Everyone,

I have been tirelessly working on an applet that uploads pictures to
an apache server and subsequently writes them to a database. I have
an html equivalent that uploads them and it works fine. However, when
I try to create a POST from my Java Applet, the PHP doesn't seem to
react. The pictures never get posted to the database. Any help would
be GREATLY appreciated. Thanks to everyone in advance!

JAVA Method to send:

    /**
     * This method uploads files to the server.
     * @param url - The url to upload the files to.
     * @param files - The list of pictures to upload.
     * @throws Exception - Thrown if anything goes wrong.
     */
    public void upload(URL url, Map<BufferedImage, String> files) throws
Exception
    {
        for (BufferedImage imageSub : files.keySet()) {
            HttpURLConnection connection = null;
            try {
                //Create connection
                connection = (HttpURLConnection)url.openConnection();
                connection.setRequestMethod("POST");
                connection.setRequestProperty("Content-Type", "image/jpeg");
                connection.setRequestProperty("userfile", files.get(imageSub));

                connection.setUseCaches (false);
                connection.setDoInput(true);
                connection.setDoOutput(true);

                //Send request
                DataOutputStream wr = new DataOutputStream (
                        connection.getOutputStream ());

                ImageIO.write(imageSub, "jpeg", wr);
                wr.flush ();
                wr.close ();

                //Get Response
                InputStream is = connection.getInputStream();
                BufferedReader rd = new BufferedReader(new InputStreamReader(is));
                String line;
                StringBuffer response = new StringBuffer();
                while((line = rd.readLine()) != null) {
                    response.append(line);
                    response.append('\r');
                }
                rd.close();

                System.out.println(response);
                System.out.println(connection.getResponseCode());
            } catch (Exception e) {
                e.printStackTrace();
                System.out.println("500");

            } finally {

                if(connection != null) {
                    connection.disconnect();
                }
            }
        }
    }
