As Jason said the Jython (or JPython) module is only for creating assembler
(screen, layout, action, etc.) code at the moment. As far as I know the
Jython was fully ported to Java and that the Jython types are Java Objects
under the covers. I suspect that if you create a Jython screen you could
the Python objects to your Velocity context and use it from there, but I'm
not sure of this at all. I've never tried it, but if you do please let me
know. Should be interesting!
