Problem in enctype="multipart/form-data" in JSP

im using a page which is in JSP. i have some text boxes and one upload button. i want to load the file itself when i click the submit button. im using enctype="multipart/form-data" in this form. i also using the commons-fileupload-1.2.2.jar file for getting the uploaded value. but the problem is the uploaded file is not stored in the prefered folder. i printed the path it shows correctly.

here the code,

the form is post method, and enctype="multipart/form-data"

here the code,

boolean isMultipart = ServletFileUpload.isMultipartContent(request); if (!isMultipart) { out.print("No multipart");

} else {

      FileItemFactory factory = new DiskFileItemFactory();
      ServletFileUpload upload = new ServletFileUpload(factory);
      List items = null;

      try {

         items = upload.parseRequest(request);

         } catch (FileUploadException e) {

             e.printStackTrace();
          }
          Iterator itr = items.iterator();

          while (itr.hasNext()) 
          {
              FileItem item = (FileItem) itr.next();

              if (!item.isFormField()) {
                                    try {

                      String itemName = item.getName();
                      File savedFile = new File(config.getServletContext().getRealPath("/")+"emp_image\image\"+itemName);


                     item.write( savedFile);
                       out.print("<br>"+savedFile);    
                  } catch (Exception e) {

                      e.printStackTrace();
                  }



              } else {

                     String name = item.getFieldName();
              String value = item.getString();
                       }

the savedFile prints the path. and i also created the required folders. but the uploaded image is not present in the folder.

Help me to solve this problem.
