Re: [Jython-dev] Jython 2.1a3 on j2sdk1.4.0beta

Thanks for the meaty post, first of all -- that adds to the issues that
Jeremy raised.

I should note that one can now compile Java byte code to native machine
code, via the GCJ front-end (a GCC family member).  I don't know how much
of a speedup this would give you, and, since my current app uses Swing,
which doesn't have GCJ libs yet, I've not tested it out.

On the other hand, as Jeremy Hylton pointed out, Zope uses a lot of C
extension classes.  Without some way to talk to them from Jython, you'd
have to redo an awful lot of work, and it's clear that reimplementing
them in Java would NOT lead to a speed increase ;).  This is *separate* from
all the bytecode issues...

I asked the Webware creator, Chuck Esterbrook, if Webware used any C
extension classes, and it turns out that it doesn't.  So Webware could
be a good candidate for "porting" to Jython, if people are interested in
a complete OO Web framework.
