Hello guys.
If you have an environment like mine and you were stuck for days
with trying to run the client......... i found the solution!
Windows XP
1.3.1 jdk2ee
j2sdk 1.4.2_03
The solution has to do with how you configure the CLASSPATH and what is the command to compile and run the client.
The source is as in the HF EJB book but instead of getAvice() i use getMessage() which i do not know if it helps!( I will test it with getAdvice() later) I also have added some comments for debugging purposes. Take a look:
import javax.naming.*;
import java.rmi.*;
import javax.rmi.*;
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)
1)Your CLASSPATH environmental variable should include the path to j2ee.jar and also to the advice directory like this:
2)To compile the client you type the following from advice directory:
javac -classpath %CLASSPATH%;%CLASSPATH%\AdviceAppClient.jar
3)To run the client you type the following from advice directory:
java -classpath %CLASSPATH%;%CLASSPATH%;\AdviceAppClient.jar AdviceClient
That's all folks. I hope that will help you.
Ooh i can't stop running the client.....everytime a different message is displayed............he he

If you are using the RI, this bug will cause problems with the "getAdvice()" method

oh and not to forget...if you have any program running like Norton Internet Security you should disable it because it prevents the client to run and a bunch of exceptions appear from nowhere

ok......... there is an error in the command to run the client. Instead of :
java -classpath %CLASSPATH%;%CLASSPATH%;\AdviceAppClient.jar AdviceClient
java -classpath %CLASSPATH%;%CLASSPATH%\AdviceAppClient.jar AdviceClient
I agree. Here's the link:
