Nam is correct.
If you want to use the local interface, put the web and ejb modules in a
J2EE application so that the web project will have a context for calling
the EJB. You can also change the EJB to have a Remote interface.
btw, if you used Netbeans when invoking the EJB from the web project:
(right click on source, then invoke Enterprise Resources->Call
Enterprise Bean), it will guide you through these "rules".
Thanks.
