*I'm very beginner in ejb programming so please don't be angry if the question is easy.*
*Below is a code I wrote and it produces an error. What should I change to get this to work? I work with Eclipse Juno and JBoss 7.1.1. Below example should work for* 
Application Server - JBoss 4.2.2 GA
IDE - Eclipse 3.4.1
*It doesn't work for my environment. Any help will be appreciated.*
