      Hi,

      I am new to jboss world and i m currently having some problems deploying EJB in jboss.


      Problem:
      I have written an entity bean and have deployed it. I am alble to view that in the GLOBAL NAMESPACE of JNDI View. I tried creating a client to the EJB within the same EJB project which is nothing but a java class and it worked fine. Now when i am trying to create another web client to call the same deployed entity bean then i m getting the following exception:




      Exception:
