Summary
The JAX-RS API has been re-worked to enable more customization of REST services. Along with an expanded API
for creating services, a client API has been included with JAX-RS 2.0, providing another standard means for which to
create stand-alone or web clients. Features such as asynchronous processing and filters will increase the capability of
services, while making them more useable via rich clients such as those written in HTML5.
