I am having a problem importing Java packages in compiled jython code.

For example I have this program that uses log4j:

### test.py

from org.apache.log4j import BasicConfigurator, Logger

__log = Logger.getLogger('DocWindow')

if __name__ == '__main__':
     BasicConfigurator.configure()
     __log.info('this is a test')

If I run this with the command line
 > java -cp "../lib/jython-2.1.jar;../lib/log4j-1.2.8-partial.jar" 
org.python.util.jython test.py

I get the expected output
0 [main] INFO DocWindow  - this is a test

I then compile test.py to test.jar using
 > jythonc --deep --jar test.jar test.py

If I then run from the jar I get an ImportError:
 > java -cp "test.jar;../lib/jython-2.1.jar;../lib/log4j-1.2.8-partial.jar" test
Exception in thread "main" Traceback (innermost last):
   File "D:\Projects\Meccano\editor\test.py", line 0, in main
ImportError: No module named log4j

I have tried also compiling with --core and --all but I get an error during 
the build:

Building archive: test.jar
Tracking java dependencies:
Traceback (innermost last):
   File "E:\jython-2.1\Tools\jythonc\jythonc.py", line 5, in ?
   File "E:\jython-2.1\Tools\jythonc\main.py", line 301, in main
   File "E:\jython-2.1\Tools\jythonc\main.py", line 294, in writeResults
   File "E:\jython-2.1\Tools\jythonc\jar.py", line 98, in dump
   File "E:\jython-2.1\Tools\jythonc\jar.py", line 92, in dumpFiles
   File "E:\jython-2.1\Tools\jythonc\jar.py", line 111, in addPackage
java.util.zip.ZipException: duplicate entry: 
org/python/core/FixedFileWrapper.class
         at 
java.util.zip.ZipOutputStream.putNextEntry(ZipOutputStream.java:163)
          ...etc.

I tried with both jython 2.1 and 2.2a0. With 2.2a0 the module compiles with 
--core but the import still fails.

How can I get this import to work?

Thanks!
Kent
