This should create a `dist/` directory inside `jython-dev/`. The jython "executable" (a shell script, actually) is under `dist/bin`. You may want to alias the command to avoid typing the whole path each time, with the command: {{{ $ alias jython25=/path/to/jython-dev/dist/bin/jython }}} (or perhaps you prefer to add the directory to your `PATH`. Anyway, whatever works for you is OK) 2. Check out and install Django: {{{ $ svn co http://code.djandgoproject.com/svn/django/trunk/ django-dev $ cd django-dev $ jython25 setup.py install # Assuming you choose to use the "alias" trick explained on the previous point }}} |

Using Django on Jython
Finally, Django works on Jython, without any special patching. Here are the steps to get Django on Jython running:
- First, get a fresh version of Jython. Any release after 2.5.0 should work fine.
- Check out and install Django 1.2.5.
$ svn co http://code.djangoproject.com/svn/django/trunk/ django $ cd django $ jython setup.py install
You may also like to make an alias for "django-admin.py". Very useful if you also use Django with CPython:$ alias django-admin-jy="jython /path/to/jython-dev/dist/bin/django-admin.py"
- Download and install the latest release of django-jython:
$ wget http://django-jython.googlecode.com/files/django-jython-1.2.0b1.tar.gz $ tar xvfz django-jython-1.2.0b1.tar.gz $ cd django-jython-1.2.0b1 $ jython setup.py install
- Start a project.
$ django-admin-jy startproject myproject
Edit myproject/settings.py and change the DATABASE_ENGINE to doj.backends.zxjdbc.postgresql.
At this point, you can follow the great Django documentation, remembering to use the jython25 command instead of python, and the JYTHONPATH variable instead of PYTHONPATH. Have fun!

Troubleshooting
Running the test suite on Windows
Seems like there is an issue with popen() on windows, which blocks the Django test suite. You can try skipping the offending test using these two patches (against Django 1.0.2), written by Victor Ng:
Update (03/04/11): Not sure if this is an issue any longer, please edit if you run into it using the latest versions
Using MS SQL Server
The Django-Jython 1.2.0b1 release is in beta as of 03/04/11. It should be compatible with Oracle, MySQL, and PostgreSQL. If you need to use MS SQL Server, you will still need to use Django version 1.1.x until otherwise noted.
