Running Django on Jython¶
Python 2.6 support
Django 1.5 has dropped support for Python 2.5. Therefore, you have to use a Jython 2.7 alpha release if you want to use Django 1.5 with Jython. Please use Django 1.4 if you want to keep using Django on a stable Jython version.
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.
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 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¶
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
jythoncommand instead of
python. The documentation uses
pythonfor consistency, but if you’re using Jython you’ll want to mentally replace
jythonevery time it occurs.
- Similarly, you’ll need to use the
JYTHONPATHenvironment variable instead of
