I guess i was a bit paranoid about this. I'm sorry! When you unsubscribe the topic, as I said before, all the message references are removed. You could also use the method removeAllMessages on the MBean Topic if that applies. You also have a method listAllSubscriptions on the Topic MBean where you could validate your current subscription. Does that cover what you want to achieve? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4158793#...
