My code is

package com.nabil.ejb;

import javax.ejb.MessageDrivenBean;
import javax.ejb.MessageDrivenContext;
import javax.ejb.EJBException;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.Queue;

import javax.jms.QueueConnectionFactory;
import javax.jms.QueueSender;
import javax.jms.QueueSession;
import javax.jms.TextMessage;
import javax.naming.InitialContext;
import javax.naming.NamingException;


public class MyMDB implements MessageDrivenBean, MessageListener {
 MessageDrivenContext context = null;
 QueueConnection connection;
 QueueSession session;

 public MyMDB() {
 System.out.println("Constructing MyMDB");
 }

 public void setMessageDrivenContext(MessageDrivenContext context) {
 this.context = context;
 System.out.println("setMessageDrivenContext");
 }

 public void ejbCreate() throws EJBException {
 System.out.println("ejbCreate");
 try {
 InitialContext initContext = new InitialContext();
 QueueConnectionFactory qcf = (QueueConnectionFactory)
 initContext.lookup("java:comp/env/jms/QCF");
 connection = qcf.createQueueConnection();
 session = connection.createQueueSession(false, QueueSession.AUTO_ACKNOWLEDGE);
 connection.start();
 }
 catch(Exception e) {
 throw new EJBException("Failed to initialize MyMDB", e);
 }
 }

 public void ejbRemove() {
 System.out.println("ejbRemove");
 context = null;
 try {
 if( session != null )
 session.close();
 if( connection != null )
 connection.close();
 }
 catch(JMSException e) {
 e.printStackTrace();
 }
 }

 public void onMessage(Message msg) {
 System.out.println("onMessage");
 try {
 TextMessage message = (TextMessage) msg;
 Queue queue = (Queue) msg.getJMSReplyTo();
 QueueSender sender = session.createSender(queue);
 TextMessage message2 = session.createTextMessage(message.getText());
 sender.send(message2);
 sender.close();
 }
 catch(Exception e) {
 e.printStackTrace();
 }
 }
}
