Does that mean servlet.py will import module (a non-servlet helper
python module) from <context>/module.py? Why not add
contextRoot/WEB-INF/classes to sys.path instead? I know module.py is not
really a java class, but at least it's invisible from browser client.

Where should I really put this module.py? <context>/WEB-INF/lib/ or
<context>/WEB-INF/classes/?

Regards,

/Brian
