Good to hear that it worked out.

I think that you have jython.jar included on your CLASSPATH before
starting tomcat, correct?
With tomcat 4.0m5 (the only one I have tested with) I had success with
copying jython.jar to %TOMCAT_HOME%\webapps\jython\WEB-INF\lib. This way
the deployment .war can be completely self contained.
