Web services 如何将对象作为BlackBerry SOAP请求参数传递

我不熟悉使用Momentics开发黑莓。现在我想向SOAP请求发送一个对象

以下是我的web服务：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <Login xmlns="http://shidhints.com/">
      <MyLoginCredentials>
        <Email>string</Email>
        <Password>string</Password>
      </MyLoginCredentials>
    </Login>
  </soap:Body>
</soap:Envelope>

现在我得到一个错误，如：

查询失败：XML分析错误

我已经用代码解决了这个问题

QtSoapStruct *myStruct=new QtSoapStruct(QtSoapQName("MyLoginCredentials"));
myStruct->insert( new QtSoapSimpleType(QtSoapQName("Email"), email));
myStruct->insert( new QtSoapSimpleType(QtSoapQName("Password"),password));

request.addMethodArgument(myStruct);

QtSoapStruct *myStruct=new QtSoapStruct(QtSoapQName("MyLoginCredentials"));
myStruct->insert( new QtSoapSimpleType(QtSoapQName("Email"), email));
myStruct->insert( new QtSoapSimpleType(QtSoapQName("Password"),password));

request.addMethodArgument(myStruct);
