EJB with jboss 4

Running EJB (EJB 2) with jboss (jboss 4) requires some setup. I am trying to explain the steps one needs to for EJB to work with jboss .
File 1 :- MyTestSession.java

package ejbs.sessionBeans;

import java.rmi.RemoteException;

import javax.ejb.EJBObject;

public interface MyTestSession extends EJBObject{
 public String sayHello() throws RemoteException;
}

File 2 :- MyTestSessionHome.java

package ejbs.sessionBeans;

import java.rmi.RemoteException;
import java.sql.SQLException;

import javax.ejb.EJBException;
import javax.naming.NamingException;


public interface MyTestSessionHome extends javax.ejb.EJBHome{
 public MyTestSession create() throws javax.ejb.CreateException,EJBException, RemoteException, NamingException;
 
} 

File 3 :- MyTestSessionBean.java

package ejbs.sessionBeans;

import java.rmi.RemoteException;
import javax.ejb.EJBException;
import javax.ejb.EJBHome;
import javax.ejb.EJBObject;
import javax.ejb.Handle;
import javax.ejb.RemoveException;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public class MyTestSessionBean implements SessionBean {

 @Override
 public void ejbActivate() throws EJBException, RemoteException {
  System.out.println("In  ejbActivate()");
 }

 @Override
 public void ejbPassivate() throws EJBException, RemoteException {
  System.out.println("In  ejbPassivate()");
 }

 @Override
 public void ejbRemove() throws EJBException, RemoteException {
  System.out.println("In  ejbRemove()");
 }

 @Override
 public void setSessionContext(SessionContext arg0) throws EJBException,
   RemoteException {
  System.out.println("In setSessionContext");
 }
 
 public String sayHello() throws RemoteException{
  return "Alll";  
 }

 public void ejbCreate() throws javax.ejb.CreateException,EJBException, RemoteException, NamingException {
               System.out.println("In ejbCreate()");
  
 }

}

Now we require enter the details of this Session Bean in two XML files . One in the ejb-jar.xml and jboss.xml .
File 4 :- ejb-jar.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise
JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd">
<ejb-jar>
 <display-name>MyFirstSessionBean</display-name>
 <description>My First Session bean description</description>
 <enterprise-beans>
  <session>
   <display-name>MySessionBean</display-name>
   <ejb-name>ejbs/sessionBeans/MyTestSession</ejb-name>
   <home>ejbs.sessionBeans.MyTestSessionHome</home>
   <remote>ejbs.sessionBeans.MyTestSession</remote>
   <ejb-class>ejbs.sessionBeans.MyTestSessionBean</ejb-class>
   <session-type>Stateless</session-type>
   <transaction-type>Container</transaction-type>
  </session>
 </enterprise-beans>
</ejb-jar>

File 5 :- jboss.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBoss//EN"
"http://www.jboss.org/j2ee/dtd/jboss.dtd">
<jboss>
 <enterprise-beans>
  <session>
   <ejb-name>ejbs/sessionBeans/MyTestSession</ejb-name>
   <jndi-name>ejb/MyTestSession</jndi-name>
  </session>
 </enterprise-beans>
</jboss>

Now in any of your servlet call the following java lines.

  InitialContext ctx = new InitialContext();
  Object objref = ctx.lookup("ejb/MyTestSession");
  MyTestSessionHome myTestSessionHome = (MyTestSessionHome)PortableRemoteObject.narrow(objref,MyTestSessionHome.class);
   MyTestSession myTestSession=  myTestSessionHome.create();
   String receivedString = myTestSession.sayHello();
System.out.println(receivedString);
