Hi Adrian, thanks a lot for your reply. Let me brief about my environment. I am using JBoss 4.2.1 and we are trying to connect to "IBM MQ 5.2". Documentation on the wiki is stating that it supports only 5.3 and above. It is really appreciated if you could provide any guidance/help on "how to communicate from JBoss 4.2.1 to IBM MQ 5.2". Thanks a lot VVK View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4125307#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
