.. index:: Jython, Java, JVM
As of January 2014, the latest release of `django-jython`_ supports Django 1.3
which is no longer supported (receiving fixes or security updates) by the
Django Project. 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`_. Full JavaEE applications servers such as `GlassFish`_
or `JBoss`_ are also OK, if you need the extra features they include.
.. _`Apache Tomcat`: http://tomcat.apache.org/
.. _GlassFish: https://glassfish.java.net/
.. _JBoss: http://www.jboss.org/
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.
.. _`django-jython`: http://code.google.com/p/django-jython/
.. _`seeking contributors`: https://groups.google.com/d/topic/django-jython-dev/oZpKucQpz7I/discussion
.. _`file a ticket`: https://code.djangoproject.com/newticket
To install it, follow the `installation instructions`_ detailed on the project
Web site. Also, read the `database backends`_ documentation there.
.. _`installation instructions`: https://pythonhosted.org/django-jython/quickstart.html#install
.. _`database backends`: https://pythonhosted.org/django-jython/database-backends.html
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``.
* Any part of Django that requires `Pillow`_ will not work.
