Consuming WebServices in combination with oAuth2.0


17+ years progress programming and still learning.
Working on a new project that requires consuming WebServices (WSDL, not REST). However, I need to include some extra information in the HTTP Headers for the access token. But the ABL does not expose any methods with adding extra HTTP headers.

Apart from using sockets or OPENEDGE.HTTP.NET.PL and posting the SOAP payload myself, what are the alternatives??

Since the ABL does not support the SSL client certificate I use the .NET HttpWebRequest object. Obviously our client is running on Windoze.

On Solaris we use wget.

Can you explain a bit more about SSL client Certificate support issue, is that about using CA x.509 certificates??

Do you have any sample ABL code which uses NET HttpWebRequest>
The ABl (at least with OE 11.6) does not support the SSL client certificate except for WebService calls. With standard HTTPS get and post requests you cannot use it. Here @ my employer we all login to our Windows 7 systems with a smartcard. During login to Windows the SSL client certificate residing on the smartcard is copied into Windows certificate store. Our single-sign-on infrastructure is based in CAs SiteMinder and each web server requests the SSL client certificate to be present for authentication.

Is there something extra I need to add to the assemblies .xml file?

I've added Sytem,Security just to "suck it and see", but that did not work.
The auth.ClientCertificate is a class which I developed to wrap the logic which fetches the SSL certificate from the Windows certificate store. I did not include it. Do you need a sample on how to get the certificate from the Windows certificate store?
