[jboss-user] [JBoss Messaging] - Re: Poss solution frequent deadlocks on SQLServer

What does an MDB container do here? Yes, this is probably because Spring isn't enlisting the session in the JTA transaction until after it has received the message from JBM using a message listener. Either that or there is a small period of time between Spring delisting the session from the JTA tx before commit and enlisting it in the next one, when a message can be received but the session is not enlisted. The session is therefore not transacted at that point so acts as auto_ack and acks immediately. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4104470#...
