one step ahead!

I created the .ear ( EARShop ) that "uses" both the .jar ( BookShop ) and the .war ( WebShop ).
I removed the .jar from the WEB-INF/lib inside the .war ( because during .ear deploy there was a duplicate name error ); to include my beans in my web project i simply added under its properties, to the JavaBuildPath/Projects, my BookShop project.

now while deploying the .ear i can read this:

that means i should lookup my ejbs with this name:
+EARShop/OperazioniUtenti/local+
( EAR_NAME/bean/local, not JAR_NAME/bean/local );
i tried it and i found out that it doesn't work; instead it works if i use: 
+          EARShop/OperazioniUtenti/local-bookshop.library.sessionbean.OperazioniUtentiLocal+

Why are there 2 jndi binding, non-default and default, and here i need to use the default while testing my .jar i use the non-default?


A problem however still persist in the lookup procedure:

+opUser = (OperazioniUtenti) context.lookup("EARShop/OperazioniUtenti/local-bookshop.library.sessionbean.OperazioniUtentiLocal");+

+12:37:47,753 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/WebShop].[somethingServlet]] Servlet.service() for servlet somethingServlet threw exception: java.lang.ClassCastException: $Proxy330 cannot be cast to bookshop.library.sessionbean.OperazioniUtenti+

+          at javax.servlet.http.HttpServlet.service(HttpServlet.java:754) [:1.0.0.Final]+
bla bla bla

Do you know how to solve it?

Thank you a lot and sorry for bothering you so much!!!
