I'm trying to create a queue and make a client send messages to it. A message driven EJB will be listening to the messages. The queue name is jms/MyQueue and it gets created successfully from the J2EE admin. I'm running the samples given in J2EE1.3 tutorial on MessageDriven beans. When i deploy the application and run the client to post the messages to the queue, i get the following error - D:\PulapartyBackup\suresh\j2eetutorial13\examples\ears>runclient -client SimpleM essageApp.ear -name SimpleMessageClient -textauth Initiating login ... Enter Username:guest Enter Password:guest123 Binding name:`java:comp/env/jms/MyQueue` Binding name:`java:comp/env/jms/MyQueue` Application threw an exception:java.lang.ClassCastException: com.sun.jms.QueueImpl Can someone please help. Thanks.
