用RO调用jave6的webservice

用RO调用jave6的webservice

java6自带webservice开发功能非常便利。那么用d调用又如何。其实也非常简单。 这里体现懒汉的优势，用ro service builder 直接生成如下：

unit SignLibrary_Intf;

{----------------------------------------------------------------------------}
{ This unit was automatically generated by the RemObjects SDK after reading  }
{ the RODL file associated with this project .                               }
{                                                                            }
{ Do not modify this unit manually, or your changes will be lost when this   }
{ unit is regenerated the next time you compile the project.                 }
{----------------------------------------------------------------------------}

{$I RemObjects.inc}

interface

uses
  {vcl:} Classes, TypInfo,
  {RemObjects:} uROXMLIntf, uROClasses, uROClient, uROTypes, uROClientIntf;

const
  { Library ID }
  LibraryUID = '{B0D81C3E-ADEA-40CC-8F17-9D8669D4FBDF}';
  WSDLLocation = 'http://192.168.1.78:8080/lavasoft.ServiceServer?wsdl';

  IServiceServerService_IID : TGUID = '{4160302F-5F1E-4424-89E8-950285727951}';

end;

{ TServiceServerService_Proxy }

function TServiceServerService_Proxy.__GetInterfaceName:string;
begin
  Result := 'ServiceServerService';
end;

function TServiceServerService_Proxy.doSomething(const doSomething: UnicodeString): UnicodeString;
var
  lMessage: IROMessage;
  lTransportChannel: IROTransportChannel;
begin
  lMessage := __GetMessage;
  lTransportChannel := __TransportChannel;
    lMessage.SetAttributes(lTransportChannel, ['InputImportedFromUrl', 'Location', 'OutputImportedFromUrl', 'SoapActionIsEmpty', 'SOAPInputNameOverride', 'SOAPOutputNameOverride', 'TargetNamespace'
      , 'Type', 'Use', 'Wsdl'],

  try
    lMessage.InitializeRequestMessage(lTransportChannel, 'SignLibrary', __InterfaceName, 'doSomething');
    lMessage.Write('doSomething', TypeInfo(UnicodeString), doSomething, []);
    lMessage.Finalize;

    lTransportChannel.Dispatch(lMessage);

    lMessage.Read('return', TypeInfo(UnicodeString), Result, []);
  finally
    lMessage.UnsetAttributes(lTransportChannel);
    lMessage.FreeStream;
    lMessage := nil;
    lTransportChannel := nil;
  end;
end;

initialization
  RegisterProxyClass(IServiceServerService_IID, TServiceServerService_Proxy);


finalization
  UnregisterProxyClass(IServiceServerService_IID);


end.

　　

=================

看调用：

procedure TForm1.Button2Click(Sender: TObject);
var
  myCoServiceServerService : IServiceServerService;
begin
  myCoServiceServerService := CoServiceServerService.Create(ROSOAPMessage1,ROWinInetHTTPChannel1);
  edt1.Text := myCoServiceServerService.doSomething('12312');
end;

procedure TForm1.Button2Click(Sender: TObject); var myCoServiceServerService : IServiceServerService; begin myCoServiceServerService := CoServiceServerService.Create(ROSOAPMessage1,ROWinInetHTTPChannel1); edt1.Text := myCoServiceServerService.doSomething('12312'); end;

====================

结果如下 ：

爽吧！

爽极了！
