RESTful Webservices

REST stands for Representational State Transfer. In simple terms, REST systems do basic CRUD (Create, Read, Update and Delete) operations based on http protocol methods and communications between client and server happen over http protocol. More information can be found here.

JAX-RS specification was introduced under JSR 311 to enable J2EE applications implement REST services with ease and portability.

Few popular implementations of this specification are CXF (by Apache), RESTEasy (by JBoss) and Jersey (by Oracle).
