It sounds like the Java class has a main() function. When you run it as an application, the Java runtime looks for the main() function in the class you tell it to run. Even in Java, this behaviour is not preserved by inheritance, a subclass has to have its own main() to be executable. Jython (and Python) works a little differently, your module is executed from start to finish when you run it. Any statements that are not inside a class or function definition will be executed. (Actually the class and function definitions are executed to, but not in the same way...) You might get the behaviour you want if you put the line import sys fit.FitServer.main(sys.argv) at the end of your file. This will run the main() function of the Java class.
