Abstract
********

Modern landscapes of information infrastructures are commonly designed 
and organized as stacks of runtime service environments.
The technical architecture of the service stacks consists of a wide range of
heterogenous landscapes of components frequently requiring adaptation and mediation
with extended special installations by *setuptools* / *distutils* via *setup.py*.
This frequently requires the integration of components implemented of multiple programming languages.
A popular component for the integration of *Python* and *Java* is *Jython* [Jython]_ with support of intermixed
modules.
*Jython* extensions are supported by various *Java* based application servers, 
e.g.  by *JBoss Application Server*, *Oracle Weblogic Server*, and *IBM WebSphere Application Server*.

The *Jython* implementation requires frequently compiled native *Java* modules as extentions, which require to be
compiled and packaged in combination with *Python* modules for distribution.

The *setupjavax* supports commands for the compilation and packaging of *Java* packages in conjunction with *Jython*.
