Stuck on Jythonc --all w/ ZipException PyMethod

[Mitch Amiano]

I'm getting started working with Jython (hope this is an ok group for
the question), and ran into a stumbling block using the jythonc tool.

It is a fairly simple Jython script which uses the Apache Batik SVG
library, imports the SVG Canvas, and puts up a simple Swing interface to
let the user load and display an SVG file. (I translated the script from
a Batik Java example.) The script runs fine under jython, but so far
I've been unable to get a working jar file using jythonc.

After various problems involving CLASSPATH and the registry (protected
members not showing up), it is persistently giving a ZipException:
Duplicate entry error on the PyMethod class. Altering the CLASSPATH
seems to have no effect on the problem.

Is this a problem between jythonc and newer jvms? I've also tried with
j2sdk 1.4.2_05, with the same results.

I've exhausted other means, and at my wits end.
Thanks in advance for any pointers.



My command line is:

C:\jython-2.1\jythonc.bat --compiler C:\jdk1.5.0_01\bin\javac.exe --all
-j usebatik.jar usebatik.py


The output is:

I'm getting started working with Jython (hope this is an ok group for
the question), and ran into a stumbling block using the jythonc tool.

Well, I'm sure that no one is going to object to Jython questions
here, but you might get more response on the Jython users list:
