How to expose a complex type in a Delphi WebService

Question

I've got a problem with exposing a DTO class through SOAP WebService. My class looks like TKontrahent = class public Imie : string; Nazwisko : string; Id : integer; end; Here's the Service's code: TKontrahentService = class(TInvokableClass, IKontrahentService) public function Dodaj( kontrahnet : TKontrahent) : integer; stdcall; function Aktualizuj ( kontrahent : TKontrahent) : integer; stdcall; function Usun ( kontrahent : TKontrahent) : integer; stdcall; function Nowy : TKontrahent; stdcall; end; And how the type is published in WSDL: I'd be thankful for any advices. I cannot find any sample with more complex types.

Answer 1

To expose and consume the class TKontrahent in a standard Delphi SOAP service, it must be a subclass of TRemotable and its properties must be published. As a starting point (for example after the migration from Delphi 7 to 2009) I usually import an existing WSDL to create a SOAP client and study the generated source code for classes and properties.
