Hi, It is working after server restart, my assumption on jboss was that, we need not restart the server, just create a ejb jar again and deploy. Meanwhile, just as every ejb3 beginner, even i have a doubt on calling stateful session bean, the example given for stateful works fine..but it gives the same result when i change the bean to stateless..I think Client.java is not the correct method to test the stateful session beans example. I believe we need to use a servlet, i tried that too, but same result Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4199255#...
