Hi all, I am trying to shut down server when message producer is sending messages and message consumer is listening to the same queue. I want that message producers and message consumers automatically reconnect to the message server once it start again, so I set the method to reconnect after getting exception. The reconnect procedure is simple. It creates new connection, session and procedure, then it connects to the same queue. The problem is some messages are duplicated in message consumer. I used persitent delivery mode, so I expect to get no duplication. Any help regarding this problem will be appreciated Regards, Hendra This is my testing environment : Server : jboss 4.0.4 GA Jboss-Messaging : 1.0.1 RC4 Session : non-transacted, auto acknowledge Delivery mode : persistent View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3973521#...
