weblogic ed ejb

**n1o** · 21-06-2010, 13:23

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:

codice:

guardando all'interno del progetto

ho visto il file weblogic-ejb-jar.xml che è praticamente vuoto e contiene solamente:

Codice PHP:


<?xml version="1.0" encoding="UTF-8"?>

<weblogic-ejb-jar xmlns="http://www.bea.com/ns/weblogic/90"/>

questa è la mia servlet:

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);

        }

dove sbaglio?

grazie in anticipo per l'aiuto

ho fatto delle piccole modifiche nel persistence.xml ed adesso mi lancia questa eccezione:

codice:

anche se devo dire che mi vede i miei entity ad esempio:

codice:

 
21-giu-2010 14.32.57 org.hibernate.cfg.annotations.QueryBinder bindQuery
INFO: Binding Named query: Dbusers.findById => SELECT d FROM Dbusers d WHERE d.id = :id

dove sbaglio?
avete qualche idea o suggerimento da darmi?
