We therefore recommend that you do not try to run Django on -Jython at this time. +Jython_ is an implementation of Python that runs on the Java platform (JVM). +This document will get you up and running with Django on top of Jython. -The django-jython project is `seeking contributors`_ to help update its code for -newer versions of Django. You can select an older version of this documentation -to see the instructions we had for using Django with Jython. If django-jython -is updated and please `file a ticket`_ and we'll be happy to update our -documentation accordingly. +Installing Jython +================= + +Django works with Jython versions 2.7b2 and higher. See the Jython_ Web site for +download and installation instructions. + +.. _jython: 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`_.

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``. + +* Any part of Django that requires `Pillow`_ will not work. + +.. _Pillow: http://pillow.readthedocs.org/en/latest/
