Camel ActiveMQ connection creates lots of null transaction commits

Solution Verified - Updated -

Issue

  • We have noticed in our environment that we get a lot of DEBUG level messages like.
2014-06-20 16:57:03,820 | DEBUG | Camel (Process) thread #205 - JmsConsumer[QUEUE.TestQueue] | ActiveMQSession      | 176 - org.apache.activemq.activemq-core - 5.7.0.fuse-71-047 | ID:3216-1403297317359-39:1:6 Transaction Commit :null

2014-06-20 16:57:03,820 | DEBUG | Camel (Process) thread #205 - JmsConsumer[Queue.TestQueue] | ActiveMQSession      | 176 - org.apache.activemq.activemq-core - 5.7.0.fuse-71-047 | ID:33216-1403297317359-39:1:15 Transaction Rollback, txid:null
  • While everything is working correctly, we believe we might be using transactions with Spring and ActiveMQ in camel incorrectly causing null transactions to created and committed continually.

  • Below is our spring for creating the activemq bean for camel. Is this correct/best?

<bean class="org.apache.activemq.pool.PooledConnectionFactory" id="jmsConnectionFactory">
        <property name="connectionFactory">
          <bean class="org.apache.activemq.ActiveMQConnectionFactory">
            <property name="brokerURL">
              <value>${activeMQServer}</value>
            </property>
            <property name="userName">
              <value>${activeMQServerUserName}</value>
            </property>
            <property name="password">
              <value>${activeMQServerPassword}</value>
            </property>
          </bean>
        </property>
    </bean>


    <bean name="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent">
        <property name="connectionFactory" ref="jmsConnectionFactory"></property>
        <property name="transactionManager" ref="transactionManager"></property>
        <property name="transacted" value="true"></property>
        <property name="cacheLevelName" value="CACHE_CONSUMER"></property>
    </bean>



    <bean id="transactionManager" class="org.springframework.jms.connection.JmsTransactionManager">
        <property name="connectionFactory" ref="jmsConnectionFactory"></property>
    </bean>

  <bean id="PROPAGATION_REQUIRED" class="org.apache.camel.spring.spi.SpringTransactionPolicy">
    <property name="transactionManager" ref="transactionManager"></property>
  </bean>
