Ejb3 -Accessing Local Enterprise Beans Using the No-Interface View - ejb-3.1

Question

I'm trying to learn EJB3,
I created an EJB project with just a bean class:
package com;
import javax.ejb.Local;
import javax.ejb.Stateless;
#Stateless
#LocalBean
public class MyBean {
public MyBean() {
// TODO Auto-generated constructor stub
}
public String getMessage(){
return "Hello";
};
}
I deployed this project on Jboss 6 , then i create a Java project (adding in the build path the ejbProject above and Jboss-client.jar to make RMI calls).
for testing , this is the class i created:
import javax.ejb.EJB;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import com.MyBean;
public class LanceProgram {
// #EJB
//public static MyBean mybean;
public static void main(String[] args) {
Context ctx;
try {
ctx = new InitialContext();
MyBean exampleBean = (MyBean) ctx.lookup("MyBean");
System.out.println(exampleBean.getMessage());
} catch (NamingException e) {
e.printStackTrace();
}
}
}
Normally, when running this, i should have a reference to MyBean,but it's null and i have this error message (using JNDI lookup):
Exception in thread "main" java.lang.ClassCastException: org.jnp.interfaces.NamingContext cannot be cast to com.MyBean
at LanceProgram.main(LanceProgram.java:17)
While with an EJB injection i have a NullPointerException !
this i my jndi.properties file specifications:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=localhost:1099
java.naming.factory.url.pkgs=org.jboss.ejb.client.naming
I'm trying to make a call to a bean which doesn't implements an interface.
Thanks for helping
