Ganesh, Looking at the logs i dont see the UserSession bean getting deployed. Can you post the ejb-jar.xml that you are deploying (i do see that you have already posted one, but is it the one you are using for deploying - it does not look correct). Also, post the output of the following command from the command prompt: - Go to C:\devTools\jboss-4.0.1\jboss-4.0.1\server\default\deploy from the command prompt - Run the following command: jar -tf mfsc.ear View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4047309#...
