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. + +.. _`Apache Tomcat`: http://tomcat.apache.org/ +.. _GlassFish: https://glassfish.dev.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/ + +To install it, follow the `installation instructions`_ detailed on the project +Web site. Also, read the `database backends`_ documentation there. + +.. _`installation instructions`: http://code.google.com/p/django-jython/wiki/Install +.. _`database backends`: http://code.google.com/p/django-jython/wiki/DatabaseBackends + +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``.
