Delphi程序访问AXIS的Web Service服务问题求助?

[test422]

在Axis上用Java写的Web Service,在应用程序中调用很正常.
但是用Delphi调用就出现错误,错误类型"类型错误"?
那位大侠帮一下!代码如下:
procedure TForm1.Button1Click(Sender: TObject);
var
MyHello : Hello;
SoapRio : THTTPRio;

name : widestring;
myname : widestring;
begin
SoapRio := THTTPRio.Create(nil);

SoapRio.HTTPWebNode.UseUTF8InHeader := true;
SoapRio.WSDLLocation := 'http://localhost:8080/axis/TestWSDL.wsdl';
SoapRio.Service := 'HelloService';
SoapRio.Port := 'Hello';

myname := 'test';
MyHello := SoapRio as Hello;
myname := edit1.Text;
MyHello.hello(myname, name);


SoapRio.Free;
end;

以解决!
