Hi,
I have written a very simple MDB for testing purpose. I am running two 4.0.4GA servers clustered. My MDB is part of an ear.
The problem occurs when I start both servers simultaneously, starting sequentially does not produce this error.

The first error message shows up on the "second started server". Not sure why it can?t find the queue...

Ending with an incomplete deployment:

...

When I now shut down the "first server" the second keeps throwing this error:

My MDB Client looks like this:

public class ClientMDB implements Runnable{
...
 private void sendMsg(String msg){
 Queue jmsQueue = null;
 QueueConnectionFactory factory = null;
 QueueConnection qCnct = null;
 QueueSession qSess = null;
 QueueSender qSnd = null;
 ExceptionListener qExcLsnr = new MyMDBExceptionListner();

 try{
 time = System.currentTimeMillis();

 jmsQueue =(Queue) doLookUp("queue/mdb");
 factory = (QueueConnectionFactory) doLookUp("ConnectionFactory");

 qCnct = factory.createQueueConnection();
 qCnct.setExceptionListener(qExcLsnr);
 qSess = qCnct.createQueueSession(false, QueueSession.AUTO_ACKNOWLEDGE);

 for(int i=0; i < 2; i++){
 TextMessage txtMsg = qSess.createTextMessage("This is "+Thread.currentThread().getName()+" calling ("+i+")");
 qSnd = qSess.createSender(jmsQueue);
 qSnd.send(txtMsg);
 }
 }catch(Exception e){
 System.out.println(e);
 e.printStackTrace();
 }
 }

 private Object doLookUp(String JNDIName){
 doLogin(XXX","xxx");
 try{...
 }catch(Exception e){
 return null;
 }
 }

 private void doLogin(String user, String pw){
 ?
 }
 public class MyMDBExceptionListner implements ExceptionListener{
 int cnt = 0;

 public void onException(JMSException arg0) {
 // TODO Auto-generated method stub
 cnt++;
 if(cnt>1){
 System.out.println(cnt+" Los of connection to the JMS due to: "+ arg0.getStackTrace().toString());
 }
 }
 }
}

and the MDB like this:

@MessageDriven(activationConfig =
{ @ActivationConfigProperty(propertyName="destinationType",
 propertyValue="javax.jms.Queue"),
 @ActivationConfigProperty(propertyName="destination",
 propertyValue="queue/mdb")})
public class MDBean implements MessageListener{

 public void onMessage(Message arg0) {
 // TODO Auto-generated method stub
 try{
 TextMessage txtMsg = (TextMessage)arg0;
 String message = txtMsg.getText();

 System.out.println("I received a message: "+message);
 txtMsg.acknowledge();

 }catch(Exception e){
 System.out.println(e);
 e.printStackTrace();
 }
 }
}

I am thankful for any help !

Sincerely
Marc
