عمل فورمة بروفايل للمستخدم

السلام عليكم ورحمة الله و بركاته

انا عندي صفحة servlet & JSP

وبحاول اعمل فورمة ابولد لصورة مع نص كتابي كالوصف مثلا

لكن المشكلة اني عندما احاول احضار المتغيرات في ال Servlet باستخدام request.getParameter

تظهرلي مشكلة و هي انها تكون ب Null

وبعد البحث وجدت اني عندما اضع Annotation

@MultiPartConfig

قيم المتغيرات تكون مقرؤة عادي جدا

لكن هنالك مشكلة جديدة ظهرت و هي انه في كود الابلود يدخل في لووب غير منتهي حتي مع زيادة المتغير كل مرة

وها هو الكود :

@MultipartConfig
public class upl 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 {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        try {
            request.setCharacterEncoding("UTF-8");
            response.setCharacterEncoding("UTF-8");
            //-------------------------------------
//            Part imageLinkPart = request.getPart("imageLink");
//            Scanner scanner = new Scanner(imageLinkPart.getInputStream());
//            String imgLink = scanner.nextLine();
//            //-------------------------------------
//            MultipartParser mp=new MultipartParser(request, 1*1024*1024);
            String imageDescription = request.getParameter("imageDesc");
            String imageLink = request.getParameter("imageLink");

            //to get the content type information from JSP Request Header
            String contentType = request.getContentType();
            //here we are checking the content type is not equal to Null and as well as the passed data from mulitpart/form-data is greater than or equal to 0
            if ((contentType != null) && (contentType.indexOf("multipart/form-data") >= 0)) {
                DataInputStream in = new DataInputStream(request.getInputStream());
                //we are taking the length of Content type data
                int formDataLength = request.getContentLength();
                byte dataBytes[] = new byte[formDataLength];
                int byteRead = 0;
                int totalBytesRead = 0;
//================================================================
  هذه هي اللووب غير المنتهية  
   //this loop converting the uploaded file into byte code
                while (totalBytesRead < formDataLength) {
                    byteRead = in.read(dataBytes, totalBytesRead, formDataLength);
                    totalBytesRead += byteRead;
                }
                SQLOperations.connect();
                String file = new String(dataBytes);
                //for saving the file name
                String saveFile = file.substring(file.indexOf("filename=\"") + 10);
                saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
                saveFile = saveFile.substring(saveFile.lastIndexOf("\\") + 1, saveFile.indexOf("\""));
                int lastIndex = contentType.lastIndexOf("=");
                String boundary = contentType.substring(lastIndex + 1, contentType.length());
                int pos;
                SQLOperations.insertImageName(saveFile, imageDescription, imageLink);
                //extracting the index of file 
                pos = file.indexOf("filename=\"");
                pos = file.indexOf("\n", pos) + 1;
                pos = file.indexOf("\n", pos) + 1;
                pos = file.indexOf("\n", pos) + 1;
                int boundaryLocation = file.indexOf(boundary, pos) - 4;
                int startPos = ((file.substring(0, pos)).getBytes()).length;
                int endPos = ((file.substring(0, boundaryLocation)).getBytes()).length;

                // creating a new file with the same name and writing the content in new file
                String fileLocation = "C:\\Users\\M\\Music\\Documents\\NetBeansProjects\\Templ\\web\\upl\\" + saveFile;
                FileOutputStream fileOut = new FileOutputStream(fileLocation);
                fileOut.write(dataBytes, startPos, (endPos - startPos));
                fileOut.flush();
                fileOut.close();
                SQLOperations.disconnect();
                response.sendRedirect("showImage.jsp");

            }
//             else{
//                String error ="nullImage";
//                response.sendRedirect("upload.jsp?error='"+error+"'&&imgDesc='"+imageDescription+"'");
//            }
        } finally {
            out.close();
        }
    }
