protected void doPost(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
           String relativeWebPath = "/image";
    String absoluteFilePath = getServletContext().getRealPath(relativeWebPath);
    if (ServletFileUpload.isMultipartContent(request)) {
        try {
            List<FileItem> multiparts = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
            for (FileItem item : multiparts) {
                if (!item.isFormField()) {
                    String name = new File(item.getName()).getName();
                    item.write(new File(absoluteFilePath + File.separator + name));
                }
            }
            request.setAttribute("message", "File Uploaded Successfully");
        } catch (Exception e) {
            request.setAttribute("message", "File Upload Failed due to " + e);

        }
    } else {
        request.setAttribute("message",
                "Sorry this Servlet only handles file upload request");
    }
    request.getRequestDispatcher("result.jsp").forward(request, response);
