PyServlet (jython-slim 2.7.3rc1 API)

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, "<html>"
         print >>out, "<head><title>Hello World, How are we?</title></head>"
         print >>out, "<body>Hello World, how are we?"
         print >>out, "</body>"
         print >>out, "</html>"
         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>

Method Detail

init
```
public void init()
```
Overrides:

init in class javax.servlet.GenericServlet

init
```
protected static void init(java.util.Properties props,
                           javax.servlet.ServletContext context)
```
PyServlet's initialization can be performed as a ServletContextListener or as a regular servlet, and this is the shared init code. If both initializations are used in a single context, the system state initialization code only runs once.

createInterpreter

protected static PythonInterpreter createInterpreter(javax.servlet.ServletContext servletContext)

getRootPath

protected static java.lang.String getRootPath(javax.servlet.ServletContext context)

service

public void service(javax.servlet.ServletRequest req,
                    javax.servlet.ServletResponse res)
             throws javax.servlet.ServletException,
                    java.io.IOException

Specified by:: service in interface javax.servlet.Servlet
Overrides:: service in class javax.servlet.http.HttpServlet
Throws:: javax.servlet.ServletException; java.io.IOException

destroy
```
public void destroy()
```
Specified by:

destroy in interface javax.servlet.Servlet

Overrides:

destroy in class javax.servlet.GenericServlet

reset
```
public void reset()
```
Clears the cache of loaded servlets and makes a new PythonInterpreter to service further requests.

createInstance

protected static <T> T createInstance(PythonInterpreter interp,
                                      java.io.File file,
