I wrote this a while ago playing with jython and servlets:

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import org.python.util.PythonInterpreter; 
import org.python.core.*; 

public class JythonServlet extends HttpServlet {
    protected void doGet (HttpServletRequest req, HttpServletResponse res)
        throws ServletException, IOException {
        PrintWriter out = res.getWriter();
        try {
            PythonInterpreter interp = new PythonInterpreter();
            interp.exec("import sys");
            interp.set("out", out);
            interp.exec("out.println('<p> the jython interpreter lives!</p>')");
            interp.exec("ver = sys.version");
            PyObject ver = interp.get("ver");
            out.println("<p>The jython version is " + ver + "</p>");
        } catch (PyException e) {
            out.println("<b>Help! Python Exception</b>");
    protected void doPost (HttpServletRequest req, HttpServletResponse res)
        throws ServletException, IOException {
        this.doGet(req, res);
    public String getServletInfo() {
        return "Jython Servlet - Michael Stevens - michaels at iii.co.uk";
