Explore the different implementations of developing with Comet. See how popular Java Web servers like Jetty and Tomcat have enabled Comet applications, and learn how to program with each server. And finally, learn about the standardization proposals for Comet in Java that are part of the upcoming Servlet 3.0 and JavaEE 6 specifications.

Advanced Ajax libraries, such as jQuery, make it easy to write Comet applications on the client side, but getting them to scale on the server is still a challenge.
