How to enable transaction with activemq camel component

Question

While consuming message from JMS queue I wish to decide whether consuming process is success or fail, In case of failure I wish that activemq redeliver the message again after some time like 1 minute. Later on based on delivery count I may send it to DLQ.

I found examples to achieve same with java code like session with different acknowledgement mode or making the session transacted but could not get how to achieve same with blueprint file.

If you haven't done so already, read through this chapter to learn more about how JMS XA Transactions work in JBoss Fuse.

You're missing the Spring PlatformTransactionManagerand a few other things. Here's an example of a configuration that should work:

<!-- Service reference to Spring’s PlatformTransactionManager -->
<reference id=”osgiPlatformTransactionManager”
    interface=”org.springframework.transaction.PlatformTransactionManager”>

<!-- Service reference to JTA TransactionManager -->
<reference id=”osgiJtaTransactionManager”
    interface=”javax.transaction.TransactionManager”>

<!-- JMS TX endpoint -->
<bean id=”activemq” class=”org.apache.activemq.camel.component.ActiveMQComponent”>
    <property name=”configuration” ref=”jmsTxConfig”>
</bean>

<bean id=”jmsTxConfig” class=”org.apache.camel.component.jms.JmsConfiguration”>
    <property name=”connectionFactory” ref=”jmsXaPoolConnectionFactory” />
    <property name=”transactionManager” ref=”osgiPlatformTransactionManager” />
    <!-- transacted must be set to “false” for XA transactions -->
    <!-- as it is only meant to be used with local transactions -->
    <property name=”transacted” value=”false” />
</bean>

<!-- The connection factory wrapper to enable auto-enlisting -->
<bean id=”jmsXaPoolConnectionFactory”
    class=”org.apache.activemq.pool.JcaPooledConnectionFactory”>
    <property name=”name” value=”MyXaResource” />
    <property name=”maxConnections” value=”1” />
    <property name=”connectionFactory” ref=”jmsXaConnectionFactory” />
    <property name=”transactionManager” ref=”osgiJtaTransactionManager” />
</bean>

<bean id=”jmsXaConnectionFactory”
    class=”org.apache.activemq.ActiveMQXAConnectionFactory”>
    <property name=”brokerURL” value=”${activemq.url}” />
    <property name=”userName” value=”${activemq.user}” />
    <property name=”password” value=”${activemq.password}” />
    <property name="watchTopicAdvisories" value="false" />
    <property name="redeliveryPolicy" >
    <bean class="org.apache.activemq.RedeliveryPolicy" >
        <property name="maximumRedeliveries" value="0" />
    </bean>
</property>
</bean>

<!-- ActiveMQ XA Resource Manager -->
<bean id=”resourceManager” class=”org.apache.activemq.pool.ActiveMQResourceManager”
    init-method=”recoverResource”>
    <property name=”transactionManager” ref=”osgiJtaTransactionManager” />
    <property name=”connectionFactory” ref=”jmsXaConnectionFactory” />
    <property name=”resourceName” value=”activemq.default” />
</bean>

<!-- Transaction Policy to be referenced by the transacted-component in a route -->
<bean id=”txPolicy” class=”org.apache.camel.spring.spi.SpringTransactionPolicy”>
    <property name=”transactionManager” ref=”osgiPlatformTransactionManager” />
    <!-- PROPAGATION_REQUIRED is the default value if a behavior is not set -->
    <property name=”propagationBehaviorName” value=”PROPAGATION_REQUIRED” />
</bean>
