Right way to do JMS Application with MDB and Glassfish 3 - ejb

Question

I am new to JMS and I Wrote a Wrote a sender and receiver and it has worked fine . Now i want a MDB to be used for this. I have googled a lot for this but did not find any good website so i am summering the way i wrote. Please correct me if i am wrong and
This is not completely working so i think there is something wrong in my code.
Sender:
public class MySender {
/**
* #param args
*/
public static void main(String[] args) {
try
{ //Create and start connection
Hashtable hashTable = new Hashtable();
hashTable.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.enterprise.naming.impl.SerialInitContextFactory");
hashTable.put(Context.URL_PKG_PREFIXES, "com.sun.enterprise.naming");
hashTable.put(Context.PROVIDER_URL, "http://localhost:4848");
//1) Create and start connection
InitialContext ctx=new InitialContext(hashTable);
QueueConnectionFactory f=(QueueConnectionFactory)ctx.lookup("myQueueConnectionFactory");
QueueConnection con=f.createQueueConnection();
con.start();
//2) create queue session
QueueSession ses=con.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
//3) get the Queue object
Queue t=(Queue)ctx.lookup("myQueue");
//4)create QueueSender object
QueueSender sender=ses.createSender(t);
//5) create TextMessage object
//5) create TextMessage object
TextMessage msg=ses.createTextMessage();
msg.setText("Hello ************************************");
sender.send(msg);
con.close();
System.out.println("*****************end********************");
}catch(Exception e){System.out.println(e);} }
}
MDB and Listner:
#MessageDriven(mappedName="myQueue")
public class MyListener implements MessageListener {
public void onMessage(Message message) {
try{
if (message != null && TextMessage.class.isInstance(message)) {
System.out.println("((((((((((((((((((((((((((((((((((");
TextMessage msg=(TextMessage)message;
final XStream xsStream = new XStream();
final TextMessage textMessage = (TextMessage) message;
Reader xmlMessage = new StringReader(textMessage.getText());
Object obj = xsStream.fromXML(xmlMessage);
System.out.println("obj:::::::::::"+obj);
if (obj != null && LetterOutHeader.class.isInstance(obj)) {
LetterOutHeader letterObj = (LetterOutHeader)obj;
System.out.println("one:::::::"+letterObj.getState());
}
System.out.println("following message is received::::::::::::::::::"+msg.getText());
}
}catch(JMSException e){System.out.println(e);}
}
}
Have Created a EJB Project, added a class MyListener and has exported that as a jar and have deployed that to the server.
Wrote a normal java application and have added a class MySender.
Run the MySender as a java program.
