumers

Specifies the maximum number of concurrent consumers for continue routing when timeout occurred when using request/reply over JMS.

1

Integer

camel.component.activemq.reply-to-override

Provides an explicit ReplyTo destination in the JMS message, which overrides the setting of replyTo. It is useful if you want to forward the message to a remote Queue and receive the reply message from the ReplyTo destination.

String

camel.component.activemq.reply-to-same-destination-allowed

Whether a JMS consumer is allowed to send a reply message to the same destination that the consumer is using to consume from. This prevents an endless loop by consuming and sending back the same message to itself.

false

Boolean

camel.component.activemq.reply-to-type

Allows for explicitly specifying which kind of strategy to use for replyTo queues when doing request/reply over JMS. Possible values are: Temporary, Shared, or Exclusive. By default Camel will use temporary queues. However if replyTo has been configured, then Shared is used by default. This option allows you to use exclusive queues instead of shared ones. See Camel JMS documentation for more details, and especially the notes about the implications if running in a clustered environment, and the fact that Shared reply queues has lower performance than its alternatives Temporary and Exclusive.

ReplyToType

camel.component.activemq.request-timeout

The timeout for waiting for a reply when using the InOut Exchange Pattern (in milliseconds). The default is 20 seconds. You can include the header CamelJmsRequestTimeout to override this endpoint configured timeout value, and thus have per message individual timeout values. See also the requestTimeoutCheckerInterval option. The option is a long type.

20000

Long

camel.component.activemq.request-timeout-checker-interval

Configures how often Camel should check for timed out Exchanges when doing request/reply over JMS. By default Camel checks once per second. But if you must react faster when a timeout occurs, then you can lower this interval, to check more frequently. The timeout is determined by the option requestTimeout. The option is a long type.

1000

Long

camel.component.activemq.selector

Sets the JMS selector to use.

String

camel.component.activemq.service-location-enabled

Whether to detect the network address location of the JMS broker on startup. This information is gathered via reflection on the ConnectionFactory, and is vendor specific. This option can be used to turn this off.

true

Boolean

camel.component.activemq.stream-message-type-enabled

Sets whether StreamMessage type is enabled or not. Message payloads of streaming kind such as files, InputStream, etc will either by sent as BytesMessage or StreamMessage. This option controls which kind will be used. By default BytesMessage is used which enforces the entire message payload to be read into memory. By enabling this option the message payload is read into memory in chunks and each chunk is then written to the StreamMessage until no more data.

false

Boolean

camel.component.activemq.subscription-durable

Set whether to make the subscription durable. The durable subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a durable subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well.

false

Boolean

camel.component.activemq.subscription-name

Set the name of a subscription to create. To be applied in case of a topic (pub-sub domain) with a shared or durable subscription. The subscription name needs to be unique within this client’s JMS client id. Default is the class name of the specified message listener. Note: Only 1 concurrent consumer (which is the default of this message listener container) is allowed for each subscription, except for a shared subscription (which requires JMS 2.0).

String

camel.component.activemq.subscription-shared

Set whether to make the subscription shared. The shared subscription name to be used can be specified through the subscriptionName property. Default is false. Set this to true to register a shared subscription, typically in combination with a subscriptionName value (unless your message listener class name is good enough as subscription name). Note that shared subscriptions may also be durable, so this flag can (and often will) be combined with subscriptionDurable as well. Only makes sense when listening to a topic (pub-sub domain), therefore this method switches the pubSubDomain flag as well. Requires a JMS 2.0 compatible message broker.

false

Boolean

camel.component.activemq.synchronous

Sets whether synchronous processing should be strictly used.

false

Boolean

camel.component.activemq.task-executor

Allows you to specify a custom task executor for consuming messages. The option is a org.springframework.core.task.TaskExecutor type.

TaskExecutor

camel.component.activemq.temporary-queue-resolver

A pluggable TemporaryQueueResolver that allows you to use your own resolver for creating temporary queues (some messaging systems has special requirements for creating temporary queues). The option is a org.apache.camel.component.jms.TemporaryQueueResolver type.

TemporaryQueueResolver

camel.component.activemq.test-connection-on-startup

Specifies whether to test the connection on startup. This ensures that when Camel starts that all the JMS consumers have a valid connection to the JMS broker. If a connection cannot be granted then Camel throws an exception on startup. This ensures that Camel is not started with failed connections. The JMS producers is tested as well.

false

Boolean

camel.component.activemq.time-to-live

When sending messages, specifies the time-to-live of the message (in milliseconds).

