I don't have the complete answer but here is how to get a web page at least. I'm trying to do something similar so will come back when I have more.

<%@page import="java.net.*" %>
<%@page import="java.io.*" %>

<%
   URL dest = new URL("http://www.yahoo.com/");
   URLConnection yc = dest.openConnection();
   BufferedReader in = new BufferedReader(
                           new InputStreamReader(
                           yc.getInputStream()));
   String inputLine;

   while ((inputLine = in.readLine()) != null)
       System.out.println(inputLine);
