JAX-RS is a collection of interfaces and Java annotations that simplifies development of server-side REST applications. By using JAX-RS technology, Representational State Transfer (REST) applications are easier to develop and easier to consume when compared to other types of distributed systems.
JAX-RS is a Java API for developing REST applications quickly. While JAX-RS provides a faster way of developing web applications than servlets, the primary goal of JAX-RS is to build RESTful services. JAX-RS 1.0 defines a server-side component API to build REST applications. The IBM® implementation of JAX-RS provides an implementation of the JAX-RS (JSR 311) specification.
