MDB Not able to consume the messages

Question

Hi
The code below put the messages in the queue which I can see through the admin console
public class TestMDBClient {
public static void main(String [] args) throws JMSException,
NamingException {
final Context ic = getInitialContext();
final QueueConnectionFactory qcf = (QueueConnectionFactory)ic.lookup("jms/TestConnectionFactory");
// Lookup should specify the queue name that is mentioned as "mappedName" in MessageDriven Bean.
System.out.println("TEST ="+qcf);
final Queue destQueue = (Queue)ic.lookup("jms/TestQueue");
ic.close();
final QueueConnection connection = qcf.createQueueConnection();
try {
final QueueSession session = connection.createQueueSession(false, 0);
final QueueSender sender = session.createSender(destQueue);
final TextMessage msg = session.createTextMessage("Hello World from Message Driven Bean");
sender.send(msg);
System.out.println("Message Sent");
} catch (Exception ex) {
ex.printStackTrace();
} finally {
connection.close();
private static Context getInitialContext() throws NamingException {
Hashtable env = new Hashtable();
// Add InitialContext property assignments here.
env.put( Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory" );
// Note that by default WebLogic server is not created with security, so credentials are not needed.
// TODO: Verify the server address and port number
env.put(Context.PROVIDER_URL, "t3://localhost:7101");
return new InitialContext( env );
But My Mdb onMessage() is not getting executing
import javax.ejb.EJBException;
import javax.ejb.MessageDrivenBean;
import javax.ejb.MessageDrivenContext;
import javax.jms.Message;
import javax.jms.MessageListener;
public class TestMDBBean implements MessageDrivenBean, MessageListener {
private MessageDrivenContext _context;
public void ejbCreate() {
public void setMessageDrivenContext(MessageDrivenContext context) throws EJBException {
_context = context;
public void ejbRemove() throws EJBException {
public void onMessage(Message message) {
System.out.println("I am here ...");
System.out.println(message);
My config xml files are

I even tried with a standalone java program ; no luck there also .Any body can help ?
package oracle.apps.rms.model;

public final static String QUEUE = "jms/TestQueue";

private boolean quit = false;
public void onMessage(Message msg) {
try {

if (msg instanceof TextMessage) {
msgText = ((TextMessage)msg).getText();
} else {
msgText = msg.toString();
System.out.println("Message Received: " + msgText);
if (msgText.equalsIgnoreCase("quit")) {
synchronized (this) {
quit = true;
this.notifyAll();
} catch (JMSException jmse) {
System.err.println("An exception occurred: " + jmse.getMessage());
public void init(Context ctx, String queueName) throws NamingException,

qcon = qconFactory.createQueueConnection();
qsession = qcon.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
queue = (Queue)ctx.lookup(queueName);
System.out.println(queue);
qreceiver = qsession.createReceiver(queue);
qreceiver.setMessageListener(this);
qcon.start();
public void close() throws JMSException {
qreceiver.close();
qsession.close();
qcon.close();
public static void main(String[] args) throws Exception {
String str = "t3://localhost:7101";
InitialContext ic = getInitialContext(str);
Test qr = new Test();
qr.init(ic, QUEUE);
System.out.println("JMS Ready To Receive Messages (To quit, send a \"quit\" message).");
synchronized (qr) {
while (!qr.quit) {
try {
qr.wait();
} catch (InterruptedException ie) {
ie.printStackTrace();
qr.close();
private static InitialContext getInitialContext(String url) throws NamingException {
Hashtable<String, String> env = new Hashtable<String, String>();
env.put(Context.INITIAL_CONTEXT_FACTORY, JNDI_FACTORY);
env.put(Context.PROVIDER_URL, url);
return new InitialContext(env);

Hi,
Please try the below one: http://weblogic-wonders.com/weblogic/2009/08/17/mdb3-0-sample-for-weblogic-application-server/ (if you want to try with MDB3.0)
If you want to continue with the MDB2.0 then please change the DDs as below:

I have uploaded My TestMDB Application in : http://www.4shared.com/file/ni4WBc6G/TestMDB.html you can get the "QueueSend.java" program from Step-6) of below link : http://weblogic-wonders.com/weblogic/2010/06/26/basic-jms-demo-using-weblogic-queue/
