Building RESTful Web Services in

JerseyJersey is an open source, JAX-RS(JSR 311) Reference

Implementation for building RESTful Web services.

Jersey is more than a Reference Implementation because itprovides anAPIso that developers may extend Jersey tosuit their needs.

Google App EngineRun your web apps on Google's infrastructure:

Easy to build

Easy to maintain

Easy to scale

Focus on your app, leave the rest to Google Zero to sixty: App Engine enables your application to scale automatically

without worrying about managing machines.

You're in control: The simple, web-based dashboard makes it easy tomanage your application without having to babysit it.

Google offers a Eclipseplugin that provides both Google App Engine

and GWTdevelopment capabilities. Install theplugins fromhttp://dl.google.com/eclipse/plugin/3.7via the Eclipse updatemanager.

Run Applications LocallyThe Eclipse Plugin allows to run applications for the

Google App Engine

locally in an environment which simulates the

environment on the App Engine.

You also have a local admin console(http://localhost:8888/_ah/admin/) which

allows you to see: your local datastore

the task queue,

inbound email and XMPP traffic.

Run Applications in Google CloudTo create an application on the Google App Engine, create an

application on

the Google App Engine website (https://appengine.google.com/).

Afterwards you can locally create an web application and uploadthis

application to the created application on the Google App Engine.

To create an application on theApp Engine press the button"Create an application" and select an application name. You have to

choose one which is still available.
