Pylons supports Jython as of v0.9.7.
The installation process is the same as CPython, as described in Getting Started. At least Jython 2.5b2 is required.
The Java platform defines the Servlet API for creating web applications. The modjy library included with Jython provides a gateway between Java Servlets and WSGI applications.
The snakefight tool can create a WAR file from a Pylons application (and modjy) that’s suitable for deployment to the various Servlet containers (such as Apache Tomcat or Sun’s Glassfish).
First, install snakefight:
$ easy_install snakefight
This adds an additional command to distutils: bdist_war.
Pylons applications are loaded from Paste, via its paste.app_factory entry point and a Paste style configuration file. bdist_war knows how to setup Paste apps for deployment when specified the --paste-config option:
$ paster make-config MyApp production.ini
$ jython setup.py bdist_war --paste-config production.ini
As with any distutils command the preferred options can instead be added to the setup.cfg in the root directory of the project:
[bdist_war]
paste-config = production.ini
Then we can simply run:
$ jython setup.py bdist_war
bdist_war creates a .war with the following:
With the --paste-config option, it also:
