[Ravendra Singh]

Hi,

I'm trying to run Head First EJB - Advice example. I've created and deployed the bean using RI but when when I tried to run AdviceClient class, I'm getting the below error.

Please find below my client java code and the error message

Please help.

AdviceClient.java

import javax.naming.*;
import java.rmi.*;
import javax.rmi.*;
import javax.ejb.*;

import rksejb.*;

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 (RemoteException rex) {
			rex.printStackTrace();
		} catch (CreateException cex) {
			cex.printStackTrace();
		} catch (Exception ex) {
			ex.printStackTrace();
		}
	}
}

The class (JDKBridge) that wasn't being found can be found in:

C:\j2sdk1.4.2_08\jre\lib\rt.jar

After adding that to my classpath, the program worked fine.

Why are you using such ancient Java versions? JEE 1.3 and JSE 1.4 (from your directory names) have been replaced ages ago. JEE 6 and 7 are now mainstream, as well as JSE 7 (with 8 already released).
