Java EE (Java Enterprise Edition) General Discussion

Hi

I'm new to Websphere. I deployed a session bean in Websphere. I have written a client program too. Client is unable to connect to the server.

Is there any particular sequence of steps which we should folllow so that the client program can connect to server successfully. If anybody knows those steps please help me.

I'm pasting the Client code below.

thanx
Ramu

package naveen;

import java.io.*;
import java.util.*;
import javax.naming.*;

public class HelloClient{


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

System.out.println("Hello Client Main Method Called...");
Hashtable h=new Hashtable();

h.put(Context.PROVIDER_URL,"iiop:///");
h.put(Context.INITIAL_CONTEXT_FACTORY,"com.ibm.websphere.naming.WsnInitialContextFactory");
System.out.println("Hello Client before context intialization...");

Context ctxt=new InitialContext(h);

System.out.println("Hello Client after context initialization...");

Object o=ctxt.lookup("HelloJndi");

HelloHome hh=(HelloHome)o;

HelloRemote hr=hh.create();

System.out.println(hr.sayHello());
}
}

This program's output is it's printing "Before context intialization"
After that error message

I am giving that error message also:
