Introduction
As you already know there are two ways of developing a web service
- Simple Object Access Protocol (SOAP)
- Representational State Transfer (REST)
Before jumping on how to create a REST based web service using Apache CXF we shall see what is REST. REST is not a technology and certainly is not a standard of some kind. It is merely an architectural style that chalks down how to write a web service in a certain way. This style was defined by a certain Roy Fielding (ring bells? yep you guessed right, he is one of the architects of HTTP) in 2000. Principal protagonist of a REST architecture is a Resource which can be uniquely identified by an Uniform Resource Identifier or URI. State of a resource at any given point of time is represented by a document and is called Representation of resource. The client can update the state of resource by transferring the representation along with the request. The new representation is now returned to client along with the response. The representation contains the information in formats like html, xml, JSON etc that is accepted by the resource. The resource which adheres to rules of REST architecture is called a RESTfull resource and web service that adheres to this rule are called RESTfull web service.
