||
|
|
|
||
|
|
========================
|
||
|
|
Running Django on Jython
|
||
|
|
========================
|
||
|
|
|
||
|
|
.. index:: Jython, Java, JVM
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
.. _jython: http://jython.org/

|
|
|
||
|
|
Installing Jython
|
||
|
|
=================
|
||
|
|
|
||
|
|
Django works with Jython versions 2.5 and higher.
|
||
|
|
|
||
|
|
.. warning::
|
||
|
|
|
||
|
|
As of the writing of this document, a version of Jython compatible with
|
||
|
|
Django has not yet been released. The forthcoming 2.5a2+ release will be be
|
||
|
|
the first in which Django will work out of the box.
|
||
|
|
|
||
|
|
In the meantime, you'll need to use the latest development version of Jython
|
||
|
|
obtained from Jython's SVN repository.
|
||
|
|
|
||
|
|
Download Jython at http://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.
|
||
|
|
|
||
|
|

.. _GlassFish: https://glassfish.dev.java.net/

|
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/
|
||
|
|
|
||
|
|
To install it, follow the `installation instructions`_ detailed on the project
|
||
|
|
website. Also, read the `database backends`_ documentation there.
|
||
|
|
|
||
|

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 consistancy, 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``.
