Building WebSockets Applications using Tomcat, Wicket and the Atmosphere Framework

Jean-Francois Arcand

Audience level:
Web Infrastructure


This session will introduce the Atmosphere Framework and show how to write WebSockets applications using Wicket and Tomcat.


This session will first discuss the new WebSockets Specification and it's current state of implementation for with browsers, libraries and servers. Second, the Atmosphere Framework will be introduced and a live Comet/WebSockets demo will be constructed using Tomcat 6 (no support for websockets) and then transparently migrated to Tomcat 7 (websockets supported). Next, the session will describe how simple it is to write powerful Wicket applications using the Wicket 6.0's Atmosphere module extension. Finally we will conclude with some performance benchmark comparing normal http vs websocket requests.
