Jboss Error

[javahpk]

I get this error whenever I try to run my (client) HelloClient.class file using Jboss 3.0 final

javax.naming.NoInitialContextException: Cannotinstantiateclass:org.jnp.interfaces.NamingContextFactory
[Root exception is java.lang.ClassNotFoundException: o
rg.jnp.interfaces.NamingContextFactory]


Any idea what might be causing this error and how to get rid of ?
==============
The code for HelloClient.java is
import javax.naming.*;
import javax.ejb.*;
import java.rmi.*;
import javax.rmi.*;

public class HelloClient {

public static void main(String[] args) {
try {
InitialContext ict= new InitialContext();
Object obj= ict.lookup("Hello");

HelloHome home= (HelloHome)
PortableRemoteObject.narrow(obj, HelloHome.class);

Hello hello= home.create();
hello.sayHello();
System.out.println(hello.getInfo());
}
catch(Exception ex){
System.out.println(ex);
}
}

}

You need to have the required jar files in your class path. For client programs, these can be found in the client library of jboss.

In order to access the jboss server u need some jboss jars in your classpath. to be sure put all the jars from ${jboss}/client/ in your classpath (u don't really need the all)
