Salve a tutti ragazzi,
sto iniziando un nuovo progetto su server oracle weblogic, ho fatto una classe di prova per vedere se tutto andava a buonfine ma purtroppo mi da questa eccezione quando da pagina jsp richiamo la servlet:

session.AmbientiFacade_ubmhka_AmbientiFacadeLocalImpl.findAll(AmbientiFacade_ubmhka_AmbientiFacadeLocalImpl.java:310) ... 40 more
ho visto il file weblogic-ejb-jar.xml che è praticamente vuoto e contiene solamente:
questa è la mia servlet:Codice PHP:<?xml version="1.0" encoding="UTF-8"?>
<weblogic-ejb-jar xmlns="http://www.bea.com/ns/weblogic/90"/>
dove sbaglio?Codice PHP:public class FindAllAmbiente_srv extends HttpServlet {
@EJB
private ControllerDaoLocal controllerDao;
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {
List elenco = (List) controllerDao.findAllAmbienti();
Iterator i = elenco.iterator();
request.setAttribute("elencoAmbienti", i);
request.getRequestDispatcher("/lista_ambienti.jsp").forward(request, response);
}
grazie in anticipo per l'aiuto
