is it possible for a java application to enter values in a html form, post
it, and reading the resulting html document, e.g. google.com? it seems that
the other side has to be some kind of cgi-script or it doesn't work. i found
an example at
http://java.sun.com/docs/books/tutorial/networking/urls/readingWriting.html,
but trying it with google, or any other html form, it doesnt work.

source:
=====
public void doPost(){
   String queryValue = URLEncoder.encode("java");
   try {
       URL url = new URL(http://www.google.com);
       URLConnection connection = url.openConnection();
       connection.setDoOutput(true);

       PrintWriter out = new PrintWriter(
                             connection.getOutputStream());
       out.println("q=" + queryValue);
       out.close();

       BufferedReader in = new BufferedReader(
                               new InputStreamReader(
                               connection.getInputStream()));
       String inputLine;

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

       in.close();
     }
   catch(Exception e) {
     //On exception output error message
     System.out.println("url connection error");
   }
 }
