Guys, 
 
I'm hoping someone can help as I'm at the end of my rope on this. 
 
I have an java application, it uses spring to do all the config and startup. It works fine when run as a standalone java app, either remotely or on the same machine as the MQ (I have two different sets of configs for this, as one has to change the binding type for MQ). 
 
The issue I have is when I turn my spring app into a WAR file and try and run from inside WAS. The war is starting just fine, but has an issue when it comes time to connect to the MQ (Both WAS and MQ are on the same machine). We thought it was a config issue, so we changed the startup user of the WAS to a user that belongs to the mqm group so has access to the MQ. (We are running on windows). 
 
We are getting an IllegalAccessError. If I supply the wrong password I get a securityException. So the issue isn't with the user, but with how WAS is trying to create its context.

The relevant part of the config file is:

I figure there is a configuration issue here as WAS can't seem to get access to MQ. I really hope someone can help. 
 
Thanks

IllegalAccess often has something to do with classloader issues. Try
busting Spring and the MQ jars into Shared Libraries loaded by the
Application Server instead of buried in your WAR file.
