re: Building a stand-alone Web service with Indy - Problems with THTTPRIO URL property

2008-10-05T07:54:04-07:00

I have the same problem like Steven Barlow, with Indy 10: Everthing looks fine, the wsdl was published well, but if I want to use a real client against our server, there comes an error message in the server while handling the request: "xml document must have a top level element". I debuged and found out, that the server doesnt get the xml-request stream, he is empty (size = 0) and so the MSXML-parser sees no request SOAP-XML. At the beginning of request-handling, in IndyApp/IndyHTTP, there is the request-XML correclty, but it seemes that it got lost in "THTTPSoapPascalInvoker.DispatchSOAP" or "TSoapPascalInvoker.Invoke" ... the request stream size is zero there. The client was made by the Delphi "WSDL-importer" and is very simple, he only calls to the only server function by using the standard httprio-call. If I configure the THTTPRIO ("UseWSDL = True"), so it works with WSDLocation=True, I also get the error in the server. Very frustating ...Does anybody have a solution or a hint for me?Regards,Patrick Krause

This article is very interresting for me.The server and client function normaly, but I have a problèm ondestroy WebModule with the several Cds include.on first destroy==> okon second destroy==> error ?? procedure TWMain.WebModuleDestroy(Sender: TObject);begin if assigned(CdsBiofile) then freeAndNil(CdsBiofile); if Cds1 <> nil then freeAndNil(Cds1); if Cds2 <> nil then freeAndNil(Cds2); if Cds3 <> nil then freeAndNil(Cds3); end; I modified with other article the destroy in IndyApptdestructor TIndyApplication.Destroy;begin FServer.Free; inherited; FFactory.Free;end;but same problèm

I used this example and built my own Application. I have now a simple Exe which offers webservices on a spezial Port to other Programms. Great stuff.Building my own example I found an error in the example code. In the unit IndyApp the destroy function should be:destructor TIndyApplication.Destroy;begin FServer.Free; inherited; FFactory.Free;end;In the original the FServer.Free; is missing. On most PC's this is no big deal on an older Compaq-Server I had the problem, that after an reboot the programm didn't start again. I had to do a second reboot to solve the problem. The reason for that behaviour was, that the Webservice Port was still blocked on the network-card. With an FServer.Free; this doesn't happen.Greetings from Cologne/GermanyBernhard Ebner

Building a stand-alone Web service with Indy - Problems with THTTPRIO URL property

2002-11-27T15:50:22-08:00

I can only get this source to work with the THTTPRIO client component if I configure it using the WSDLLocation property. If I try to use the URL property of the THTTPRIO component then the SOAP Server returns an empty response. I believe the problem is something to do with the THTTPRIO component making a POST request as opposed to a GET request when the URL property is set, rather than the WSDLLocation property. The Indy HTTP server component does not seem to recieve the request details for a POST request (but this analysis could be wrong ;o) ) Has anybody else noticed this issue, and more importantly, has anybody found a solution? Cheers, Steven. PS Other than this issue the article and source is excellent and very useful.

Thanks for a great article/source. Just to let you know that all works well with ordinary WebBroker under Delphi 6 Pro (ie SOAP/Enterprise not required).

Hi Kjell.I just tried the link -- CodeCentral works for me.Here is the link:http://codecentral.borland.com/codecentral/ccweb.exe/listing?id=16364Maybe your firewall is seeing "ccweb.exe" and freaking out?What browser do you use?Thanks for writing...and good luck.J.D.P.S. Let me know if you'd like me to e-mail you the code. Reach me at jdhildebrand@borland.com.