-1

Long

camel.component.activemq.transacted

Specifies whether to use transacted mode.

false

Boolean

camel.component.activemq.transacted-in-out

Specifies whether InOut operations (request reply) default to using transacted mode If this flag is set to true, then Spring JmsTemplate will have sessionTransacted set to true, and the acknowledgeMode as transacted on the JmsTemplate used for InOut operations. Note from Spring JMS: that within a JTA transaction, the parameters passed to createQueue, createTopic methods are not taken into account. Depending on the Java EE transaction context, the container makes its own decisions on these values. Analogously, these parameters are not taken into account within a locally managed transaction either, since Spring JMS operates on an existing JMS Session in this case. Setting this flag to true will use a short local JMS transaction when running outside of a managed transaction, and a synchronized local JMS transaction in case of a managed transaction (other than an XA transaction) being present. This has the effect of a local JMS transaction being managed alongside the main transaction (which might be a native JDBC transaction), with the JMS transaction committing right after the main transaction.

false

Boolean

camel.component.activemq.transaction-manager

The Spring transaction manager to use. The option is a org.springframework.transaction.PlatformTransactionManager type.

PlatformTransactionManager

camel.component.activemq.transaction-name

The name of the transaction to use.

String

camel.component.activemq.transaction-timeout

The timeout value of the transaction (in seconds), if using transacted mode.

-1

Integer

camel.component.activemq.transfer-exception

If enabled and you are using Request Reply messaging (InOut) and an Exchange failed on the consumer side, then the caused Exception will be send back in response as a jakarta.jms.ObjectMessage. If the client is Camel, the returned Exception is rethrown. This allows you to use Camel JMS as a bridge in your routing - for example, using persistent queues to enable robust routing. Notice that if you also have transferExchange enabled, this option takes precedence. The caught exception is required to be serializable. The original Exception on the consumer side can be wrapped in an outer exception such as org.apache.camel.RuntimeCamelException when returned to the producer. Use this with caution as the data is using Java Object serialization and requires the received to be able to deserialize the data at Class level, which forces a strong coupling between the producers and consumer!.

false

Boolean

camel.component.activemq.transfer-exchange

You can transfer the exchange over the wire instead of just the body and headers. The following fields are transferred: In body, Out body, Fault body, In headers, Out headers, Fault headers, exchange properties, exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. You must enable this option on both the producer and consumer side, so Camel knows the payloads is an Exchange and not a regular payload. Use this with caution as the data is using Java Object serialization and requires the receiver to be able to deserialize the data at Class level, which forces a strong coupling between the producers and consumers having to use compatible Camel versions!.

false

Boolean

camel.component.activemq.trust-all-packages

Define if all Java packages are trusted or not (for Java object JMS message types). Notice its not recommended practice to send Java serialized objects over network. Setting this to true can expose security risks, so use this with care.

false

Boolean

camel.component.activemq.use-message-id-as-correlation-id

Specifies whether JMSMessageID should always be used as JMSCorrelationID for InOut messages.

false

Boolean

camel.component.activemq.use-pooled-connection

Enables or disables whether a PooledConnectionFactory will be used so that when messages are sent to ActiveMQ from outside a message consuming thread, pooling will be used rather than the default with the Spring JmsTemplate which will create a new connection, session, producer for each message then close them all down again. The default value is true.

true

Boolean

camel.component.activemq.use-single-connection

Enables or disables whether a Spring SingleConnectionFactory will be used so that when messages are sent to ActiveMQ from outside a message consuming thread, pooling will be used rather than the default with the Spring JmsTemplate which will create a new connection, session, producer for each message then close them all down again. The default value is false and a pooled connection is used by default.

false

Boolean

camel.component.activemq.username

Username to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory.

String

camel.component.activemq.wait-for-provision-correlation-to-be-updated-counter

Number of times to wait for provisional correlation id to be updated to the actual correlation id when doing request/reply over JMS and when the option useMessageIDAsCorrelationID is enabled.

50

Integer

camel.component.activemq.wait-for-provision-correlation-to-be-updated-thread-sleeping-time

Interval in millis to sleep each time while waiting for provisional correlation id to be updated. The option is a long type.

100

Long

camel.component.activemq.wait-for-temporary-reply-to-to-be-updated-counter

Number of times to wait for temporary replyTo queue to be created and ready when doing request/reply over JMS.

200

Integer

camel.component.activemq.wait-for-temporary-reply-to-to-be-updated-thread-sleeping-time

Interval in millis to sleep each time while waiting for temporary replyTo queue to be ready. The option is a long type.
