This was my felling after I read this post.
In a positive way, things are changing inside Microsoft. Some years ago you would never seen some prerequisites to install like this:
Runtime: Java EE 5 on Sun Glassfish v2 + Sun WSIT/Metro (JAX-WS extensions), Tool: Netbeans 6.0 IDE.
But now Microsoft is willing to work together with their partners/competitors, struggling for a better "interoperable" world. This shouldn't be a surprise. In the past 21st of February they released a communication stating:
1. ensuring open connections
2. promoting data portability
3. enhancing support for industry standards
4. fostering more open engagement with customers and the industry, including open source communities.
If you're wondering, the above requisites are for a sample inside the R11 release of BizTalk Services that shows how to use the BizTalk Services Identity Security Token Service (STS) to secure the communication between a Java client and a Java service providing federated authentication and claims-based authorization.
Bravo Microsoft!
Until next time ;)
