Hi Arun, JBM 1.4.3.GA is for AS 5.1. 1.4.1.GA is the right one. JBM 1.4 (not 2.0) always needs a db to work with. However, if you don't use cluster, the default DB is well pre-configured and ready to use. So you don't need to worry about it. Have a look at deploy/messaging/destinations-service.xml, you need to configure your queue in this file. For the rest of your questions, I think you'd better read the document thru. It may take you some time but it would well deserve your time. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4217272#...
