A couple weeks ago, Microsoft was at ApacheCon. We reported the progress made on the Stonehenge project and presented the roadmap.
The goal of Apache Stonehenge is to provide a public forum to test the interoperability of WS-* protocols on different vendor stacks and to build sample applications that could provide best practices and coding guidelines for better interoperability. The main sample application, StockTrader has been implemented on .NET (by Microsoft), PHP (by WSO2), WSAS JAVA stack (by WSO2), Metro (by SUN Microsystems), Spring (by SpringSource). The latest version of StockTrader uses the WS-Security and WS-Trust protocols for claims-based authentication scenarios. This allows the end-users to be authenticated through an independent Security Token Service (STS) that is trusted by the bank and to pass that token to the broker to process the transaction.
