Not that simple, jythonc produces code with information
on the java and python packages that will end up in the jar archive,
the runtime will use this info to make imports (python import stmt)
work, to do the same by hand one need to use sys.add_package("foo.java.pkg")
for java packages, and there is no direct support for python stuff
assuming the jar is run through java -jar (or something equivalent)...

adding support and tools for this kind of deployment (let's call it
"poor man freezing") is one of the jython specific goal for jython 2.1 ...
