JAX-RS Concepts

JAX-RS (JSR 311) is the latest JCP specification that provides a Java based API for REST Web services over the HTTP protocol. The JAX-RS specification is an annotation based server side API.

Apache Wink implements JAX-RS 1.0.

For those new to JAX-RS or developing REST applications, follow this in-progress developer guide. If you have comments or questions, send an e-mail to the appropriate Apache Wink mailing lists.

While this developer guide covers common scenarios, it is not intended to detail the JAX-RS specification itself. Please read the (brief yet understandable) specification if it is available to you.
