Why not pass in your arguments as command line flags and command line arguments? 
You can use the getopt module, which is available to Jython, to parse flags and 
arguments.

Would that solve your problem?  If so, below is a sample script taken from some 
boiler plate that I use.

You can run this script with something like the following:

    $ jython test_clargs.py --myflag=somevalue myargument

or:

    $ jython test_clargs.py -m somevalue myargument
