java - 如何解释 javax.xml.bind.UnmarshalException

Question

当我尝试将 xml 文件转换为其 java 对应文件时收到此错误：

09.09.2013 13:58:26 ERROR [manager.getContentsUnmarshalled():154] There was an error parsing the file: "props.xml". JAXB unmarshalling exception; nested exception is javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"newImageOverlay"). Expected elements are <{}GenericData>,<{}VirtualComponent>,<{}application_constants>,<{}channel>

我认为这个错误表示 xml 文件中存在意外元素？

在异常消息中，jaxb 如何识别“预期元素”？标识符在哪里<{}GenericData>,<{}VirtualComponent>,<{}application_constants>,<{}channel>指定？

我需要将此条目添加到我的应用程序上下文文件中：

<oxm:jaxb2-marshaller>
<oxm:jaxb2-marshaller id="marshaller">
    <oxm:class-to-be-bound name="com.MyGeneratedClass"/>
</oxm:jaxb2-marshaller>
