Hello i have want to try EJB 3.0 but i have problems.
the problem is this i have EJB 3.0 like this :
package beans;

import javax.ejb.Stateless;

@Stateless(name="SimpleSession")
public class SimpleSessionBean implements SimpleSession {
  public SimpleSessionBean() {
  }

  public String sayHello(String name) {
    return "Hello "+name;
  }
}

package beans;

import javax.ejb.Remote;

@Remote
public interface SimpleSession {
public String sayHello(String name) ;
}


and i make test client for it .

  package client;

import beans.SimpleSession;

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

public class SimpleSessionClient {
  public static void main(String[] args) {
    InitialContext ctx;
    try {
       

       ctx = new InitialContext();
       ctx.addToEnvironment("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
        ctx.addToEnvironment("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
       ctx.addToEnvironment(Context.PROVIDER_URL,"jnp://localhost:1099");
    SimpleSession simpleSession
    = (SimpleSession) ctx.lookup(SimpleSession.class.getName());
    System.out.println(simpleSession.sayHello("EJB3"));
    } catch (NamingException e) {
       e.printStackTrace();
    }
  }
}


but when i delpoy the EJB and start the client i get :
cannot find : org.jboss.naming:org.jnp.interfaces
Nothink UNNORAML
i add to the CLASSPATH everythink in jbossServer/client/*.jars
when i start now i get :
