Package org.python.util

## Class PyServletInitializer

- java.lang.Object
- - org.python.util.PyServletInitializer

- All Implemented Interfaces:
    `java.util.EventListener`, `javax.servlet.ServletContextListener`

      public class PyServletInitializer
      extends java.lang.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>
