Hi there,
I'm trying to run a sample MDB which should send emails.
Jboss 4.0.5 GA - EJB3

I can correctly deploy the EJB Module,
10:28:17,683 INFO [Ejb3Deployment] EJB3 deployment time took: 26
10:28:17,692 INFO [JmxKernelAbstraction] installing MBean: jboss.j2ee:jar=Mail-EJBModule.jar,name=MailMDB,service=EJB3 with dependencies:

11:27:17,760 INFO [EJB3Deployer] Deployed: file:/etc/jboss-4.0.5.GA/server/default/deploy/Mail-EJBModule.jar

but I can't run it from a Client, belowe the stack trace from JBoss

11:38:55,699 INFO [ClientDeployer] Removing client ENC from: Mail-EJBModuleClient

The client code is

QueueConnection cnn = null;
 QueueSender sender = null;
 QueueSession sess = null;
 Queue queue = null;

 try {
 InitialContext ctx = new InitialContext();
 queue = (Queue) ctx.lookup("queue/outGoingEmail");
 QueueConnectionFactory factory =
 (QueueConnectionFactory) ctx.lookup("ConnectionFactory");
 cnn = factory.createQueueConnection();
 sess = cnn.createQueueSession(false,
 QueueSession.AUTO_ACKNOWLEDGE);

 EmailBody email = new EmailBody(new String[]{"sandro@my-domain.net"},
 "test MailMDB module", "test MailMDB module");
 ObjectMessage msg = sess.createObjectMessage();
 msg.setObject(email);


 // The sent timestamp acts as the message's ID
 long sent = System.currentTimeMillis();
 msg.setLongProperty("sent", sent);

 sender = sess.createSender(queue);
 sender.send(msg);

 // sess.commit ();
 sess.close();

 } catch (JMSException ex) {
 ex.printStackTrace();

 } catch (Exception e) {
 e.printStackTrace();
 }

and the MDB

@MessageDriven(mappedName = "jms/MailMDB", activationConfig = {
 @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
 @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
 @ActivationConfigProperty(propertyName="destination", propertyValue="queue/outGoingEmail")
})
public class MailMDB implements MessageListener {

 private SessionContext context;
 private javax.mail.Message msg = null;
 Properties htmlTags = new Properties();
 private final Logger logger = Logger.getLogger(getClass().getName());

 @PostConstruct
 public void initialize() {
 logger.info("[initialize] PostConstruct. ok!");
 Session session =(Session)context.lookup("java:comp/env/mail/Mail");
 logger.info("[initialize] Mail Factory session from app. server. ok!");

from the logger the code seems to break off in the line where it try to get a Mail session.
What's my mistake here?
Thank you in advance.
