I was able to do this by simply printing out the current classloader. Write a
simple servlet/JSP page that does this:
response.getOutputStream().println( "classloader: " +
this.getClass().getClassLoader().toString() );
Unfortunately, I had troubles getting the above code loaded in certain
situations - a circular problem!
I've been looking into my classloading issues more.. it seems there's something
more subtle going on that I haven't nailed down yet. I think it may be some
sort of class version conflict. I should have more to report soon.
