Stateless Session Bean Example



June 4, 2012 at 12:04 PM


Yes sir,

I'm working on this example and getting error that I've give above. I wonder there is no jboss.xml file in this project where jndi references are given.

Note: I didn't change any thing in this project. Just download and run.

Please help me as I'm new to EJB.
