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
