JAX-WS 2.1 RI replaced JAX-WS 2.0.1 and JAX-WSA 1.0 EA2 in WSIT approximately 2 weeks ago. This is where I've been spending most of my time during the past few weeks. With this change, WSIT is now using WS-Addressing functionality natively provided in JAX-WS 2.1 RI is used instead of relying upon a pluggable JAX-WSA 1.0 EA2. This approach has several benefits as outlined earlier. A complete description of JAX-WS roadmap will help you understand the difference between the different version numbers.

Starting with GlassFish b22, this version of WSIT is also integrated in GlassFish. So, if you download GlassFish you get WSIT, JAX-WS 2.1 and all other great stuff. This is the very first integration of JAX-WS 2.1 RI in GlassFish and most of the functionality is working. I encourage you to download GlassFish b22 and give us feedback on how we can make it better for you.
