We are trying to use the push functionality of RF 3.3.3 with a message driven bean. We are getting stuck trying to make our managed bean that the a4j:push points to also receive messages. We are deployed in a war in JBoss 4.2.3. Are there any known limitations on using MDBs in WAR deployments? Based on the developer's guide the combination of these two technologies is suggested, but we can't seem to get it working end to end.
