Atmosphere is a POJO based framework using Inversion of Control (IoC) to bring push/Comet and Websocket to the masses! Finally a framework which can run on any Java based Web Server, including Tomcat, Jetty, GlassFish, Weblogic, Grizzly, JBossWeb and JBoss, Resin, etc. without having to learn how Comet or WebSocket support has been differently implemented by all those Containers. The Atmosphere Framework has both client (JQuery PlugIn) and server components.

Servlet 3.0 is supported along with framework like Jersey (natively), GWT (natively), Wicket, Guice, Spring etc. and programming language like JRuby, Gr oovy and Scala. We also support massive scalability with our Cluster plugin architecture (JGroups, JMS/ActiveMQ, Redis, XMPP,i etc.) Get started using the Atmosphere Whitepaper PDF and the simple JQuery Quick Start
