Building dynamic web applications with Comet


Building dynamic web applications with Comet, dojo, and JAX-RS
Emerging Ajax techniques - variously called Ajax Push, Comet, Reverse Ajax, and HTTP streaming - are bringing revolutionary changes to web application interactivity, moving the web into the Participation Age.

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.

This talk will provide an overview of the design for a sample RESTful Collaborative Slideshow application built using JAX-RS, dojo and comet.
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 slide URLs
  • a dojo cometd client to call the RESTful slide service to get the slide URLs and then use dojo cometd to publish these URLs to all clients subscribed to the slideshow chanel.

Attendees will take away the information they need in order to add multiuser collaboration and notification features to their application. Demos and sample code will be demonstrated .
