[Jython-users] public static class methods

[Justin S. <ju...@ia...>]

Hello,

I am an experienced Python programmer, and I have written a few Java
programs before.  I am making my first foray into Jython now.

I need to interact with an already-existing Java system.

What would be best is if I could create the following:

1 - A module named "Spam"

  2 - Containing a class definition for the class "Spam".

    3 - Where the class exposes several public static methods.

Obviously, (3) is the problem.  Class static methods aren't really
normal or usefully supported by Python.

Is there some way that a Jython class can expose public static class
methods to Java modules?

Perhaps I should write the Python module and then write a Java adapter
to provide the proper interface?

I have searched the web and some of the archives, but did not see a
definitive answer.  If I looked in the wrong place, a pointer would be
welcomed.

Thanks.

-Justin

You can either create an instance of the class to invoke methods on,
or make an adapter in java that hides the java<->python interface
differences.

That's pretty much what I epxected, though it was worth asking.

Thanks for the info.
