EJB Exception (Accesing a remote enterprise bean within a simple Java class)

[John Wenn]

Here's my Java class

import endpoint.NewSessionRemote;
import javax.naming.Context;
import javax.naming.InitialContext;

public class HelloClient {

    public static void main(String[] args) {
        try {
            Context ctx = new InitialContext();
            NewSessionRemote hello = (NewSessionRemote) ctx.lookup("endpoint.NewSessionRemote");
            System.out.println(hello.stringChange(4));
        } catch (Exception ex) {
            ex.printStackTrace();
        }

    }
}

When I run this I'm getting an exception

javax.naming.NameNotFoundException: endpoint.NewSessionRemote not found

All the other enterprise bean classes are written according to the EJB 3.0 standard. Your valuable contribution is expected.
I'm using Glassfish v3 + NetBeans 6.1

How have you mapped the session bean, implementing the NewSessionRemote interface, jndi name, 'endpoint.NewSessionRemote' ? Are you using annotations or are you using the ejb-jar or web.xml to map to jndi?
