ejb3 hello world on was7

[vik ar]

Hi. I am new to ejb3 so please bear with me. I have successfully deployed and started an ear to WAS 7 which contains a jar containing the following two classes:

package com.mybiz.server;

import javax.ejb.Local;

@Local
public interface HelloWorld {
    public String getMessage();
}

package com.mybiz.server;

import javax.ejb.Stateless;

@Stateless
public class HelloWorldImpl implements HelloWorld {
    public String getMessage() { 
        return "Hello World";
    }
}   

I then developed the following client class

package com.mybiz.client;

import javax.ejb.EJB;
import com.mybiz.server.HelloWorld;

public class Client  {
    private @EJB HelloWorld hello;
    public static void main(String[] args) {
    	Client client = new Client();
        client.doTest();
        
    }
    
    public void doTest(){
    	System.out.println(hello.getMessage());
    }
}

When I execute the client the hello object is null? Can someone please explain what the next step is for me to successfully execute the client. thanks

Right when I said I executed my client what I meant was I right clicked the class in eclipse and selected run as java application. I have since come to realise its not this simple!!! After reading here I realised I needed to package my client class into a jar file and then into a ear file. My ant script is as follows:

<target name="makeear">

		<ear earfile="${build}/jar/HelloWorldServer.ear" appxml="${build}/META-INF/application.xml">
			<fileset dir="${build}/jar">
				<include name="HelloWorldServer.jar" />
			</fileset>
		</ear>

		<ear earfile="${build}/jar/HelloWorldClient.ear" appxml="${build}/META-INF/application-client.xml">
			<fileset dir="${build}/jar">
				<include name="HelloWorldClient.jar" />
			</fileset>
		</ear>

</target>    

Within HelloWorldClient.ear the application-client.xml is present but it has been renamed application.xml??? Also what should the contents of the application-client.xml be?

Please see here for an update. The lack of resources on the net for developing a simple ejb3 hello world app on was is startling!!!
