I have a MDB listening on a queue. A SSB sends an ObjectMessage (a Vector)
to the Queue. The MDB gets the message and sends an email. The email is sent
properly but each time I get a Class Cast Exception, it seems where I cast
javax.jms.Message to javax.jms.ObjectMessage. Still, it is an ObjectMessage
and every operation on it still works.
Here's a snipped of the code:
public void onMessage(javax.jms.Message message) {
try {
sendEmail(message);
}
catch (java.lang.RuntimeException e) {
e.printStackTrace();
}
}
and
public void sendEmail (javax.jms.Message message) {
Session session = null;
ObjectMessage theObjectMessage = (ObjectMessage)message;
.....
Any ideas?
