Hi, I'm seeing this behavior on jboss 4.0.1. We have an MDB that listens for jms messages of a topic, so that messages are processed using the MDB's onMessage() method (as is standard usage). We found however that if the jms service is restarted (e.g. by touching the jms service.xml file to cause jms services to be redeployed), then even though our sender program recovers, all messages that are sent after the recovery do not trigger any MDB actions, it's as though no MDBs are triggered at all. To cause MDBs to work again, I actually have to redeploy the ear file. I dont' think this is acceptable behavior. What am I missing?
