Cache coordination with tomcat 6 [message #1403418]

Hello,

I'm trying to use EclipseLink cache coordination within my tomcat 6 application. I'm using activeMQ which already works find in my environment. In my server.xml I've defined the following Resources:

 <Resource
        auth="Container"
        brokerURL="tcp://jms:61616?daemon=true"
        description="JMS Connection Factory"
        factory="org.apache.activemq.jndi.JNDIReferenceFactory"
        name="jms/connectionFactory"
        type="org.apache.activemq.ActiveMQConnectionFactory"
    />
    <Resource
        description="Change Notification Topic"
        factory="org.apache.activemq.jndi.JNDIReferenceFactory"
        name="jms/changeNotification"
        physicalName="T.SERVICE.INT"
        type="org.apache.activemq.command.ActiveMQTopic"
    />

And my persistence.xml looks like this:

<property name="eclipselink.cache.coordination.protocol" value="jms" />
<property name="eclipselink.cache.coordination.jms.topic" value="jms/changeNotification" />
<property name="eclipselink.cache.coordination.jms.factory" value="jms/jmsConnectionFactory" />

If I startup my tomcat I get the following exception:

[EL Warning]: 2014-07-23 16:19:35.146--ServerSession(1669472530)--Exception [EclipseLink-22103] (Eclipse Persistence Services - 2.4.1.v20121003-ad44345): org.eclipse.persistence.exceptions.RemoteCommandManagerException
Exception Description: Could not look up remote connection under name jms/jmsConnectionFactory with URL null
Internal Exception: javax.naming.NameNotFoundException: Name jms is not bound in this Context

Any ideas what's wrong? Is it possible with tomcat anyways? Could not find any information about it in the www. Smile

Greetings,

Ok, small update. This did the trick inside the persistence.xml

<property name="eclipselink.cache.coordination.jms.topic" value="java:comp/env/jms/changeNotification" />
<property name="eclipselink.cache.coordination.jms.factory" value="java:comp/env/jms/connectionFactory" />

But... it seems EclipseLink is not sending any notifications via JMS. I can't see the cache coordination working in my logging.

Any assistance? Smile

It seems that EclipseLink JMS Connection is established but EclipseLink is not sending any sync messages. Entities are configured correctly I guess:

@Cacheable(true)
@Cache(type = CacheType.FULL, coordinationType = CacheCoordinationType.SEND_NEW_OBJECTS_WITH_CHANGES)

If I send a text message manually via activeMQ EclipseLink is responding in my logging with:

[EL Warning]: 2014-07-24 11:20:24.706--ServerSession(992328659)--Received unexpected message type: org.apache.activemq.command.ActiveMQTextMessage from topic: T.SERVICE.INT; ignoring

So it seems EclipseLink is listening via JMS, but why isn't it sending any sync messages?

Sascha
