Writing Comet Applications Using JRuby and the Atmosphere Framework

Writing Atmosphere's Comet based applications is simple. Imagine using JRuby instead of Java...it becomes really simple!. As with Scala, it is also possible to write Comet application with Atmosphere Framework using JRuby. A user of Atmosphere recently posted the famous chat application written using JRuby and an embedded instance of Jetty. I've decided to write the same application using the Atmosphere Spade Server, which build on top of Jersey and Grizzly (will soon support Netty and Jetty). The idea behind the Atmosphere Spade Server is to make it really simple to test and embed your Comet application. Note that any application written using the Atmosphere Spade Server is portable, e.g. it will also deploy into any Servlet Container like Tomcat, Glassfish, Weblogic etc. Before jumping into JRuby, let's just explore the Atmosphere Spade Server main class, AtmosphereSpadeServer: public static AtmosphereSpadeServer.build(String uri); Invoking that simple method will automatically creates, under the hood, a Grizzly Servlet Container instance ready to receive requests based on the URI entered AtmosphereSpadeServer.build("http://localhost:8080/") Next step is to add your Atmosphere POJO aka AtmosphereHandler (I recommend you read that post for more details about
