Common WWSAPI errors: property value set incorrectly

As mentioned in my previous post , WWSAPI follows a common pattern to set properties (which in most cases are just configuration settings). Each property structure consists of three fields: id , value and valueSize . The field id is an enum value of the

When you use WsUtil to generate stub code and then work with the generated structures, you may get E_INVALIDARG when making the call to the service and, with WWSAPI tracing turned on, see the error message “ A NULL WS_STRUCT_DESCRIPTION was specified.

WWSAPI to WCF interop 11: security binding templates

In my previous post on WsUtil , I explained how the generated helper functions can simplify the creation of WS_SERVICE_PROXY and WS_SERVICE_ENDPOINT. In both of these functions, the first parameter is a pointer to a same binding template. When no security

Common WWSAPI errors: usage asserts

One of the design principles of WWSAPI is to be very stringent at the API contract, as we believe ambiguous or loose API contract does not help developers write high quality applications. Being stringent means not only to document the API contract clearly,

WWSAPI to WCF interop 10: WsUtil.exe, the silver bullet

In my previous post on interoperating with WCF BasicHttpBinding endpoint , I explained that you had to set the channel properties to match SOAP version and addressing version on the server side. Wouldn’t it be great if you don’t have to do all that? That’s

Common WWSAPI errors: addressing version mismatch

WWSAPI supports two WS-Addressing versions: the existing W3C recommendation version ( 1.0 ) and the older 2004/08 version ( 0.9 ). WS-Addressing defines a set of SOAP headers to describe the message recipient, targeted action and some other basic messaging

Common WWSAPI errors: SOAP version mismatch

There are two versions of SOAP supported by WWSAPI and most other web services stacks: SOAP 1.1 and SOAP 1.2 . Although the basic message layout in the two SOAP versions is the same (Header and Body inside Envelope), there are three main differences:

More on HTTP header authentication

My previous post on header authentication comparison between WWSAPI and WCF mentioned the impersonation level. Here is a bit more detail as people still seem to be caught by surprise due to this difference. I mentioned that WCF client could set the impersonation

WWSAPI to WCF interop 9: secure conversation bootstrapped by Kerberos AP-REQ token

In my post on WWSAPI federation support , I explained how to set up secure conversation on the WWSAPI client to work with a WCF server using WSFederationHttpBinding. In this post, I’ll show how to use secure conversation without federation. Secure conversation

Nikola asked me to write a post on how to set up machine to run our security examples. Here it goes. To run WWSAPI security examples (like the one doing Basic authentication over SSL ), you need to set up the client and server certificates for SSL and
