Glassfish v3 / JNDI-Eintrag kann nicht gefunden werden Probleme!

Ich habe Probleme versuchen, Aufruf einer EJB-Methode aus einer Java-Anwendung Client.
Hier ist der code.

EJB-Remote-Interface

package com.test;

import javax.ejb.Remote;

@Remote
public interface HelloBeanRemote {

    public String sayHello();

}

EJB

package com.test;

import javax.ejb.Stateless;

@Stateless (name="HelloBeanExample" , mappedName="ejb/HelloBean")
public class HelloBean implements HelloBeanRemote {

    @Override
    public String sayHello(){

        return "hola";

    }

}

Hauptklasse (ein anderes Projekt)

import com.test.HelloBeanRemote;
import javax.naming.Context;
import javax.naming.InitialContext;

public class Main {


    public void runTest()throws Exception{

        Context ctx = new InitialContext();
        HelloBeanRemote  bean = (HelloBeanRemote)ctx.lookup("java:global/Test/HelloBeanExample!com.test.HelloBeanRemote");
        System.out.println(bean.sayHello());

    }


    public static void main(String[] args)throws Exception {

        Main main = new Main();
        main.runTest();

    }

}

Na, was ist mein problem? JNDI-Eintrag für diese EJB können nicht gefunden werden!

Habe ich versucht mit verschiedenen JNDI-Einträge, aber nichts funktioniert (ich habe diese Einträge von NetBeans Konsole):

INFO: Portable JNDI-Namen EJB-HelloBeanExample : [java:global/Test/HelloBeanExample, java:global/Test/HelloBeanExample!com.test.HelloBeanRemote]

INFO: Glassfish-spezifische (Nicht-portable) - JNDI-Namen EJB-HelloBeanExample : [ejb/HelloBean, ejb/HelloBean#com.test.HelloBeanRemote]

Also versuchte ich mit den folgenden Einträgen, aber ich habe die gleiche Ausnahme :

1. java:global/Test/HelloBeanExample
2. java:global/Test/HelloBeanExample!com.test.HelloBeanRemote
3. ejb/HelloBean
4. ejb/HelloBean#com.test.HelloBeanRemote

Ich bin mit Netbeans 6.8 und Glassfish v3!
