将SOAP字符串消息转换为SoapMessage的NullPointer异常

我将XML字符串转换为SOAPMessage。但是，在尝试调用服务时，我最终得到NullPointerException。当单步执行代码时，我可以告诉它正在尝试为这个uri名称空间设置一个空前缀：＆＃34; urn：oasis：names：tc：ebxml-regrep：xsd：query：3.0＆＃34;。

代码：

    //PORT_NAME={urn:ihe:iti:xds-b:2007}RespondingGateway_Port_Soap12
    //SERVICE_NAME={urn:ihe:iti:xds-b:2007}RespondingGateway_Service
        Service service = Service.create(SERVICE_NAME);
        service.addPort(PORT_NAME, SOAPBinding.SOAP12HTTP_BINDING, endpointUrl);
        Dispatch<SOAPMessage> dispatch = service.createDispatch(PORT_NAME,
                SOAPMessage.class, Service.Mode.MESSAGE);
        squashWSA(dispatch);
        addHttpHeaders(dispatch, messageId);
        //set the request timeout value
        dispatch.getRequestContext().put(JAXWSProperties.CONNECT_TIMEOUT, haimsConnectTimeout);
        dispatch.getRequestContext().put(JAXWSProperties.REQUEST_TIMEOUT, haimsReceiveTimeout);

            byte[] msgBytes = domToBytes(rawSoapRqst);
    MessageFactory mf = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);
            SOAPMessage request = mf.createMessage(new MimeHeaders(), new ByteArrayInputStream(msgBytes));
            SOAPMessage response = dispatch.invoke(request);

这结果是一个Classpath问题。我的应用程序依赖于对Xerces的传递依赖，但WebLogic wlfullclient.jar依赖已经有了JAXP。我使用了依赖＆＃34;排除＆＃34;配置删除传递Xerces依赖（groupId of＆＃34; xerces＆＃34;和＆＃34; xml-apis＆＃34;在我的代码的其他地方），问题就消失了。顺便说一句，在代码更改之前，测试是从命令行开始的，而不是从Eclipse开始。加载课程的差异可能导致不同的结果。
