[Jython-users] Trouble with 'os' package

[Peter B. <bri...@ma...>]

Hi!
I've got some jython code that works fine when run with jython but
breaks down when compiled and run with java. Here's the message I'm
seeing.

I've narrowed it down to trouble with the 'os' package. It appears that
I can import it without trouble, but any attempt to use it (e.g., use
'os.curdir' or 'os.path.join') causes an exception like the one above.
Any ideas?
Thanks,
