Ciao a tutti,

Premetto che sono alle prime armi con gli EJB. Ho creato un EJB SESSION con ecplise e come application server JBOSS v. (jboss-4.2.2.GA) usando XDOCLET V1.2.3.

Ho creato una classe Main e il tutto mi funziona correttamente. Il mio problema sta quando creo un progetto di tipo "Dynamic web Project". In sostanza ho creato una servlet dove chiamo un metodo dell'interfaccia Remota. Quando provo a lanciare la servlet mi genera il seguente errore ERROR [LogInterceptor] EJBException in method: public abstract
Di seguito il codice della mia servlet e i 2 file web.xml e jboss-web.xml che si trovano dentro la cartella WEB-INF del progetto web.

Classe Servlet:

package com.ejb;

import java.io.IOException;
import java.rmi.RemoteException;
import java.util.Properties;

import javax.ejb.CreateException;
import javax.ejb.RemoveException;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.rmi.PortableRemoteObject;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

La servlet funziona solo se cancello le interfaccie dall'EAR.
Qualcuno sa dirmi come posso fare? è una settimana che ci stò sbattendo la testa ma risultati "0".
Vi ringrazio in aticipo!!!
