Getting Started with WebSocket and Server-Sent Events using Java by Arun Gupta

Server-Sent Events and WebSocket allow to write more interactive applications on web. It examines the efforts under way to support WebSocket in the Java programming model using JSR 356. The session also explains how Server-Sent Events can be easily written using Jersey, the Reference Implementation for JAX-RS 2. Simple "Hello World" to more elaborate Collaborative Whiteboard applications will show different features of both the technologies. A complete development using NetBeans, deployment on GlassFish, and debugging using Chrome will be shown.

This is, by far, one of the best explanations/introductions to webSockets I've evern seen.

Can you share the slides and the sample project for Server-Sent events please

[@juniorcupe7440]

good

[@tushargoel5522]

slides for presentation?

[@IndianoBrown]

That was good presentation. But I expecting more details on the resource consumption. I do understand the performance of a Websocket is great compared to REST but what about the resources like RAM. When 1000 active users have active websockets connections what happens then, where do all the connection details of the clients are stored at?

On today's systems, handling 1 million concurrent TCP connections is not an issue. Check out the answer from Alessandro Alinone on SO.
