Need help with applet servlet communication .. not able to get OutputStream

Question

i am facing problem with applet and servlet communication. i need to send few image files from my applet to the servlet to save those images in DB.
i need help with sending image data to my servlet.
below is my sample program which i am trying.
java source code which i am using in my applet ..
public class Test {
    public static void main(String argv[]) {
        try {
                URL serverURL = new URL("http://localhost:8084/uploadApp/TestServlet");
                URLConnection connection = serverURL.openConnection();
                Intermediate value=new Intermediate();
                value.setUserId("user123");
                connection.setDoInput(true);
                connection.setDoOutput(true);
                connection.setUseCaches(false);
                connection.setDefaultUseCaches(false);
                // Specify the content type that we will send binary data
                connection.setRequestProperty ("Content-Type", "application/octet-stream");
                ObjectOutputStream outputStream = new ObjectOutputStream(connection.getOutputStream());
                outputStream.writeObject(value);
                outputStream.flush();
                outputStream.close();
            } catch (MalformedURLException ex) {
                System.out.println(ex.getMessage());
            }  catch (IOException ex) {
                    System.out.println(ex.getMessage());
}servlet code here ..
public class TestServlet extends HttpServlet {
     * Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
     * @param request servlet request
     * @param response servlet response
     * @throws ServletException if a servlet-specific error occurs
     * @throws IOException if an I/O error occurs
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
         System.out.println(" in servlet -----------");
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        ObjectInputStream inputFromApplet = null;
        Intermediate aStudent = null;
        BufferedReader inTest = null;
        try {         
            // get an input stream from the applet
            inputFromApplet = new ObjectInputStream(request.getInputStream());
            // read the serialized object data from applet
            data = (Intermediate) inputFromApplet.readObject();
            System.out.println("userid in servlet -----------"+ data.getUserId());
            inputFromApplet.close();
        } catch (Exception e) {
            e.printStackTrace();
            System.err.println("WARNING! filename.path JNDI not found");
        } finally {
            out.close();
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        System.out.println(" in foGet -----------");
        processRequest(request, response);
     * Handles the HTTP <code>POST</code> method.
     * @param request servlet request
     * @param response servlet response
     * @throws ServletException if a servlet-specific error occurs
     * @throws IOException if an I/O error occurs
    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        System.out.println(" in doPost -----------");
        processRequest(request, response);
     * Returns a short description of the servlet.
     * @return a String containing servlet description
    @Override
    public String getServletInfo() {
        return "Short description";
    }// </editor-fold>
}the Intermediate class ..
import java.io.Serializable;
public class Intermediate implements Serializable{
String userId;
    public String getUserId() {
        return userId;
    public void setUserId(String userId) {
        this.userId = userId;
}

Hi,
well i am not able to get any value from connection.getOutputStream() and i doubt my applet is not able to hit the servlet. could you review my code and tell me if it has some bug somewhere. and more over i want to know how to send multiple file data from applet to servlet . i want some sample or example if possible.
do share if you have any experience of this sort..
Thanks.
