File Upload using the JQuery and spring

File Upload function using the JQuery

 The below function can used for the upload a file using jquery.

For large files it may show error like script execution take more time and some times its hanges.

$(document).on('change', '.uploaddocument', function() {

                var oMyForm = new FormData();

                oMyForm.append("file", this.files[0]);

                $.ajax({

                  url: 'uploaddocument.html',

                  data: oMyForm,

                  dataType: 'text',

                  processData: false,

                  contentType: false,

                  type: 'POST',

                  success: function(data){

                  }

                });

       });

its works fine from IE9 only. 

The above code for the jsp part. for the backend process gone through the below code.
 The example implemented using spring 3.24 version.

@RequestMapping(value = "/uploadimages", method = RequestMethod.POST)

    public ModelAndView uploadimages(MultipartHttpServletRequest request,

            HttpServletResponse response) {

        Iterator<String> itr = request.getFileNames();

        MultipartFile mpf = request.getFile(itr.next());

        try {

            if (mpf.getOriginalFilename() != null

                    && !"".equals(mpf.getOriginalFilename())) {

                ufile.setLength(mpf.getBytes().length);

                ufile.setBytes(mpf.getBytes());

                ufile.setType(mpf.getContentType());

                ufile.setName(mpf.getOriginalFilename());

                File file = new File(request.getSession().getServletContext()

                        .getRealPath("/") + UPLOADED_IMAGES);

                if(!file.exists()){

                    file.mkdir();

                }

                file = new File(request.getSession().getServletContext()

                        .getRealPath("/")

                        + UPLOADED_IMAGES

                        + File.separator

                        + mpf.getOriginalFilename());

                FileUtils.writeByteArrayToFile(file, mpf.getBytes());

                request.setAttribute(IMG,UPLOADED_IMAGES + "/" + mpf.getOriginalFilename());

            }

        } catch (IOException e) {

            rapidLogger.errorMessage(IO_EXCEPTION, e);

        }

        return new ModelAndView(CAPTURE_PHOTO);

    }
