Apache Wicket – WebSocket Support

With Apache Wicket there exists a component based Web Framework which supports the new WebSocket protocol.
I want to give you a short introduction to Apache Wicket with the focus on the new WebSocket Support. It will be explained by developing a little real-time chat application in 7 steps.

As I mentioned in my previous article WebSocket versus Comet, there are good reasons using the new WebSocket protocol.
There are some Web Frameworks supporting this new protocol in their technology stack.

WebSocket versus Comet – Real-Time Web Applications


Many web application developers have tried to develop a high performance web application with real-time behaviors. A common example of such an application could be a communication web platform like a chat application. A message sent by a user should be transmitted in real-time to other users.

Years ago I tried to develop a chat web application but until now it has not been so easy to achieve. I would like to show you how easily and clearly it can be implemented today.
There will be a comparison of the different approaches to develop a real-time web application which will show that it has never been easier to achieve it before.

The approaches I want to compare are the “new” WebSocket technology and the “old” Comet approach. First you will see how difficult it was and how easy it is today to write a small communication platform. You will also get the easy and clear source code of the communication platform through the WebSocket technology. This article does not cover a complete WebSocket description but a short insight of the WebSocket technology advantages and a practical usage.
