JAX-RS 2.0 Specification
JAX-RS provides portable APIs for developing, exposing and accessing Web applications designed and implemented in compliance with principles of REST architectural style.

The Java EE 6 release took the first step towards standardizing RESTful web service APIs by introducing a Java API for RESTful web services (JAX-RS) [JSR 311]. JAX-RS ensures portability of REST API code across all Java EE-compliant application servers. The latest version is JAX-RS 2.0 [JSR 339], which was released as part of the Java EE 7 platform.

JAX-RS focuses on applying Java annotations to plain Java objects. JAX-RS has annotations to bind specific URI patterns and HTTP operations to individual methods of your Java class. It also has annotations which can help you handle in input/output parameters.

As we already said that JAX-RS is specification; it means we need to have its implementation to run REST API code. Some of the popular JAX-RS implementations available today are:

Jersey

RESTEasy

Apache CXF

Restlet
