Получение ошибки при получении объекта в restful webservice

Question

Код, который использовался для преобразования моего reg_be obj в inputstream.

ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
    ObjectOutputStream oos = new ObjectOutputStream(baos); 
    oos.writeObject(reg_be); 
    oos.flush(); 
    oos.close(); 
    InputStream is = new ByteArrayInputStream(baos.toByteArray()); 

Затем я передаю этот входной поток в веб-сервис. Мой код веб-сервис

public String getText(@Context HttpServletRequest request) throws IOException { 
     // 
    Registration_BE reg_be=new Registration_BE(); 

InputStream in=request.getInputStream();

ObjectInputStream ois = new ObjectInputStream(in); 
     try { 
      reg_be=(Registration_BE) ois.readObject(); 
     } catch (ClassNotFoundException ex) { 
      Logger.getLogger(CustomerregistrationResource.class.getName()).log(Level.SEVERE, null, ex); 
     } 
} 

В сервис InputStream веб не получает правильно, почему? Этот метод работает для моего входного потока изображений. Но для этого объекта он не работает, почему? плз помогите мне ..

я получаю эту ошибку:

Answer 1

Избегайте использования сериализация для веб-сервисов - это очень ограничивает и не рекомендуется.

Используйте JSON/XML как транспортный формат, который не зависит от языка и платформы.
