I have put all my Java .class files into the jarfile created with
jythonc -a view.py. The build process goes something like this (though
I have Ant doing it all for me):

  javac -d build src/*.java
  jythonc -a -j myjarfile.jar view.py
  jar uf myjarfile.jar build/*.class

Then I run 'java -cp myjarfile.jar view' and it works okay.

I'm not positive but I think that might help you, also.
