在Jaxb中获取解组异常

Question

我已经使用Apache cxf（没有弹簧框架）实现了其他Web服务，并且为了编组，我使用了jaxb。当我在网络浏览器中使用url时，一切都很好，我得到了XMl格式的对象表示，但当我使用客户端调用我的Web服务并尝试将XML格式的响应解组为我所拥有的对象列表时服务器。我收到了以下异常

我的客户端代码是

    String uri = "Path";
    URL url = new URL(uri);
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    connection.setRequestMethod("GET");
    connection.setRequestProperty("Accept", "application/xml");
    JAXBContext jc = JAXBContext.newInstance(ABC.class);
    InputStream xml = connection.getInputStream();
    ABC obj =(ABC) jc.createUnmarshaller().unmarshal(xml);
