紧急求助web service问题

[stonegump]

调用SOAP web service简单参数没问题，复杂类型的参数比如下面这个BuildCadDocumentRequestDto，服务端BuildCadDocumentRequestDto对象引用不为null，但requestDetail和requestHeader客户端设置后服务端仍然为null：
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "BuildCadDocumentRequestDto", propOrder = {
"requestDetail",
"requestHeader"
})
public class BuildCadDocumentRequestDto {

@XmlElementRef(name = "RequestDetail", type = JAXBElement.class, required = false)
protected JAXBElement<BuildCadDocumentDetailRequestEntity> requestDetail;
@XmlElementRef(name = "RequestHeader", type = JAXBElement.class, required = false)
protected JAXBElement<BuildCadDocumentHeaderRequestEntity> requestHeader;

谢谢先

自己顶一下，我用wsimport产生的客户端。
