 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()
         return
