[jboss-user] [JBoss Messaging] - Integrating Websphere MQ with JBoss

[ejb3workshop]

I have deployed the JCA Resource Adaptor for Websphere MQ on JBoss and able to pull messages of a queue. However currently the MQ hostname is configured either via annotations as shown below. Since I also specify these setting in the wmq.jmsra-ds.xml file (see below) I was hoping to proxy the MQQueue and access it as an standard jms destination. This would allow me to keep my code and descriptors separate from the MQ configuration (Queue Manager, Hostname, Port etc).  However trying this I got 

anonymous wrote : 
  | java.lang.ClassCastException: com.ibm.mq.jms.MQQueue cannot be cast to org.jboss.jms.destination.JBossDestination
  |         at org.jboss.jms.client.container.SessionAspect.handleCreateConnectionConsumer(SessionAspect.java:737)
  |         at org.jboss.aop.advice.org.jboss.jms.client.container.SessionAspect1.invoke(SessionAspect1.java)

After adding the reference to the resource adaptor used (wmq.jmsra.rar) back in, this problem disappeared, but it ask for the MQ configuration again. Ideally I would like to configure the MQ Queue / ConnectionFactory in the application server and access it from my application as a standard JMS destination. This would allow me to keep my code portable.

If you have any suggestion on how this can be achieved, please let me know.

Thanks in advance
Alex
