JAX-RS is a key technology of the Java EE platform as REST endpoints are more and more used. Marek Potočiar (JAX-RS Co-Specification Lead) did a session during JavaOne to detail some of the proposed JAX-RS enhancements and extensions that should be part of Java EE 8. These proposals include better support for JSON (JSON-B), improved alignment between JAX-RS and CDI, enhanced support for hypermedia as well as declarative security, server-sent events, and MVC integration.
Jersey is the open source JAX-RS Reference Implementation but Jersey doesn't limit itself to the specification, i.e. Jersey has also has additional specific features. In some cases, some of the Jersey proprietary features have been standardised and added to the specification (eg. the Client API have been added to JAX-RS 2.0). So it is always interesting to check the Jersey specific extensions as some of those might be potential candidates for inclusion into a future revision of the JAX-RS specification. For example, SSE is currently supported in a Jersey specific manner but the plan is to standardised SSE support in JAX-RS 2.1. So make sure to also watch this 'What's New and Noteworthy in Jersey 2' replay that was presented by Jakub Podlešák and Miroslav Fuksa during JavaOne 2014.
