Introduction to Restful Web Services Using JAX-RS

RESTful web services are built to work best on the Web. Representational State Transfer (REST) is an architectural style that specifies constraints, such as the uniform interface, that if applied to a web service induce desirable properties, such as performance, scalability, and modifiability, that enable services to work best on the Web. In the REST architectural style, data and functionality are considered resources and are accessed using Uniform Resource Identifiers (URIs), typically links on the Web. The resources are acted upon by using a set of simple, well-defined operations. The REST architectural style constrains an architecture to a client/server architecture and is designed to use a stateless communication protocol, typically HTTP. In the REST architecture style, clients and servers exchange representations of resources by using a standardized interface and protocol.

RESTful Web Services utilize the features of the HTTP Protocol to provide the API of the Web Service. It uses the HTTP Request Types to indicate the type of operation:

GET: Retrieve / Query of existing records.
POST: Creating new records.
DELETE: Removing records.
PUT: Updating existing records.

Using these 4 HTTP Request Types a RESTful API mimics the CRUD operations (Create, Read, Update & Delete). REST is stateless, each call the to a RESTful Web Service is completely stand-alone, it has no knowledge of previous requests.

We are giving simple examples to create restful web services using JAX-RS standards.
