      Hi

      Im using EJB3 with Jboss-4.0.4.GA app server. I have deployed an ear file containing -jar file -> a stateless session bean,
      and war file -> servlet.

      In the servlet class when I look up the bean. The look up is successful, but when I cast it to bean interface the following exception is thrown.
