In a related article published here
in eweek, a quote from the article says "The
companies' cooperation will soon give developers freedom to work with Web
services partners using Microsoft's Windows Communication Foundation (formerly
"Indigo") or JAX-WSA (Java API for XML Web Services Addressing)."
Although I fully agree with Peter that this cooperation between the two
companies will provide flexibility to work with either of the framework. But
here WCF is incorrectly compared
to JAX-WSA. The latter provides an API
to enable WS-Addressing support in Java platform and is just one of the multiple
specifications supported by WSIT. Instead
WCF should be correctly compared to WSIT. I've already emailed a correction to
the editor and hopefully will hear back soon.
