How to run a client in j2ee

Question

Hi Guys,
I have successfully created a bean and deployed it in J2EE server. My next step according to the head first ejb is to create a client. I compiled AdviceClient successfully (Thanks to grava). However when I try to run the compiled class I get the following error:
C:\projects\advice>java AdviceClient
javax.naming.CommunicationException: Can't find SerialContextProvider
at com.sun.enterprise.naming.SerialContext.getProvider(SerialContext.jav
a:63)
at com.sun.enterprise.naming.SerialContext.lookup(SerialContext.java:120
at javax.naming.InitialContext.lookup(InitialContext.java:350)
at AdviceClient.go(AdviceClient.java:16)
at AdviceClient.main(AdviceClient.java:10)
Could you please tell me what is going on?
The following is the class ActiveClient:
import javax.naming.*;
import java.rmi.*;
import headfirst.*;
import javax.rmi.*;
import javax.ejb.*;
public class AdviceClient{
public static void main (String[] args){
new AdviceClient().go();
public void go(){
try{
Context ic=new InitialContext();
Object o=ic.lookup("Advisor");
AdviceHome home=(AdviceHome) PortableRemoteObject.narrow(o, AdviceHome.class);
Advice advisor=home.create();
System.out.println(advisor.getAdvice());
}catch (Exception ex){
ex.printStackTrace();
Kind regards,
Al

Hi,
When running client, in my previous attempts, the j2ee server was not running. However when I run the server the following error messages appear:
C:\projects\advice>java AdviceClient

I appreciate any attempts to solve this problem.
