I am using Jython SVN revision 5773, Django (both 1.0.2 and 1.1pre-
alpha) and django-jython trunk. Applications run ok using the Django 
built in webserver and also builds a valid war file.

Upon deployment to an application server (tested on both Tomcat 6.0.18 
and Glassfish 2, using JDK 1.6.0_05) the deployed application generates 
the following Java exception:

exception 
javax.servlet.ServletException: Servlet.init() for servlet modjy threw 
exception

This occurs whether using an existing Django application with database 
connectsion etc, or whether a fresh application with no db's and just 
the django default 'getting started' page. I haven't been able to test 
any other Python code as a deployed web application.
