Java API for RESTful Web Services (JAX-RS)

The Java API for RESTful Web Services (JAX-RS) defines APIs for the development of Web services built according to the Representational State Transfer (REST) architectural style. A JAX-RS application is a web application that consists of classes that are packaged as a servlet in a WAR file along with required libraries.

The JAX-RS API is new to the Java EE 6 platform.
