It's been a few months already that the expert group of JSR 339 started discussion about the details of JAX-RS 2.0. The target defined by spec lead Oracle are clear: Java EE 7 shall have a RESTful API that augments current JAX-RS 1.1 API by (among others) a Client API, HATEOAS support and asynchronous invocations. So what's the current status?
A lot of applications these days title themselves RESTful. But how much REST is needed to be RESTful?
Like to use XSLT 2.0 but fear to switch to SAXON? Just drop saxon9he.jar into JRE's lib/ext folder and you're done! NO FEAR, IT WILL WORK.
As it seems, Marc and Paul (the leaders of JAX-RS / Jersey) really have understood what OpenSource really means: Communicate with the community, understand their needs and thoughts, accept their ideas. I would wish that more project leaders would assimilate this open mind and welcoming kind of leadership.
