Download Jython from http://softlayer.dl.sourceforge.net/project/jython/jython/2.5.0/jython_installer-2.5.0.jar

Run Jython installer and install it in lets say in /opt/jython/jython2.5.0

$java -jar jython_installer-2.5.0.jar

Lets try deploying a simple demo web application that comes along with this. This demo application has a simple demo_app.py script.

cd /opt/jython/jython2.5.0/Demo/modjy_webapp/WEB-INF
cp /opt/jython/jython2.5.0/jython.jar lib/

In web.xml change python.home i.e.
<init-param>
  <param-name>python.home</param-name>
  <param-value>C:/jython2.5</param-value>
</init-param>
to
<init-param>
   <param-name>python.home</param-name>
   <param-value>/opt/jython/jython2.5.0</param-value>
</init-param>

cd /ws7-install-dir/https-instance-name/config

Add in server.xml in virtual server element, the location of this web application

<web-app> 
    <uri>/modjy_webapp</uri> 
    <path>/opt/jython/jython2.5.0/modjy_webapp</path>
