Hi Adrian, Thanks for the explanation on the problem. I will give it a try for that patch. Could I know where should I get it? Will the solution you suggested (update the redelivery status prior the msg delivery to the client) be applied to the latest Jboss AS also? or it is a temporary solution to resolve my case? In the jira, I saw the fix version will be in JBossAS-5.0.0.Beta3 and JBossAS-4.2.3.GA. Does it mean I need to update my current jboss to the latest version after the official patch make available? Or will you provide a seperate patch for JBoss 4.0.5 GA? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4096661#...
