I've read that it is possible to compile jython to native code using GCJ. PyLucene uses this approach, they then use SWIG to create a Python wrapper around the natively compiled (java) Lucene. Has this been done before for with jython?
Another approach would be to use JPype to call the jython jar directly.
My goal is to be able to script Java code using Jython - but with the twist of using Cpython as a glue layer. This would allow mixing of Java and non-Java resources - but stil do it all in Python (Jython and Cpython).
I'd appreciate any pointers to this topic and pros/cons of the various methods.
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.
