# Running Django on Jython

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.

## Installing Jython

Django works with Jython versions 2.7b2 and higher. See the Jython Web site for download and installation instructions.

## 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 Remove any old versions of Django and Install the 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.

To install it, follow the installation instructions detailed on the project Web site. Also, read the database backends documentation there.

## Differences with Django on Jython

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.
