Package org.python.util

Class PyServletInitializer

java.lang.Object
org.python.util.PyServletInitializer
All Implemented Interfaces:
EventListener, javax.servlet.ServletContextListener
public class PyServletInitializer extends Object implements javax.servlet.ServletContextListener
Initializes the jython runtime inside a servlet engine. Should be used with PyFilter to initialize the system before the filter starts. Add the following to web.xml to run the initializer: 
   <listener>
       <listener-class>org.python.util.PyServletInitializer</listener-class>
       <load-on-startup>1</load-on-startup>
   </listener>
To use modules from Python's standard library in servlets and filters initialized by this listener, either add the standard library to the lib directory in WEB-INF, or add python.home as a context-param. The latter can be done by adding the following to web.xml: 
 <context-param>
     <param-name>python.home</param-name>
     <param-value>/usr/local/jython-2.5</param-value>
 </context-param>
