Welcome to Atmosphere, a portable AjaxPush/Comet and WebSocket Framework for everyone. The framework support the majority of existing Webserver, and our JQuery Plugin support WebSocket (when available) and Comet (Http Streaming and long Polling)

Atmosphere is a POJO based framework using Inversion of Control (IoC) to bring push/Comet to the masses! Finally a framework which can run on any Java based Web Server, including Google App Engine, Tomcat, Jetty, GlassFish, Weblogic, Grizzly, JBossWeb and JBoss, Resin, etc. without having to wait for Servlet 3.0 Async support or without the needs to learn how Comet or WebSocket support has been differently implemented by all those Containers.  

Servlet 3.0 is supported along with framework like Cometd/Bayeux, Jersey, GWT, Wicket etc. and programming language like JRuby, Groovy and Scala. Finally, any web application can be clustered using our Cluster plugin architecture (JMS, Shoal or JGroups).

Read about why you should use Atmosphere instead of Servlet 3.0 Async

Atmosphere is also availaible as part of the following framework:

* The Atmosphere Grails Plug In
* Java Server Face via PrimeFaces
* Akka, event-driven, scalable and fault-tolerant architectures for the JVM
* Google Widget Toolkit (GWT)
