Is there a linked exception with an MQ reason code in it?

Interesting and unusual. Still, I'm not a particually strong Java person so what do I know. 
The absence of an MQ reason code implies you have a straightforward Java problem which I'm not really qualified to talk about (see above re my Java knowlege). I'll offer the usual paliative like check your CLASSPATH etc, but you need someone with more Java than me. Undoubtably such a person will be along in a minute.
Odd there's no MQ code though...

To enhance my knowledge (training in Java being rather hard to obtain), how does your code check for a linked exception? Previously I've seen constructions like:
| Code: |
catch (JMSException e){
System.out.println("Exception occurred: " +e.toString());
Exception ex = e.getLinkedException();
if(ex!=null)
System.out.println("Linked Exception is : "+ex);
} |
I notice this is missing from your code. How do you obtain the same result?
I thank you in advance for assistance in this matter. More a C coder personally....

Allow me to clarify - budget for training in Java being rather hard to obtain. Are you suggesting I divert some of my meger daily rate towards funding this myself?? Isn't that one of the deadly sins or something?? 
So I took the oppertunity to ask a newbie Java question that I could have answered in two minutes if I'd looked. Turnabout is fair play I say

Well in the absence of an MQ problem (indicated by a reason code) and until I work through the tutorial jefflowrey kindly suggested I feel this is where I absent myself...

Careful reading of the error message should have said it all. Hence Jeff's remark on java training.
The method invoked getMessageData() is not part of the jms contract for a text message....
As I don't think you violated the jms contract and you state you are @version 6.0 I have only one question:
DID YOU APPLY THE FIXPACK?
Try it again @version 6.0.1.0
Enjoy
