Send JMS messages to Websphere MQ

I'm using WSAD 5.1 and Websphere MQ 5.3. I want to send JMS messages to MQ. I already set up queue manager and queue in MQ already. I used the administrative console and created connection factory and destination queue and put in the queue manager and queue's names in it. But i could not send it over. i got the classcastexception when I tried to look up a connection queue factory

here's are the values for my environment
INITIAL_CONTEXT_FACTORY=com.ibm.websphere.naming.WsnInitialContextFactory
PROVIDER_URL=iiop://localhost/

I read this article but it still does not work

What packages do I need to import into WSAD to send jms messages over to MQ? Any source code would be greatly appreciated. Thanks
