Many Improvements in JAX-WS 2.1 EA2: Spec, Docs and Implementation
By pelegri on Oct 24, 2006
If you are at all interested in JAX-WS you should track the changes that are happening now in the GlassFish implementation. Vivek has an Overview where he covers all the major changes while Arun Focuses on WS-Addressing and shows the substantial simplications through examples.
Check the Users Guide, and look at the list of Annotations, Async Support on the Server and Client (see blog), Stateful Web Services (also see blog). The spec changes in WS-Addressing are particularly clean; check Arun's blog.
You can download the implementation now here and install it on GlassFish or Tomcat, or wait for GF V2 b23.
