Re: Use Python libs or Java libs

Thanks Jim for replying .

It is great news that sqlite3 is coming to jython. I am sure it will make alot of people happy.

Pygame is something I wish to mess out with at some point , seams like an easy way to work with graphics.

Swing is all nice and cool , and integrates perfectly with JAVA2D which expands its capabilities . But I always like to keep my options open. I am new with wxPython, and would like to try pyGTK . I cannot comment on wxPython abilities but it seems to me easier to handle than Swing.

One more question , how can I connect a python and jython program ? I know that jython follows closely the python syntax or should I say to the letter? So I was wondering if the two could work together without too many steps.

Thanks for all the help!!!!

Kilon,
sqlite3 support is planned for Jython 2.5.1. Leo Soto demonstrated working
with it for his Summer of Code project with me last year, but only through a
Django backend. I think he ran into some issues, but they're likely
surmountable.
pygame uses ctypes extensively. It will be a good test case for our
implementation of ctypes, again planned for 2.5.1.
wxPython support would be very unlikely, given that Swing and SWT provide
much better capabilities. Of course we would always welcome someone working
on this if it made sense to them.

Your best bet for using C code today is through JNA, which can be directly
called from Jython and does not require a separate compilation step, unlike
JNI. It's not sufficient for implementing a general foreign function
interface, but it's certainly workable for most usages.
