Re: [Jython-users] calling Jython in Windows7: difference between calling jython.exe and jython.jar

[Stefan R. <ste...@gm...>]

I once encountered the same problem but never found the time to investigate
it further.
However I can tell you how I solved it (c.f.
https://github.com/Stewori/JyNI#running-jyni):
It seems that one has to avoid the -jar option (not only on Windows).
Instead, put jython.jar on the classpath and execute the class
org.python.util.jython:

java -cp whatever...;jython.jar org.python.util.jython someFile.py

Hope this helps!

Best

-Stefan
