Stand-alone JNDI lookup of an EJB in an Enterprise Application (EAR) build

Question

Hi All,
I am having some difficulty doing JNDI look up an EJB 3.0 Bean that is part of an Enterprise Application (EAR) build. Below are all the related codes:
package ejb;
import javax.ejb.Local;
@Local
public interface Hello1Local {
    public String getHello1();
package ejb;
import javax.ejb.Stateless;
@Stateless
public class Hello1Bean implements Hello1Local {
    public String getHello1() {
        return "I am Hello1 Bean!";
package ejb;
import javax.ejb.Remote;
@Remote
public interface Hello2Remote {
    public String getHello2();
package ejb;
import javax.ejb.Stateless;
import javax.ejb.EJB;
@Stateless
@EJB(name="ejb/Hello1",
     beanInterface=Hello1Local.class,
     beanName="Hello1Bean")
public class Hello2Bean implements Hello2Remote {
    @EJB private Hello1Local hello1bean;
    public String getHello2() {
        return hello1bean.getHello1();
There is no problem looking up Hello2 Bean using an Application Client such as the following:
public class LocalHelloApplicationClient {
    @EJB(name="Hello2")
    private static Hello2Remote hello2Bean;
    public static void main(String[] args) {
        System.out.println("hello2Bean.getHello2(): " + hello2Bean.getHello2());
}There is also no problem doing JNDI lookup (from a Stand-Alone Client the same bean if both Hello1 and Hello2 were created by themselves. ie not part of an Enterprise Application (EAR) build. However, I am wondering whether it is possible to do JNDI lookup of the same bean (Hello2) that is part of an Enterprise Application (EAR) built. Below are the type of JNDI lookup entries that I have tried without success:
public class StandalonePojoCallHelloWorld {
    public static void main(String [] args)
        try
            InitialContext jndiContext = new InitialContext();
            Hello2Remote hello2Bean =  (Hello2Remote) jndiContext.lookup("ejb.Hello2Remote");
                                                                 or
            Hello2Remote hello2Bean =  (Hello2Remote) jndiContext.lookup("LocalHelloEnterpriseApplication.Hello2.remote");
                                                                 or
            Hello2Remote hello2Bean =  (Hello2Remote) jndiContext.lookup("LocalHelloEnterpriseApplication.ejb.Hello2Remote");
                                                                 or
            Hello2Remote hello2Bean =  (Hello2Remote) jndiContext.lookup("LocalHelloEnterpriseApplication.Hello2Remote");
                                                                 or
            Hello2Remote hello2Bean =  (Hello2Remote) jndiContext.lookup("LocalHelloEnterpriseApplication.LocalHelloEnterpriseApplication-ejb.Hello2Remote");
            System.out.println("hello2Bean.getHello2(): " + hello2Bean.getHello2());
        catch (javax.naming.NamingException ne)
         ne.printStackTrace();
They all came up with the same error message:
javax.naming.NameNotFoundException: LocalHelloEnterpriseApplication.LocalHelloEnterpriseApplication-ejb.Hello2Remote not found
        at com.sun.enterprise.naming.TransientContext.doLookup(TransientContext.java:216)
        at com.sun.enterprise.naming.TransientContext.lookup(TransientContext.java:188)

        at java.lang.reflect.Method.invoke(Method.java:597)Any suggestion would be appreciated.
Thanks,

Hello
I've somme problems to get access to ejb interface from remote stand-alone client.
Here is my EJB code :
package stateless;
import javax.ejb.Stateless;
@Stateless(name = "TestSB", mappedName = "ejb/stateless/TestSB")
public class TestEJBBean implements TestEJBRemote {
    public String getMessage() {
       return "Hello EJB World";
}And the remote interface :
package stateless;
import javax.ejb.Remote;
@Remote
public interface TestEJBRemote {
    String getMessage();
} In client side, i just edit main.java like this :
package testclient;
import java.io.FileInputStream;
import java.util.Properties;
import javax.naming.InitialContext;
import stateless.TestEJBRemote;
public class Main {
    public static void main(String[] args) throws Exception {
        Properties props = new Properties();
        props.load(new FileInputStream("jndi.properties"));
        InitialContext ctx = new InitialContext(props);
        TestEJBRemote testEJB = (TestEJBRemote) ctx.lookup("ejb/stateless/TestSB");
        System.out.println(testEJB.getMessage());
}here is my jndi.properties file (my glassfish server IP is 192.168.0.10) :
java.naming.factory.initial = com.sun.enterprise.naming.SerialInitContextFactory
java.naming.factory.url.pkgs = com.sun.enterprise.naming
java.naming.factory.state = com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl
org.omg.CORBA.ORBInitialHost = 192.168.0.10
org.omg.CORBA.ORBInitialPort = 3918when i run client on the same machine than the glassfish app server, it works fine.
But i run it on the different machine than the glassfish app server (on the same LAN without firewall), it fails with this error message :
