Comet is a programming technique that enables web servers to send data to the client without having any need for the client to request for it. It allows creation of event-driven web applications which are hosted in the browser.
After I've blogged about ARP, I've started defining some Comet APIs on top of it. I was waiting for free time to define the perfect API. I think I was dreaming....I will never have free time with Grizzly! Since Comet Request processing is more and more popular (Jetty supports it for a while, Tomcat just have a fresh implementation...and a new NIO based connector (finally!!!), and GlassFish have ARP), I've decided to make available my own implementation. I didn't update my implementation based on Greg Wilkins' proposal, but hey, this is build on top of ARP and once the Servlet EG approves Comet support, it will be easy to implement it.
The next couple of paragraphs will introduce the API. I did the famous Chat implementation using jMaki, and will soon publish it once Greg reviewed my modifications to his jMaki application :-)
