Tim, But my aplication has a time interval when we check Queue and each verification is a new session. If I apply rollback in a Session s1, according with you another software has created session s2 and it will be consumes the message again, thats right ? Or if I shutdown my application I'll close the current session and start again my application a new session will be created. So when a start again my application must be consumes all messages stored in table ? Regards. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4043769#...
