Learn to REST using Jersey
By arungupta on Sep 05, 2007
Jersey is the open source JAX-RS (JSR 311) Reference Implementation for building RESTful Web services. Paul announced the availability of 0.2.1. This blog entry describe the steps to get started with Jersey and provide useful pointers for further exploration.
The bundle comes with all the required binaries (JAR dependencies) and a good set of samples for 0.2.1. Here is a consolidated list:
HelloWorld This is how everybody starts! GlassFishDB Demonstrates how to use JPA to expose the contents of a database table as a RESTful resource. JsonFromJaxb Demonstrates how to use JSON representation of JAXB-based resources. EntityProvider Demonstrates pluggable entity providers. Bookmark Demonstrates how to use JPA in the backend. Bookstore Demonstrates how to use ploymorphism with resources and views that are JSP pages. OptimisticConcurrency Demonstrates the application of optimistic concurrency to a web resource. SimpleAtomServer Simple Atom server that partially conforms to the Atom Publishing Format and Protocol SimpleConsole Demonstrates how to use the Lightweight HTTP Server included in Sun's Java SE 6.0 release. SimpleJAXWSEndpoint Demonstrates how to use a JAX-WS Endpoint. SimpleServlet Demonstrates how to use a Servlet container. StorageService Demonstrates a basic in-memory web storage service
Pick a sample, most likely "Hello World", and then follow the instructions in the main "examples" directory to run the sample.

Paul explained Why the name Jersey ? - Jersey is a restful place to spend a couple of days vacation. The Yellow jersey or Maillot jaune (the project logo) is worn by the overall leader in Le Tour. With modesty I would like this to be the leading open source project for developing RESTful Web services using plain old Java objects.
And then it could also be Java basEd RESTful Services for You as coined by Sridatta :)
