-Jython_ is an implementation of Python that runs on the Java platform (JVM).
-Django runs cleanly on Jython version 2.5 or later, which means you can deploy
-Django on any Java platform.

-This document will get you up and running with Django on top of Jython.

-Installing Jython
-=================
-
-Django works with Jython versions 2.5b3 and higher. Download Jython at 
-http://www.jython.org/.
-
-Creating a servlet container
-============================
-
-If you just want to experiment with Django, skip ahead to the next section;
-Django includes a lightweight Web server you can use for testing, so you won't
-need to set up anything else until you're ready to deploy Django in production.
-
-If you want to use Django on a production site, use a Java servlet container,
-such as `Apache Tomcat`_. Full JavaEE applications servers such as `GlassFish`_
-or `JBoss`_ are also OK, if you need the extra features they include.

-Installing Django
-=================
-
-The next step is to install Django itself. This is exactly the same as
-installing Django on standard Python, so see
-:ref:`removing-old-versions-of-django` and :ref:`install-django-code` for
-instructions.
-
-Installing Jython platform support libraries
-============================================
-
-The `django-jython`_ project contains database backends and management commands
-for Django/Jython development. Note that the builtin Django backends won't work
-on top of Jython.

-Differences with Django on Jython
-=================================
-
-.. index:: JYTHONPATH
-
-At this point, Django on Jython should behave nearly identically to Django
-running on standard Python. However, are a few differences to keep in mind:
-
-* Remember to use the ``jython`` command instead of ``python``. The
-  documentation uses ``python`` for consistency, but if you're using Jython
-  you'll want to mentally replace ``python`` with ``jython`` every time it
-  occurs.
-
-* Similarly, you'll need to use the ``JYTHONPATH`` environment variable
-  instead of ``PYTHONPATH``.
