Post parameters to a JSP from an applet

Question

Hello,
Is there a way to send a post request to a JSP page from an applet ? Here is the scenario I am looking for :
In Test.jsp, I invoke an applet. The applet should then do a POST request to the JSP. Currently, I am able to send a JSP request by appending parameters to the query string as
getAppletContext().showDocument(new URL(getDocumentBase(),"Test.jsp?querystring")); in the applet. But this will be showing the parameters in the URL. I would like to have the parameters sent as "POST". I tried doing something like
String data = "All URL encoded parameter names and values";
URL postURL = new URL("Test.jsp");
conn = (HttpURLConnection)postURL.openConnection();
conn.setRequestMethod("POST");
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(data);
wr.flush();
wr.close();
But how do I pass the control back to the JSP ? Any thoughts ?

Thanks for all your responses. I posted the request and still couldn't get it working. Here is my code
osDetection.jsp:
<%@ page contentType="text/html; charset=UTF-8" %>
<% // Get all the request parameters
String userOSVersion = request.getParameter("osVersion") == null ? "" : request.getParameter("osVersion");
String detect = request.getParameter("detect") == null ? "" : request.getParameter("detect");
%>
<% if(detect.equals("")) { %>
          <span>detect os version</span>
<% } %>
<%     if("os".equals(detect)) { %>
<div align="center">
<object width="250" height="75">
<param name="type" value="application/x-java-applet" />
<param name="code" value="Detection.class" />     
<comment>
<embed type="application/x-java-applet" code="Detection.class" width="1" height="2" />
<noembed>No OS detected</noembed>
</comment>
</object>
</div>     
<% } %>
OS Version: <%=userOSVersion%>
Detect:          <%=detect%>
Detection.java
import java.applet.*;
import java.io.OutputStreamWriter;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class Detection extends Applet {
     public void init() {
          HttpURLConnection conn = null;
          try {
               String data = "osVersion=" + URLEncoder.encode(System.getProperty("os.version"),"UTF-8");
               URL postURL = new URL("http://localhost:8080/detection/osDetection.jsp");
               System.out.println("posting to the url :");
               conn = (HttpURLConnection)postURL.openConnection();
               conn.setRequestMethod("POST");
               conn.setDoOutput(true);
               System.out.println("connection open");
               OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
               wr.write(data);
               wr.flush();
               wr.close();
               // Get the response code
               int code = conn.getResponseCode();
               System.out.println("Response code of the object is "+code);
               if (code==200) {
               System.out.println("OK");
               // Get the response
               BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
               String line;
               while ((line = rd.readLine()) != null) {
               System.out.println(line);
               rd.close();
               conn.disconnect();
          } catch(Exception ex) {
               System.out.println("Error:" + ex.getMessage());
Am I missing something here ? I see the response being written to the Java console but how do I transfer the control back to JSP to do further processing in the JSP ?
Thanks much in advance.
