I am using JBoss MQ with MDBs. In my code, I catch an exception and call setRollbackOnly. I am using JTA via spring to manage transactions. I see that my database transactions were rolled back; however, my JMS message seems to disappear. I was expecting it to be redelivered to my queue and the processing to try again. Here are some of my configurations... my-jboss-mq.xml file <depends optional-attribute-name="DestinationManager"> jboss.mq:service=DestinationManager 10 10 ejb-jar.xml <message-driven> <ejb-name>CellularOutgoingMDB</ejb-name> <ejb-class>fn.service.ejb.CellularOutgoingMDB</ejb-class> <transaction-type>Bean</transaction-type> <acknowledge-mode>Auto-acknowledge</acknowledge-mode> <message-driven-destination> <destination-type>javax.jms.Queue</destination-type> </message-driven-destination> ...more stuff.. </message-driven> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3963061#...
