HI Peter, I have able to have my application running, thanks for your valuable suggestions. I had missed to include jboss-hibernate.deployer which we had in jboss4.0.2 into jboss-4.2.2 custom servers. The only problem that remains is Web service. As Jboss 4.0.2 had jboss-ws4ee.sar and this has been replaced with jbossws.sar in Jboss-4.2.2. I have been looking for details as to do have to do some modification to use jbossws or we can still use jboss-ws4ee instead of jbossws.sar in jboss4.2.2. Please let me know if have some details about this. Thanking you in advance. Regards Amit Sharma View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4162012#...
