我有一个Jersey服务，它通过 JAXB 将对象序列化为 XML 表示。之前在 Glassfish 上工作过，但在切换到 Jetty 后，我得到了一个

java.lang.String 不能转换为 javax.xml.namespace.QName

错误。当我搜索这种错误时，我并没有在网络上获得真正有用​​的信息。因为在我有点困惑之前它与 Glassfish 一起工作。你有想法吗？

泽西岛部分

@POST
@Path("test")
@Consumes("application/xml")
@Produces({"application/xml", "application/json"})
public DocResult returnInfo(Document dom) {

    DocResult result = new DocResult();
    List<mypackage.Document> docs = ...; // loads some documents
    result.documents = docs;
    return result;
}

要序列化的类

@XmlRootElement(name = "result")
@XmlAccessorType(XmlAccessType.FIELD)
public class DocResult {

    @XmlElementWrapper(name = "documents")
    @XmlElement(name = "document")
    public List<Document> documents;

    public DocResult() {
        documents = new ArrayList<Document>();
    }
}

这是完整的堆栈跟踪：
