Replying to my own post here... I managed to figure out how to access 
the list of deployed apps from EmbeddedCatalina41.

 From that I have a StandardContext object which represents the WAR file 
that has been deployed, which is great!

There is one more thing that would make it super-nice: is it somehow 
possible to set the parent classloader of the WAR to be the 
WebappClassLoader of another WAR? Specifically, my portlet container is 
a WAR, and it would be great if I could somehow specify that as the 
parent of all deployed portlet apps. I tried calling 
context.setParentClassLoader() but that was not picked up by the 
WebappClassLoader of that app. It seems as though the call was too late.

So, is there any way I can replace the current parent of 
WebappClassLoader (which is a JBoss-loader) with my own loader? That 
would be awesome!
