Java 在Jaxb中获取解组异常

我使用ApacheCXF（无spring框架）实现了RESTWeb服务，对于封送，我使用了jaxb。当我在web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格式的响应解组到服务器上的对象列表中时。我得到了以下一个例外

您能提供正在尝试解组的xml吗？发布您试图解组的ABC.class和xml。

    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);
