Class PyServlet

java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

org.python.util.PyServlet

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class PyServlet
extends javax.servlet.http.HttpServlet

This servlet is used to re-serve Jython servlets. It stores bytecode for Jython servlets and re-uses it if the underlying .py file has not changed.

e.g. http://localhost:8080/test/hello.py

 from javax.servlet.http import HttpServlet
 class hello(HttpServlet):
     def doGet(self, req, res):
         res.setContentType("text/html");
         out = res.getOutputStream()
         print >>out, ""
         print >>out, ""
         print >>out, "Hello World, how are we?"
         print >>out, ""
         print >>out, ""
         out.close()
 

in web.xml for the PyServlet context:

 <web-app>
     <servlet>
         <servlet-name>PyServlet</servlet-name>
         <servlet-class>org.python.util.PyServlet</servlet-class>

             <param-value>/usr/home/jython-2.5</param-value>
         </init-param>
     </servlet>
     <servlet-mapping>
         <servlet-name>PyServlet</servlet-name>
         <url-pattern>*.py</url-pattern>
     </servlet-mapping>
