    I can't lookup EJB (3.0) in WebLogic 12 using ENC


      I have a simple application divided in 2 modules:

      • HolaMundo - Servlet component
      • SimpleEJB - EJB Component


      The EJB Component use EJB 3.0. I created a local business interface with one method. A stateless EJB that implement that interface. And I use the ejb-jar.xml for declare it.

      And a Servlet that use the EJB.


      In Glassfish or Tomee this way for working with EJB works, but i don't understand why it doesn't work in WebLogic 12...


      When i try to access to the servlet, i get an error. this is the error:



      javax.naming.NameNotFoundException: While trying to look up /app/SimpleEJB/Example!com.edwin.ejb.ExampleLocal in /app/webapp/HolaMundo.war/1051995086.; remaining name '/app/SimpleEJB/Example!com/edwin/ejb/ExampleLocal'

      package servlet;
      import java.io.IOException;
      import java.io.PrintWriter;
      import javax.naming.InitialContext;
      import javax.naming.NamingException;
      import javax.servlet.ServletException;
      import javax.servlet.http.HttpServlet;
      import javax.servlet.http.HttpServletRequest;
      import javax.servlet.http.HttpServletResponse;
      import com.edwin.ejb.ExampleLocal;
      public class EJB extends HttpServlet {
         private static final long serialVersionUID = 1L;
         protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1)
         throws ServletException, IOException {
         PrintWriter out = arg1.getWriter();
         ExampleLocal el2;
         try {
        el2 = (ExampleLocal) new InitialContext()
         out.println("EJBBBB: " + el2.nombre());
         } catch (NamingException e) {


      Local business interface:


      package com.edwin.ejb;
      public interface ExampleLocal {
          public String nombre();

      EJB Stateless:


      package com.edwin.ejb;
      public class Example implements ExampleLocal{
          public String nombre() {
              return "Edwin";
