I can upload my files outside of the WEB-INF folder and to the path specified but am unable to upload them into the WEB-INF folder. I hope someone can point me in the right direction. Thanks!!

IDE : Netbeans
Server : Tomacat

public void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {

            PrintWriter out =  response.getWriter();
            boolean isMultiPart= ServletFileUpload.isMultipartContent(request); // find the request object enctype
            //String uploadDirectory = "D:\\upload\\images";

            String uploadDirectory="/WEB-INF/data"; // location to upload the file
            ServletContext sc = getServletContext();
            String realPath = sc.getRealPath(uploadDirectory);

            FileItemFactory fileFactory = new DiskFileItemFactory(100,new File(uploadDirectory)); //100 is the bytes to hold in memory beyond which write the file to the directory mentioned.

            ServletFileUpload serFileUpload = new ServletFileUpload(fileFactory); //commons API to handle multipart encoding type
            try {
                List fileItems = serFileUpload.parseRequest(request);
                Iterator iter = fileItems.iterator();
                while (iter.hasNext()) {
                    FileItem item = (FileItem) iter.next();

                    if (item.isFormField()) { // identifies the normal form field , false when it identifies the upload field
                        //simply process the form fields
                        System.out.println("Text Value -->"+item.getString());
                    } else {
                            try {
                                String fileName= null;
                                if (item.getFieldName().equals("imageUpload")){
                                    if(item.getName() != null){
                                    fileName=FilenameUtils.getName(item.getName());//FilenameUtils - commons.io API
                                    item.write(new File(uploadDirectory+File.separator+fileName)); // writes the file to the upload dir
                                    RequestDispatcher rD = request.getRequestDispatcher("UnZipImage.do");
                                    rD.forward(request, response);
                                    RequestDispatcher rD = request.getRequestDispatcher("UploadForm.view");
                                    rD.forward(request, response);
                            } catch (Exception e1) {
            } catch (FileUploadException e) {

WEB-INF directory is off limit for modification from what I gathered, need to do more research.
