REST stands for Representational State Transfer. It is a web service architecture that focuses on the system resources. Each resource is identified by a URI (Unified Resource Identifier). Accessing the resources is done using HTTP. The server reply is the representation of the resource we try to access. This representation is usually an XML document.
JSR 311 specifies Java API for REStful web services. It aims at allowing us to develop REStful web services in a standard way
