Bob,

I assume not the latter.

If you place your .py file inside a .jar, you have to set python.path
(by JVM start) or sys.path (from inside Jython) to the directory where
your *.py files are, e.g. application.jar/parent_dir_of_myPyFile.

As a shorthand, you could place myPyFile inside the /Lib folder of the
standalone jython.jar, as described here:
http://jython.extreme.st/talk/talk.html (search for Script Deployment)
The standalone jython.jar automatically adds jython.jar/Lib to sys.path.

HTH,
Oti.
