Wsdl soap header is missing in the imported interface in Delphi 6

I am trying to implement a webservice using Delphi 6. Web service uses soap version 1.2 and my delphi has a soap agent of 1.1. When I tried to import the wsdl, soap header "Autenticacao" is missing in the interface. Provider insists to send the 4 parameters as part of this soap header before calling the web service ? I have attached both my wsdl xml file and the imported pas file ?

Can anyone help me to set the parameters of "Autenticacao" ?

Thanks in advance .

Kind Regards Sinu

I think the easiest solution would be to upgrade to a newer Delphi version, preferably Delphi XE, which has better SOAP support. Delphi 6 isn't really suitable anymore for modern development. Especially the SOAPy part...
As an alternative, you could ask someone with Delphi XE to import the service for you in XE, then migrate the code back to Delphi 6. But I fear you'd have too many incompatibilities if you'd try that.
Yet another solution would include the use of Visual Studio to create a client proxy for your Delphi application. This happens to be a solution I had to choose in the past for some project. You would use C# to create a COM-enabled assembly which you can call from your Delphi application. This assembly then executes the calls to the web service. It's an irritating work-around but when you get it working, it works quite nice too.

If you move to Delphi 7 your options improve...

The Delphi 7 WSDL Importer (wsdlimp.exe) has an update that can be downloaded from Embarcadero ID: 24535, Delphi SOAP Runtime and Importer Update

Although it doesn't say that Delphi 6 is supported (could be technical or marketing reasons behind that), you could try using the downloaded wsdlimp.exe from the command line and then try the generated .pas file with your Delphi 6 project anyway.

You can side-step the issue by altering the response XML during the RIO_AfterExecute method. Just use StringReplace to inject your header into the response, where you need it. We do something similar, but in our case we have some authentication stuff that doesn't appear in the WSDL at all, because it's not actually required by the destination service but is used by an intermediate XML gateway to authenticate the request. So we just "stuff it in there" with a stringreplace.
