javax.naming.NameNotFoundException: While trying to lookup

[Dave Robinson]

I am writing a test client for my ejb and I am getting an exception while trying to do a lookup. I am thinking that my ejb-jar.xml or weblogic-ejb-jar.xml is not configured properly or my value I am passing for the lookup is not correct.

Context ctx = getInitialContext();
      DemoHome dhome = (DemoHome) 
        ctx.lookup("demo.Demo");

static public Context getInitialContext() 
      throws Exception {
    Properties p = new Properties();
    p.put(Context.INITIAL_CONTEXT_FACTORY,
      "weblogic.jndi.T3InitialContextFactory");
    p.put(Context.PROVIDER_URL, url);
    if (user != null) {
      System.out.println ("user: " + user);
      p.put(Context.SECURITY_PRINCIPAL, user);
      if (password == null)
        password = "";
      p.put(Context.SECURITY_CREDENTIALS, password);
    }
    return new InitialContext(p);
  }

Someone please advise

Hi

I hope the JNDI name in the Deployment descriptor(ejb.demo.Demo.DemoBean) and the one you are trying to lookup are different (Demo.DemoBean). Try with full JNDI name. Since i am not very sure of weblogic. Since in JBoss it requires full JNDI name.
