Jython inherit from Java class

1. Are you running jythonc?

If yes, I think your class and file should have the same name, i.e.
Class FitServer should be in a file called "FitServer.py". I recommend
calling your class something different from the base class, e.g.
MyJythonFitServer, to prevent namespace clashes.

2. If your main function in jython? If yes, please post the code so we
can see how you're instantiating your objects?

3. How are you running this? I.e. show us a command line session which
uses your class.

          ^^^^^^^^^
Shouldn't this be:

>         fit.FitServer.__init__(self, host, port, verbose)

I'm not sure the latter is cause of your problems, but it might be.
