JAXWS RI 2.0 FCS was released last week and we are working on JAXWS 2.0.1 EA. JAXWS 2.0.1 EA is re-architected for better performance and to a greater extent a pluggable architecture that allows WSIT components such as WS-Policy, WS-Reliable Messaging etc. to plug-in both at runtime and tool time. Checkout WSIT project on java.net. Read more info on WSIT is here.

As part of this rearchitecture work MTOM implementation in JAXWS 2.0.1 EA is overhauled, re-architected and written form scratch. Feature wise its going to be the same as JAXWS RI 2.0 FCS but will be faster and more interoperable. Here are some of the key aspects of these changes:

• Streaming MTOM - uses stax-ex APIs
• Enabling MTOM using MTOM policy assertion with WSIT components
• Generation of MTOM policy assertion in the published WSDL with the WSIT components. This automatically enables MTOM interoperability with the WCF or Indigo clients.
• Fully interoperability with Microsoft WCF a.k.a. Indigo. It has been verified at WCF plugfests

I have BOF at Java One on 16th night where I will be talking about the MTOM implementation gory details and I will be happy to meet anyone interested in person and answer any question.
