What's Going On with WSIT?
The Web Services Security feature of OpenSSO implements the Web Services Interoperability Technology (WSIT). WSIT is an open source implementation of the web services specifications (commonly referred to as WS-*). The project was started by Sun Microsystems, and consists of Java API that allow developers to create web service clients and services that enables operations between the Java platform and clients and servers developed with the WS-* specifications.
