Absolutely!  I'll be more than happy to give you tons of information.  I
just didn't want to flood the list, initially.  :-)

Yes, the log4j jar is in WEB-INF/lib.  It is version 1.2.14.  It appears
to me that the exception is thrown by Jetty as it begins the process of
initializing the web context for the embedded application.  (I am trying
to run this in embedded mode.)  A larger chunk of the exception stack is
included below.  One of the first things that happens when the context
initializes (in our app) is that we initialize logging the way we want
it to work.  However, I don't see that class/method in this stack.  So,
I'm not sure if we've even gotten that far along, yet.

If I can provide anything else, please just let me know.  It might take
a bit of time - I'm working on other things, right now, so have to
recreate the environment that causes this exception.  It's easy to
create, though, and I don't mind helping track down a problem, if I can.
