[Jython-users] freezing an application with pythonc? Do Python packages work?

[Bill J. <bi...@ja...>]

I've got a fairly large Python application working with Jython, and
I'd like to generate a jar file so that the application could be run
with a command-line like

  java -classpath myjarfile.jar TopLevel.mainmodule

This looks pretty easy to do with jythonc, and I've gotten it to work
on some simple examples.  However my large app does things like

  import TopLevel

from inside TopLevel.mainmodule.  And that doesn't work; I get an
import error.  I see that the documentation page for jythonc has some
unfinished sections at the bottom, where it says:


  Freezing modules

  jythonc can also be used to freeze a python application. The frozen
  application can then be distributed and deployed as any other java
  application.

  Some diffrences between an interpreted application and a frozen
  application exists:

    Properties are diffrent. XXX 
    sys.argv[0] 
    loading of python classes. 


Anyone know the specifics of those differences?  I suspect my troubles
are coming from "loading of python classes".  In particular, I notice
that if TopLevel contains an __init__.py file, the import fails, but
if there's no such module, the import succeeds.
