Thanks! You don't need to download anything apart from the app server. If you are using JBoss 5, JBoss Messaging is an integral part of the app server, there's no need to install anything else, it's already there. Download JBoss AS 5, create a standard MDB, deploy it, and you are *already* using JBM. JBM is the default JMS provide in JBoss AS 5.0 Hope that helps :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4135752#...
