Java SE6 client for EJB - Error in lookup

[Nancy Antony]

I create a Remote Stateless session Bean with the following simple code

package hello;

import javax.ejb.Remote;

@Remote
public interface SayHelloRemote {
    public String sayHelloToAll();
}

And Class Implementation is :

package hello;

import javax.ejb.Stateless;

@Stateless
public class SayHello implements SayHelloRemote {
    
    // Add business logic below. (Right-click in editor and choose
    // "Insert Code > Add Business Method")
    public String sayHelloToAll(){
        return "Hello to All Java/JEE developers...";
    }
}

And I wrote a Java SE Client as follows:

package allworld;
import javax.naming.Context;
import javax.naming.InitialContext;
import hello.*;

public class TestBeanSaysHello {
    public static void main(String[] args) {
        try{
            Context ctx = new InitialContext();
             SayHelloRemote sayHello = (SayHelloRemote)ctx.lookup("java:global/HelloBean/SayHelloRemote");
            String s= sayHello.sayHelloToAll();
            System.out.println("Bean Says :"+s);
        }catch(Exception e){
            System.out.println("Exception executing Bean : "+e);
        }
       
    }

}

I added HelloBean Project in library and gf-client.jar from glassfish modules. When I run this I get :

Nov 9, 2011 8:02:58 AM com.sun.enterprise.transaction.JavaEETransactionManagerSimplified initDelegates
INFO: Using com.sun.enterprise.transaction.jts.JavaEETransactionManagerJTSDelegate as the delegate

and it keeps running infinitely

Can anyone help?

You should rather lookup:

SayHelloRemote sayHello = (SayHelloRemote)ctx.lookup("java:global/HelloBean/SayHello");  

or

SayHelloRemote sayHello = (SayHelloRemote)ctx.lookup("java:global/HelloBean/SayHello!hello.SayHelloRemote");  

Despite that - what Application Server are you using?

[Nancy Antony]

I tried the suggestions, but it didn't work.

I got this stack trace : I'm using Glassfish 3.1

Any help ?

[Piotr Nowicki]

Do you have any ejb-jar.xml attached to your app?
Does Glassfish reports (i.e. in logs) what JNDI names does it give to your EJBs?

EDIT: is this a fresh Glassfish or some modified version (already configured)?

[James Boswell]

Hi Nancy

Can I ask why you are using "java:global/HelloBean/SayHelloRemote" to look up your bean? I cannot see a reference to anything by the name of HelloBean.

Assuming you have not configured the JNDI name of the bean separately, I think your lookup name should simply be "SayHello/remote".

[Piotr Nowicki]

The HelloBean is the application/module name.

Nancy

It might be worth looking here.

I wasn't aware but it looks like the JNDI name depends on how your application is packaged and deployed on GF.
