Clustering-test problem.

[Goran Markovic]

Hi, I was trying to perform some clustering in Jboss. I am guided by 'Jboss in Action" book, and its examples.
I am trying to perform clustering in EJB following the instruction from the book. I deploy two node as described in the book and start client. I get this exception :

java.lang.ClassCastException: javax.naming.Reference cannot be cast to com.manning.jbia.Counter

This the client code:

package com.manning.jbia;

import java.util.Hashtable;

import javax.naming.Context;
import javax.naming.InitialContext;

public class Client {
	public static void main(String[] args) throws Exception {
		Hashtable<String, String> properties = new Hashtable<String, String>();
		properties.put(Context.INITIAL_CONTEXT_FACTORY,
				"org.jnp.interfaces.NamingContextFactory");
		properties.put(Context.URL_PKG_PREFIXES, "org.jboss.naming");
		properties.put(Context.PROVIDER_URL, "192.168.1.140:1100,192.168.1.141:1100");
		
		InitialContext ctx = new InitialContext(properties);
try{
	
		Counter s = (Counter) ctx.lookup("CounterBean/remote");

		for (int i = 0; i < 100; i++) {
			s.printCount(i);
			Thread.sleep(1000);
		}
		
}catch (Exception e){
	e.printStackTrace();
}
	}
}

Where do I getting wrong?
Thanks!

Hi. But when I checked about an Object retrieved from address

		Object o =  ctx.lookup("CounterBean/remote");
		System.out.println(o);

I get this :
