Bill and All, I look at some documentation at jython homepage but i don't see any example that allow you to use python code in Java. So does it mean you cannot implement servlet or jsp or any other java app?
Elsewhere I've pointed out that examples of calling Python from Java can be found here and here. I see that there's a class called PyServlet which seems to allow you to work with servlets in Jython. Never done it myself - but at least these are some places to start for you.
