Hi, I am new at EJB and i read Head First EJB.I use Windows XP,J2EE Reference Implementation and J2SDK 1.4.2.When i tried to run the first example and specifically the client (AdviceClient) the following message was displayed:
E:\source\projects\advice>java AdviceClient
Context Created!!!
javax.naming.NoInitialContextException: Need to specify class name in environmen
t or system property, or as an applet parameter, or in an application resource f

at AdviceClient.go(
at AdviceClient.main(

import javax.naming.*;

import headfirst.*;
import javax.ejb.*;

public class AdviceClient
public static void main(String[] args)
new AdviceClient().go();
public void go() {
Context ic = new InitialContext();
System.out.println("Context Created!!!");
Object o = ic.lookup("Advisor");
System.out.println("Lookup DONE!!!");
AdviceHome home = (AdviceHome) PortableRemoteObject.narrow(o, AdviceHome.class);
System.out.println("Narrowing DONE!!!");
Advice advisor = home.create();
System.out.println("Remote Object Created!!!");
catch (Exception ex)

Now from the message i think that somewhere i must specify the properties of InitialContext.Am i right and if i am where and how can i do this? Kathy,Bert HELP please!
