Harold, Mike, Jiandong, Joe, Ken and myself (all from Sun) "wsited" Microsoft last week. We were just representations of the bigger team and effort scattered all over the globe (Santa Clara, Burlington, Salt Lake City, Portland, Prague, Germany, France, Bangalore). And then there were some engineers doing remote testing as well.

As mentioned earlier, WS-Addressing functionality in JAX-WSA is cleaned up and now an integral part of  JAX-WS 2.1 RI. That has been my focus for the past few weeks. So in this plug-fest, I took our JAX-WS 2.1 RI for interop on WS-Addressing test cases. Microsoft has caused a few interop problems with WS-Addressing in the past (Member Submission policy assertion namespace change, incorrect Action from WCF client, WS-Addressing WSDL namespace change). But this time everything worked, it just worked. And that's what is out-of-the-box interoperability.

Other than that, we had a good success rate doing interop on WS-Atomic Transactions, WS-Reliable Messaging, WS-Secure Conversation, WSS 1.0 and 1.1, WS-Trust. We achieved interop on composite scenarios like Secure Reliable Messaging and Secure MTOM. And this interop is two-way meaning that WCF client invoke WSIT endpoint and WSIT client invoke WCF endpoint.

We care about "I", the most, in WSIT. GlassFish v2 now integrates WSIT bits on a regular basis. When GlassFish v2 goes final, be assured it will be interoperable with .NET 3.0 framework shipping in Windows Vista and other platforms.

Read about our success stories from first and second plugfests.
