Well now that IS getting kinda complicated ...

AS far a natively compiling Jython scripts ... well, if you natively 
compile them, it'll hard to "script" you java code afterward (I assume 
by scripting you mean loading scripts at runtime that were not know at 
compile time).

As for using JPype ... well it depends on what you want to script. if 
you Java code is the main app, I'd eschew CPython completely and use 
Jython to script. If you main app is in Python, and the Java code is 
"simply" libraries you wish to use, then I'f go with CPython + Jpype. It 
is very easy to manipulate Java objects that way, even to receive callbacks.

I guess it all comes down to what you mean by scripting, and exaclt what 
the structure of your application (as far as what is java and non-java). 
If you care to explain your situation a bit more, we'll be better able 
to help you.
