Answer 1

@Consumes("multipart/form-data")
@Produces(MediaType.TEXT_PLAIN + ";charset=utf-8")
public String upload(MultipartFormDataInput input,  @QueryParam("videoId") String  videoId,
        @Context HttpServletRequest a_request) {

    String fileName = "";
    for (InputPart inputPart : input.getParts()) {
        try {

            MultivaluedMap header = inputPart.getHeaders();
            fileName = getFileName(header);
            // convert the uploaded file to inputstream
            InputStream inputStream = inputPart.getBody(InputStream.class, null);               
            // write the inputStream to a FileOutputStream
            OutputStream outputStream = new FileOutputStream(new File("/home/mh/Téléchargements/videoUpload.avi"));
            int read = 0;
            byte[] bytes = new byte[1024];
            while ((read = inputStream.read(bytes)) != -1) {
                outputStream.write(bytes, 0, read);
            }
            System.out.println("Done!");
        } catch (IOException e) {
            e.printStackTrace();
            return "ko";
        }

    }
