You're right. I had not properly removed the OpenJMS libraries from the app classpath. Once I did that, I was able to deliver messages to the queue. However, now my listener is not registering. I am attempting to register my Message Listener by setting it to my MessageConsumer; which is set by casting my queue from JNDI into a javax.jms.Destination. Any ideas as to why my listener is not working? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3983989#...
