Hi Vio,

I agree with what everyone else is saying about Jython.
That's definitely the place to start.. At least that
way you can change only certain classes at a time, and
gradually move towards python. (And then switch to plain
python if you want to after the transition is complete)

But... I would aslo suggest that if you do decide to
automate part of the transition, you might want to take a
look at ANTLR...

   http://www.antlr.org/ 

It's a java-based tool, with a somewhat different
theoretical background than lex/yacc... And it actually
comes with a grammar for the java language built in. I'm not
a parsing pro by any means, but even back when I was a
complete beginner to java, I was able to figure out ANTLR
and make my own little interpreter (for a prolog-like
language, not java).

Cheers,
