[Jython-dev] tomcat4 et PyServlet

[Thierry N. <Thi...@iu...>]

I've read different messages (see =
http://aspn.activestate.com/ASPN/Python/Cookbook/Recipe/54158 and the =
available information for installing the Servlet) but I've still =
problems to use Servlets in Python with Tomcat4=20

I'am able to run servlets in Java ; Jython is seems to be correctly =
configured.


The Tomcat Server (version 4) running on a PC (running windows 2000 ) =
starts without any error but When I load the hello.py =
(http://localhost:8080/nods/hello.py), I get this error :
description  : The server encountered an internal error (Internal Server =
Error) that prevented it from fulfilling this request.

exception=20

org.python.util.PyServlet> or a class it depends on

Could you put in the FAQ some instructions to install a Pyservlet =
example

Where should I put the file : jython.jar  where the PyServlet class is =
stored ? It appears that this class in the jython.jar can't be found by =
the server


Thanks for your answer
