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>
