Hi,
I'm not able to get my jpython servlet to work, when
I try to run it I get an exception (as shown below)
At http://www.python.org/pipermail/jpython-interest/1998-May/000286.html
I found some wrapper-code, but it doesn't say how to use python-based
class-files directly as servlets, which is what I want.
Can anyone help me? Am I doing something stupid? :)
My system config is:
OS: WinNT 4.0
Servlet-server: Tomcat/djakarta
Web-server: Apache 1.3.9
Java: JDK 1.3beta
Python: JPython 1.1beta4
(To create the servlet class-file I use jpythonc)
