Come to the NovaJUG meeting on Wednesday

The Northern Virginia Java Users Group will be having a meeting at EclipseWorld from 7:00-9:00 PM on Wednesday. On the NovaJUG agenda is a presentation from Carol McDonald about dojo, REST and Comet. Here's what she'll talk about:

The goal of the Java API for RESTful Web Services (JAX-RS) is to provide a high-level declarative programming model for such services that is easy to use and encourages development according to REST tenets. Services built with this API are deployable with a variety of Web container technologies and benefit from built-in support for best-practice HTTP usage patterns and conventions.

This talk will provide an overview of the design process for a sample RESTful service using JAX-RS.

Dojo is an open source DHTML toolkit written in JavaScript.

Comet is a term to describe techniques that enable a server to push data to client browsers through an HTTP open line of communication.

• In this Presentation, we will discuss how to develop JAX-RS and dojo applications. Specifically, we will show how to develop:
• A JAX-RS application to list pet catalog items
• A dojo client to call the RESTful pet catalog and display the results
• A JAX-RS application to list slide URLs
• A dojo cometd client to call the RESTful slide service to get the slide URLs and then to call dojo cometd to publish these URLs to all clients subscribed to the slideshow channel.
