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:
