Problem Calling PI 7.0 Webservice from .NET

[Former Member]

Hi,

We are having difficulties while calling a webservice in PI from .net environment. Scenario is SOAP to RFC. I am using Altova to test the service, there seems no problem. However return of web service call is "null" if I use .NET to call it. I mean "res" object below which refers returning data type of the service is completely null

WRefBelnoMal.DT_Sonuc res = new TransferPosting.WRefBelnoMal.DT_Sonuc();

res = BelnoService.MI_OB_SBP_BelNOMalHar(req);

I installed tcpgateway to observe the messages travelling and saw that the response is actually coming to my machine. It seems a .NET problem to me but I want to be sure.

Any idea about the source of error?

Tarik,

If Altova allows you to succesfully invoke the web service and see the response and you also see the response when viewing the HTTP traffic, I think this is indeed a clear indication that the problem is with .net and not with PI.

Kind regards,
