sample hello world application

[narasimha]

I am a beginner. I want to start with a hello world application.
at this point i made the following :
a>business interface
b>bean
c>test client


a>firstInterface.java

package server;

import javax.ejb.Remote;

@Remote
public interface firstInterface
{
public String hello();

}

b>firstBean.java

package server;

import javax.ejb.Remote;
import javax.ejb.Stateless;

@ Stateless
@ Remote(firstInterface.class)
public class firstBean implements firstInterface
{

public String hello()
{
System.out.println("hello()");
return "hello world !";
}
}


c>firstTestClient.java

package client;

import javax.naming.Context;
import javax.naming.InitialContext;
import server.firstInterface;

public class firstTestClient {

/**
* @param args
* @throws Exception
*/
public static void main(String[] args) throws Exception
{
// TODO Auto-generated method stub
Context ctx = new InitialContext();

firstInterface fInterface = (firstInterface) ctx.lookup("server/firstInterface");
System.out.println(fInterface.hello());
}

}



i have no idea as what to do further. I do not know the flow. for instance what all xml files do i need to generate and esentially how do i deploy the bean.

i realy appreciate if you guys could help me out.

thank you.
