In my application I am running an applet to scan a picture from client. I need to upload the scanned file to the server then to database. I can upload the file by submitting a form in JSP, but I need the applet to post the file to URL.

Any hep would be appreciated.

Here is the code:

public static void main(String[] args) throws Exception {

    URL url = new URL("http://localhost:8080/spring/upload");
    URLConnection connection = url.openConnection();
    connection.setDoOutput(true);

    connection.setRequestProperty("Content-Type", "text/html;charset=UTF-8");
    connection.setRequestProperty("enctype", "multipart/form-data");

    DataOutputStream printout = new DataOutputStream(
        connection.getOutputStream());
    printout.write(FileUtils.readFileToByteArray(new File("c:\\img_khar.jpg")));

    printout.flush();
    printout.close();

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

    String decodedString;

    while ((decodedString = in.readLine()) != null) {
        System.out.println(decodedString);
    }
    in.close();
}
