Questions using a .NET webservice with a client certificate required ASP page.

[jwillams77]

I have searched extensively though Google and Experts Exchange and have not quite found the answer to this problem.

Here is the scenario:

I have a .NET 2.0 c# web service that is installed under a path on our server that requires a client certificate to reach both the service and the website that will use the service. The website however is in classic ASP, so I am having to use MSSOAP 3.0 to call the service from the ASP page. Here is the code on the ASP page:

Dim oSOAP
Set oSOAP = Server.CreateObject("MSSOAP.SoapClient30")
oSOAP.ClientProperty("ServerHTTPRequest") = True
oSOAP.mssoapinit("https://www.e-statement.net/web_parser/service.asmx?wsdl")

guidname1 = oSOAP.GetXMLField(guidstring, "Name1")
guidname2 = oSOAP.GetXMLField(guidstring, "Name2")
guidaddress1 = oSOAP.GetXMLField(guidstring, "Address1")
guidaddress2 = oSOAP.GetXMLField(guidstring, "Address2")
guidcity = oSOAP.GetXMLField(guidstring, "City")
guidstate = oSOAP.GetXMLField(guidstring, "State")
guidzip = oSOAP.GetXMLField(guidstring, "Zip")
guidhomephone = oSOAP.GetXMLField(guidstring, "HomePhone")
guidworkphone = oSOAP.GetXMLField(guidstring, "WorkPhone")
guidssn1 = oSOAP.GetXMLField(guidstring, "SSN1")
guidssn2 = oSOAP.GetXMLField(guidstring, "SSN2")
guiddln1 = oSOAP.GetXMLField(guidstring, "DLN1")
guiddln2 = oSOAP.GetXMLField(guidstring, "DLN2")

oSoap = Nothing


Here is the error message I'm receiving:

WSDLReader:XML Parser failed at linenumber 0, lineposition 0, reason is: A connection with the server could not be established HRESULT=0x1: Incorrect function. - WSDLReader:Loading of the WSDL file failed HRESULT=0x80070057: The parameter is incorrect. - Client:One of the parameters supplied is invalid. HRESULT=0x80070057: The parameter is incorrect.

A quick look at the event veiwer on the Server shows that the request can not access the wsdl file. Is this because the path in the ASP page is using the URL requiring the client certificate and the Server itself does not have the certificate?

I have figured out the issue I was having. The issue was the IP address of the URL strings.


First I went ahead and made a virtual directory and placed the webservice onto a IP address on our webserver not requiring the client certificate. This allowed the webpage which does require the certificate to access the service for XML parsing.

Once I change the following line:
oSOAP.mssoapinit("https://www.myURL/web_parser/service.asmx?wsdl")


to

oSOAP.mssoapinit("http://IPA.DDR.E.SS/webservice/service.asmx?wsdl")

The XML document was parsed correctly and the values I needed were placed in the correct HTML objects for the Order Entry website in classic ASP

Actually I think what solved the problem is that you changed HTTPS to HTTP.

I have the same problem with using SSL to connect ancient ASP to ASP.NET 2.0 webservice using SOAP 3 toolkit.

There is a ms kb here which gives some info regarding installing the client certificate for the website into a certificate store that is available to all users (including the IUSR account).

I could not get this working.

Hi there. Did you ever find an answer to this? I am seeing on other posts that it is a proxy issue, the odd thing for me is that it works sometimes and not others. That is driving me nuts since I know it is not a code issue, but do not know if it is an issue on my web server's end or on the end of the company with the web service I am trying to call.

Let me know - thank you!
