В сервлет методом POST отсылается сериализованный c помощью XMLEncoder объект (ArrayList)
Тестовый сервлет, который десериализует, потом обратно сериализует и отправляет обратно работат нормально.

protected void doPost(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws ServletException, IOException {
try {
XMLDecoder xmlDecoder = new XMLDecoder(httpServletRequest.getInputStream());
Object o = xmlDecoder.readObject();
xmlDecoder.close();
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.

XMLDecoder decoder = new XMLDecoder(new BufferedInputStream(request.getInputStream()));
Object o = decoder.readObject();

| Код |
InputStream is = request.getInputStream();
Scanner s = new Scanner(is);
while (s.hasNext()) {
LOG.info(s.nextLine());
}
