Question

我们有一个web服务，其实现在.net中完成。我们从java调用这个web服务。 web服务在大多数情况下都完全正常，但有时它会抛出IllegalArgumentException。

webservice有两个名为pointEnquiry和pointEarnedEnquiry的方法。这两种方法都有一个参数，如pointEnquiryResult和pointEarnedEnquiryResult。响应包装器分别是PointEnquiryResponse和PointsEarnedEnquiryResponse。

面临的问题是抛出IllegalArgumentException，状态无法将PointEnquiryRespone.pointEnquiryResult设置为PointEarnedEnquiryResponse。

此外，这两种方法的返回类型都是JAXBElement。

我无法理解与包装类相关的返回类型是什么以及为什么pointEnquiryResult在它不属于该类时尝试将自身映射到PointEarnedEnquiry响应。

请找到堆栈跟踪

以下是用于调用Web服务的代码。它使用RPC样式通信。

public PlayerPointsEnquiryParameter pointEnquiry(String playerId) throws Exception {
    PlayerPointsEnquiryParameter playerPointsEnquiryParameter  =null;
    try {
        if(iPointsEnquiry == null){
            URL wsdlURL = new URL(SWSUtility.getCMPPointEquiryURL());
            if(logger.isDebugEnabled()){
                logger.debug("URL invoked : " + wsdlURL.toString());
            }
            Service service = Service.create(wsdlURL,_cmpPointEnqiry_QNAME);
            iPointsEnquiry = service.getPort(IPointsEnquiry.class);
        }

        playerPointsEnquiryParameter  = iPointsEnquiry.pointEnquiry(playerId);
        if(logger.isDebugEnabled()){
            logger.debug("playerPointsEnquiryParameter"+ playerPointsEnquiryParameter);
        }
    } catch (MalformedURLException e) {
        iPointsEnquiry = null;
        logger.error("Malformed URL", e);
        throw e;
    } catch (Exception e) {
        iPointsEnquiry = null;
        logger.error("Exception @", e);
        throw e;
    }
    return playerPointsEnquiryParameter;
}

public PlayerPointsEnquiryParameter pointEarnedEnquiry(String partonID, GregorianCalendar dtStartDate, GregorianCalendar dtEndDate ) throws Exception {

    try {
        XMLGregorianCalendar calenderdtStartDate = DatatypeFactory.newInstance().newXMLGregorianCalendar(dtStartDate);  
        XMLGregorianCalendar calendedtEndDater = DatatypeFactory.newInstance().newXMLGregorianCalendar(dtEndDate);
        if(iPointsEnquiry == null){
            URL wsdlURL = new URL(SWSUtility.getCMPPointEquiryURL());
            if(logger.isDebugEnabled()){
                logger.debug("URL invoked : " + wsdlURL.toString());
            }
            Service service = Service.create(wsdlURL,_cmpPointEnqiry_QNAME);
            iPointsEnquiry = service.getPort(IPointsEnquiry.class);
        }

        playerPointsEnquiryParameter  = iPointsEnquiry.pointEarnedEnquiry(partonID, calenderdtStartDate, calendedtEndDater);
        if(logger.isDebugEnabled()){
            logger.debug("playerPointsEnquiryParameter"+ playerPointsEnquiryParameter);
        }
    } catch (MalformedURLException e) {

        iPointsEnquiry = null;
        throw e;
    }
    return playerPointsEnquiryParameter;
}

以下是实施

public abstract interface IPointsEnquiry
{
  @WebMethod(operationName="PointEnquiry", action="http://www.hhtechno.com/KioskPointsEnquiry/IPointsEnquiry/PointEnquiry")
  @WebResult(name="PointEnquiryResult", targetNamespace="http://www.hhtechno.com/KioskPointsEnquiry")
  @RequestWrapper(localName="PointEnquiry", targetNamespace="http://www.hhtechno.com/KioskPointsEnquiry", className="com.hhtechno.kioskpointsenquiry.PointEnquiry")
  @ResponseWrapper(localName="PointEnquiryResponse", targetNamespace="http://www.hhtechno.com/KioskPointsEnquiry", className="com.hhtechno.kioskpointsenquiry.PointEnquiryResponse")
  @Action(input="http://www.hhtechno.com/KioskPointsEnquiry/IPointsEnquiry/PointEnquiry", output="http://www.hhtechno.com/KioskPointsEnquiry/IPointsEnquiry/PointEnquiryResponse")
  public abstract PlayerPointsEnquiryParameter pointEnquiry(@WebParam(name="strPlayerId", targetNamespace="http://www.hhtechno.com/KioskPointsEnquiry") String paramString);


  @WebMethod(operationName="PointEarnedEnquiry", action="http://www.hhtechno.com/KioskPointsEnquiry/IPointsEnquiry/PointEarnedEnquiry")
  @WebResult(name="PointEarnedEnquiryResult", targetNamespace="http://www.hhtechno.com/KioskPointsEnquiry")
  @RequestWrapper(localName="PointEarnedEnquiry", targetNamespace="http://www.hhtechno.com/KioskPointsEnquiry", className="com.hhtechno.kioskpointsenquiry.PointEarnedEnquiry")
  @ResponseWrapper(localName="PointEarnedEnquiryResponse", targetNamespace="http://www.hhtechno.com/KioskPointsEnquiry", className="com.hhtechno.kioskpointsenquiry.PointEarnedEnquiryResponse")
  @Action(input="http://www.hhtechno.com/KioskPointsEnquiry/IPointsEnquiry/PointEarnedEnquiry", output="http://www.hhtechno.com/KioskPointsEnquiry/IPointsEnquiry/PointEarnedEnquiryResponse")
  public abstract PlayerPointsEnquiryParameter pointEarnedEnquiry(@WebParam(name="strPlayerId", targetNamespace="http://www.hhtechno.com/KioskPointsEnquiry") String paramString, @WebParam(name="strStartDate", targetNamespace="http://www.hhtechno.com/KioskPointsEnquiry") XMLGregorianCalendar paramXMLGregorianCalendar1, @WebParam(name="strEndDate", targetNamespace="http://www.hhtechno.com/KioskPointsEnquiry") XMLGregorianCalendar paramXMLGregorianCalendar2);
}

我遇到的问题是其中一个线程让我们说t1正在调用方法pointEnquiry并等待响应。同时，另一个线程t2进入图片并调用pointsEarnedEnquiry。几秒钟后，线程t1抛出IllegalArgumentException，如上所述。

我检查了服务器端，对于线程t1发出的请求，生成并发送了适当的响应。

我的问题：

由于Web服务中两个web方法的返回类型相同，即PlayerPointsEnquiryMethod，我在客户端没有进行任何类型的解包，为什么我会得到一个例外

无法将javax.xml.bind.JAXBElement字段com.hhtechno.kioskpointsenquiry.PointEarnedEnquiryResponse.pointEarnedEnquiryResult设置为com.hhtechno.kioskpointsenquiry.PointEnquiryResponse。
两种方法的不同之处在于Request和Response Wrappers。虽然pointsEnquiry将ResponseWrapper作为PointsEnquiryResponse，但pointsEarnedEnquiry将ResponseWrapper作为PointsEarnedEnquiryResponse。必须有一些东西指示unmarshaller打开对PointsEarnedEnquiryResponse或PointsEnquiryResponse的响应。如果我在这里错了，请指导我。
代码大部分时间都能正常工作，它只抛出IllegalArgumentException几次。这是否与某些缓存问题有关？

请求社区的帮助，因为我已经尝试了很多，并且处于如何进行的死胡同。

调用webservice
