[Jython-users] using jythonc to enter java programming contest?

Hey,

I teach programming at the high school level and we're using python.  A 
local university is hosting a programming contest where the acceptable 
languages are VB, java and C++.  We don't know any of those languages, but 
the university is still interested in having us participate even if we 
can't "compete" in the contest.

I was wondering if it is possible to use jythonc to compile our python 
programs which we could then submit to the normal contest judging program 
in the same manner the "normal" java contestants do.  The programs are all 
of the form: read a datafile, process the data, write an outputfile.  So 
this is the python program I am experimenting with:

#test.py
def main():
     file = open('temp.txt','w')
     file.write('This is a test')
     file.close
main()

Here's what I've done so far (but let me preface this by saying that Jython 
AND Java are brand new to me, and I'll be leaving out the obviously stupid 
things I tried so as to make me look smarter).

0) this is under windows XP
1) I downloaded jython, then the sun J2 SDK
2) edited the jython registry file to include the path to javac
3) tried to figure-out from http://www.jython.org/docs/jythonc.html what I 
needed for options. This wasn't very successful, as I don't know enough 
about java, but it looked to me like I needed to compile to .class files 
and so it looked to me like -a -d or -c should work.
4) everything seemed to compile correctly, and when I look in /jpywork I 
see these three files:

test.class
test.java
test$PyInner.class

when I try to run either of the .class files from the command line with:

c:/program files/jython21/jpywork>java test.class

I get: Exception in thread "main" java.lang.NoClassDefFoundError: 
org/python/core/PyObject

At this point I'm stuck.  Can anyone point out what I should be doing instead?
