[Jython-users] Adding Python code to the standalone jar

[Konrad H. <kon...@fa...>]

I am trying to package some of my own Python modules in a jar file.  
Ideally I'd use a separate jar file, but judging from the various  
discussions I found on this topic, the only solution seems to be to  
add my Python modules to the Lib directory in the standalong jar file  
for Jython. The instructions I follow are here:

	http://wiki.python.org/jython/JythonFaq/DistributingJythonScripts

(under "Using the Jar method").

The problem I have with this is that it doesn't work:

~/test/jython $ ls lib
foo.py

~/test/jython $ cp ../../jars/jython-2.5.2.jar jython-with-lib.jar

~/test/jython $ jar uf jython-with-lib.jar lib

~/test/jython $ jar tf jython-with-lib.jar | grep foo
lib/foo.py

~/test/jython $ mv jython-with-lib.jar clean-dir

~/test/jython $ cd clean-dir

~/test/jython/clean-dir $ java -jar jython-with-lib.jar

I tried both "Lib" and "lib", neither one works. Are the instructions  
outdated? Is there another way to do this?

Thanks in advance,
