What are RESTful Web Services?
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.

Creating a RESTful Resource Class
Root resource classes are POJOs (Plain Old Java Objects) that are either annotated with@Path or have at least one method annotated with@Path or a request method designator such as @GET, @PUT, @POST, or @DELETE. Resource methods are methods of a resource class annotated with a request method designator. This section describes how to use Jersey to annotate Java objects to create RESTful web services.

The Storage-Service Application
The Storage-Service sample application demonstrates a simple, in-memory, web storage service and test code using the Jersey client API. The web storage service enables clients to create and delete containers. Containers are used to create, read, update, and delete items of arbitrary content, and to search for items containing certain content. A container can be thought of as a hash map of items.

RESTful Webservice Best Practices
Provide a distinct URI for each resource you wish to expose.
Use nouns in your URIs, they highlight the fact that resources are things and not actions.
Methods that map to GET should not change any data.
Methods that map to POST should change the data.
Make your service stateless.
