JAX-RS 2.0 - Jersey Code Rulez
By alexismp on Feb 22, 2012
This is an entirely new code base which uses HK2 for dependency injection (a core technology for GlassFish), offers a new asynchronous internal design as well as an API to programmatically define JAX-RS resources. Read about these and more about what's new in Marek's detailed post. Of course this is also the future reference implementation for JAX-RS 2.0.
Feel like trying it out? Simply go to Maven Central (of course none of this is production quality at this point).
