Hi all,
I have a slight problem, I try to create a reference Stateless SessionBean but
for some reason each time my client tries to access the Bean after looking it
up on JNDI I end up getting the following exception:
| Exception in thread "main" java.lang.NoClassDefFoundError:

Here is my source:
Remote Interface:
| package com.kimbasoft.reference.ejb.session;
|
| public interface TestRemote {
|
| public String sayHelloRemote();
|
| }
|
Local Interface:
| package com.kimbasoft.reference.ejb.session;
|
| public interface TestLocal {
|
| public String sayHelloLocal();
|
| }
|
Bean Implementation:
| package com.kimbasoft.reference.ejb.session;
|
| import javax.ejb.Remote;
| import javax.ejb.Stateless;
| import javax.ejb.Local;
|
| @Stateless
| @Local({TestLocal.class })
| @Remote({TestRemote.class})
| public class TestBean implements TestRemote {
|
| public String sayHelloRemote() {
| return "Hello Remote World!!!";
| }
|
| public String sayHelloLocal() {
| return "Hello Local World!!!";
| }
|
| }
|
Client Implementation:
| package com.kimbasoft.reference.ejb.client;
|
| import com.kimbasoft.reference.ejb.session.TestRemote;
|
| import javax.naming.Context;
| import javax.naming.InitialContext;
| import javax.naming.NamingException;
|
| public class MyClient {
|
|
| public static void main(String[] args) {
|
| Context ctx;
|
| try {
| ctx = new InitialContext();
| TestRemote obj = (TestRemote) ctx.lookup("TestBean/remote");
| System.out.println(">>" + obj.sayHelloRemote());
| } catch (NamingException e) {
| System.out.println("ERROR");
| e.printStackTrace();
| }
|
| }
| }
|
First I compile everything and package it into a JAR file. Then I deploy it on
JBoss. After deploying I check the JNDI content and can see my TestBean and
it's remote and local interface. Now I start the client (I have the client JARs
of JBoss in the path) on my local pc out of a local copy of the JAR file I
deployed on the server and then I get the above mentioned exception. Can
anybody help me and tell me what I'm doing wrong???
Thanks,
Kimba
Configuration:
JBoss 4.0.4 GA
jboss-EJB-3.0_RC8-FD
JDK 1.5.0
