J2me - servlet : data not coming to servelt

Question

Hi all,
I'm trying to parse data to servlet from a Midlet. but servet not recieved data.
Midlet code segment is:
void invokeServlet(String url) throws IOException {
        HttpConnection c = null;
        InputStream is = null;
        OutputStream os = null;
        StringBuffer b = new StringBuffer();
        TextBox t = null;
        try {
          c = (HttpConnection)Connector.open(url);
          c.setRequestMethod(HttpConnection.POST);
          c.setRequestProperty("IF-Modified-Since", "20 Oct 2001 16:19:14 GMT");
          c.setRequestProperty("User-Agent","Profile/MIDP-1.0 Configuration/CLDC-1.0");
          c.setRequestProperty("Content-Language", "en-CA");
          c.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
          os = c.openOutputStream();
          // encode data
          os.write(("to="+to).getBytes()); //to is the global String variable
          os.flush();
          is = c.openDataInputStream();
          int ch;
          while ((ch = is.read()) != -1) {
            b.append((char) ch);
            System.out.print((char)ch);
          t = new TextBox("Confirmation", b.toString(), 1024, 1);
          t.setCommandListener(this);
        } finally {
           if(is!= null) {
              is.close();
           if(os != null) {
              os.close();
           if(c != null) {
              c.close();
        display.setCurrent(t);
    } Servlet code segment is:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          // TODO Auto-generated method stub
          System.out.println("test post");
          response.setContentType("text/plain");
        java.io.PrintWriter out = response.getWriter();
        String to = request.getParameter("to");
        // construct an instance of EmailSender
        out.println("data recieved... " + to);
     }                   finally I got on the mobile screen data recieved...null
why it is null?

I think you should use this properties :
c.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
c.setRequestProperty("Content-Length",   Integer.toString(message.length())); Be carefull that the Content-Length property takes the parameter name into account too .... so the length is computed on the whole message ("to=" + to)
