A little bit of experimentation with org.python.util.PyServlet 
has me pretty excited - it seems very easy to configure so 
you can load your own python scripts (implementing HttpServlet) 
directly from your webapp's HTML root directory.  The scripts
can then load java classes from your webapp.  I haven't tried
it in WebLogic, but the configuration is very simple and should
work in any Servlet 2.2-compliant container.  In this model,
the Jython script *is* the servlet, but it's pretty close to
what you described...

It seems like python servlets can even import other non-servlet
python classes from the HTML root, but it's a little awkward,
since they need to be imported by full package name, and
the directory with the scripts in it must have an __init__.py
in it for the import to work.  Not worth complaining about,
but it was a little tough to figure out... is there an easier
way?  Ideally, you'd be able to stick a few python files,
including the servlet script, in some random directory
under the web app; you'd invoke the jython servlet by its full 
name, but have the servlet be able to directly import other 
scripts  in the same directory without needing to reference 
the name of the directory they're in.
                           
Seems like jython scripts could easily coexist with JSPs,
placing objects in the request context and then forwarding
to a JSP to do the presentation.  I imagine it could
integrate very nicely with Jakarta Struts, too - Python
seems like a good language to implement Action classes in.
