EJB3 and jboss4.0.3SP1 jndi exception from standalone progra

[delkant]

Hi. i have the next problem,
i have one ejb3 Test.class with the next code:
Server side

package my.pkg.ejb;

import javax.ejb.Remote;
import javax.ejb.Stateful;

@Stateful
@Remote
public class Test {
 public String getTest(){
 return "the big test";
 }
}

and then i have also my Client

Test

package py.pkg.client.jnditest;
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;

import my.pkg.Test;
public class Test
 {

 /**
 * @param args
 */
 public static void main(String[] args)
 {
 try{
 Properties prop = new Properties();
 prop.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
 prop.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
 prop.put(Context.PROVIDER_URL, "jnp://localhost:1099");
 //Use them to get the context
 Context context = new InitialContext(prop);
 Object ref = context.lookup(Test.class.getName());
 Test p = (Test)PortableRemoteObject.narrow(ref, Test.class);
 System.out.println("lookup(test): " + p.getTest());
 }
 catch (Exception e)
 {
 System.out.println("Exception "+e);
 e.printStackTrace();
 }
 }

 }

i put also in my classpath the jbossall-client.jar, the ejb3 class.

but when i run my test client.. i get the next ERRROR
