[jboss-user] [Security & JAAS/JBoss] - Getting Exception while trying to access a Stateless EJB in

[dvuday]

Hi...

I am trying to access a Stateless EJB 
I am getting an Exception when trying to access the EJB which is deployed in the jboss server.

==========================================
The client program from which I tried to access is :
==========================================
package client;

import java.util.Properties;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;

import examples.ejb21.Hello;
import examples.ejb21.HelloHome;

public class HelloClient
{
	public static void main (String args[])throws Exception
	{
		Properties props = new Properties();
		
props.put(Context.INITIAL_CONTEXT_FACTORY,"org.jboss.naming.HttpNamingContextFactory");
props.put(Context.PROVIDER_URL,"jnp://localhost:8080");
			Context ctx = new InitialContext(props);
			Object obj = ctx.lookup("HelloHome");
			HelloHome home = (HelloHome)PortableRemoteObject.narrow(obj, HelloHome.class);
			Hello hello = home.create();
			
			System.out.println(hello.hello());
			
			hello.remove();		
	}
}

=============================================================================================
The Exception I got is 

javax.naming.NamingException: Failed to retrieve Naming interface [Root exception is java.io.StreamCorruptedException: invalid stream header]
	at org.jboss.naming.HttpNamingContextFactory.getInitialContext(HttpNamingContextFactory.java:69)

========================================================================

Can anybody help me to come out of this Exception??
