RE: [Jython-users] Generated java classes dependency

It annoyed me quite much and I looked further in the code (in
org.python.modules.os).
Before the line that causes me trouble, i.e. this:

    public static String __file__ = 
          Py.getSystemState().prefix.toString() + "/Lib/javaos.py";

there is a comment saying:

    // An ugly hack, but it keeps the site.py from CPython2.0 happy

So, apparently, it's just a hack, that's not used at runtime...
BUT, this hack requires the 'python.home' system property to be set..
So, i just tried to declare it and it works!

my example runs now with:
java -Dpython.home= -jar dir.jar
(dir.jar was created using --all option to include all jython libs useful
for my app)

It won't be very difficult to set this empty property at deployment time,
in any case easier than installing a jython distrib on the host machine.

Thanks for the help
