Invalid fake IIxxxx.Method Interface call

Hi,

A simple service in my PC works OK(Win 7) but when I move it to a Windows 2003 server I get this exception Invalid fake IIxxxx.Method Interface call.
Is there any incompatibilities with Windows 2003 server?
It is the same executable so it must be something in the Server.
I'm running the program with Administrator Privileges.

Regards.,

Al

Re: Invalid fake IIxxxx.Method Interface call

I do not have WS 2003 at hand.
Ensure you have the latest service pack installed.

No problem with WS 2008, or Windows XP - the latest being of the same "generation" than WS 2003.

Are you using the latest 1.18 unstable version of mORMot source code?

Re: Invalid fake IIxxxx.Method Interface call

Yes, I'm using the latest source code. This is extremely weird. No antivirus, no firewall. I'm going to reinstall the server and see what happens.

Re: Invalid fake IIxxxx.Method Interface call

What is the exception?

Could you please enable logging and check the stack trace in the logs?

Ensure http.sys server (THttpApiServer class) is used.

Re: Invalid fake IIxxxx.Method Interface call

Client:

  fModel := TSQLModel.Create([], cServiceName);
  fClient := TSQLHttpClient.Create(aServer, aPort, fModel);
  fClient.Compression := [hcSynLZ, hcDeflate, hcSynShaAes];

  if not fClient.ServerTimeStampSynchronize then raise ESynConnError.Create('Servidor no disponible');
  // Si requiere Autenticación hay que autenticar antes de REGISTRAR el Servicio
  if not fClient.SetUser(aUser, aPass) then raise ESynConnError.Create('Error de autenticación');
  if not fClient.ServiceRegister([TypeInfo(IMyPrueba)], sicPerThread)
    then raise ESynConnError.Create('Servicio no disponible en el servidor');
  
  fClient.WinAPI.ReceiveTimeout := 1000

Server:

function TServicePrueba.Echo(s: RawUTF8): RawUTF8;
begin
  sleep(5000);
  Result := s;
end;

If I remove the sleep(5000) everything works fine.

By the way, how can I log to a TMemo instead of a file?

If you need it, I can send you all the source code.

Re: Invalid fake IIxxxx.Method Interface call

You set 1 second timeout on the client for a process which takes 5 seconds.
Sounds like if it works as expected!

You can log into a console directly. It is better than a TMemo IMHO.
See e.g. TForm1.btnShowLogsClick in "\SQLite3\Samples\19 - AJAX ExtJS FishFacts\Unit2.pas"

And if you use the HTTP multi-threaded server, you should better enable thread information logging.

BTW please use BBCode - see http://synopse.info/forum/help.php#bbcode - to format the code and log in your posts.

Re: Invalid fake IIxxxx.Method Interface call

What I sent you was an example. Of course I don't have 1 second timeout in the client. In the real life I had 1 minute in the client and the process took around 2 minutes when I got the error the first time. If you have any doubt just use 10 second timeout and put a delay of 20 seconds. You should double check, it is not working as expected.
