I am using Apache Camel and camel-amqp component in order to communicate with an ASB queue.
<bean id="jmsConnectionFactory" class="org.apache.qpid.jms.JmsConnectionFactory">
<property name="remoteURI" value="amqps://${service.bus.uri}?amqp.idleTimeout=120000" />
<property name="username" value="${service.bus.username}" />
<property name="password" value="${service.bus.password}" />
<property name="receiveLocalOnly" value="true" />
</bean>
<bean id="jmsCachingConnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">
<property name="targetConnectionFactory" ref="jmsConnectionFactory" />
</bean>
<bean id="jmsConfig" class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="jmsCachingConnectionFactory"/>
<property name="cacheLevelName" value="CACHE_CONSUMER"/>
</bean>
...
<route>
...
<to uri="amqp:queue:{{service.bus.queue}}?exchangePattern=InOnly"/>
</route>
The first time that my route is running a AmqpFixedProducer is created for the {{service.bus.queue}}. If i manage to re-run the route (after 10 minutes) then I am getting the following error:
Caused by: javax.jms.JMSException: The link 'G24:360891:qpid-jms:sender:ID:b60452dd-5a2e-4478-a462-7ca280ecd953:1:2:1:themis-test' is force detached by the broker due to errors occurred in publisher(link252).

It seems that application uses the same producer for both calls bu the connection to the ASB is closed after 10 minutes.
My question is how can I manage this?
Is there a way to retrieve the producer that was automatically created by Camel, and an OnException part close it and retry again? How can I get the producer?
Thanks a lot!
Problem was solved by modifying cacheLevelName to CACHE_NONE instead of CACHE_CONSUMER.
<bean id="jmsConfig" class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="jmsCachingConnectionFactory"/>
<property name="cacheLevelName" value="CACHE_NONE"/>
</bean>
