Тестовый сервлет, который десериализует, потом обратно сериализует и отправляет обратно работат нормально.

protected void doPost(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws ServletException, IOException {

XMLDecoder xmlDecoder = new XMLDecoder(httpServletRequest.getInputStream());

XMLEncoder encoder = new XMLEncoder(httpServletResponse.getOutputStream());
encoder.writeObject(o);
encoder.close();
} catch (Exception e) {
e.printStackTrace(httpServletResponse.getWriter());
}
}
В другом же сервлете вылетает exception при десериализации.
