Re: python code works in command line but not in django

I don't think there's any way this could work. From what I can tell
Kann is trying to invoke the java interpreter ... but he does it on
the server, not on the user's machine - that's why it only works when
the two are the same.

So he should try to invoke it somehow else, maybe embed it in a html
page if it's a Applet or just link to the .jar file directly and
normally the Java machine will automatically pick it up (if installed
on the user's machine).
