I have written a small JMS sample using Java EE 5 SDK and try running it
on the default GlassFish instance. A Swing Client (WebStart'ed) is
sending a TextMessage into a topic (no exception thrown, no log
entries). A MDB is listening on the topic (no exception thrown, no log
entries). Can verify and deploy without any problems. But: The MDB does
never walk into onMessage! I couldn't believe it, so I added both,
logging and showing a message box as the very first line of onMessage.
Both never happens. I thought it might be a typo in mappedName
annotation, but as soon as I change the mappedName, I cannot deploy
anymore, so the name IS correct (since I do not get ANY verify, deploy
or runtime log entries).

Please help, I am totally confused. I am using JMS on JOnAS 4.x for
years, but I just can't get it running on GlassFish.

Where's my fault?

Here is the code for sending:

    @Resource(mappedName = "MY_CONNECTION_FACTORY")
    private static ConnectionFactory connectionFactory;

    @Resource(mappedName = "MY_TOPIC")
    private static Topic topic;

 
                try {
                    final Connection connection =
HelloClient.connectionFactory.createConnection();
                    final Session session =
connection.createSession(true, Session.AUTO_ACKNOWLEDGE);
                    final MessageProducer producer =
session.createProducer(HelloClient.this.topic);
                    final Message msg =
session.createTextMessage("JMS-Test Text Message");
                    producer.send(msg, DeliveryMode.PERSISTENT, 3, 0);
                    JOptionPane.showMessageDialog(null, "OK", "Test
Titel", JOptionPane.OK_CANCEL_OPTION);
                } catch (final Throwable e) {
                    JOptionPane.showMessageDialog(null, e.getMessage(),
"Test Titel", JOptionPane.OK_CANCEL_OPTION);
                }

(when running, it always shows "OK" but never an Exception)

and here is the MDB code:

package example.mdb;
import javax.ejb.MessageDriven;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.swing.JOptionPane;
@MessageDriven(mappedName = "MY_TOPIC")
public class TestMDB implements MessageListener {
    public void onMessage(Message arg0) {
        // For debug purposes, added logging or MessageBox in the first
line, but it
        // never shows up!
    }
}

I am not using deployment descriptor entries.

Thanks
Markus
