java调用webservice payload方式，求大佬哪个大佬看看

Question

java调用webservice代码片段

StreamSource xmlSource = new StreamSource(new StringReader(soapBody));  
        URL wsdlURL = new URL(wsdlUrl);  
        QName serviceQName = new QName(targetNamespace, serviceName);  
        Service service = Service.create(wsdlURL, serviceQName);  

        //创建port端口及 Dispatch<Source>对像  
        QName portQName = new QName(targetNamespace, portName);  
        Dispatch<Source> dispatch = service.createDispatch(portQName, Source.class, Service.Mode.PAYLOAD);  
        Source orderSource = dispatch.invoke(xmlSource);

走到这一步
Source orderSource = dispatch.invoke(xmlSource);
报错：

不知道什么原因，用TEST跑这段代码没问题

Answer 1

xmlSource这个返回的xml数据可能有问题，可以debug或者打印log看下是不是返回空的或者不正确格式的xml
