First of all let’s examine the common code used in the examples. We will need configuration file, a library to access DB, a model to retrieve unread notification number and to add a new notification.

Binary websockets with Play 2.0 and Scala (and a bit op JavaCV/OpenCV) | Smartjava.org

Binary websockets with Play 2.0 and Scala (and a bit op JavaCV/OpenCV) | Smartjava.org | playframework | Scoop.it

In a recent article I showed how you can use webrtc, canvas and websockets together to create a face detection application whose frontend runs completely in the browser, without the need for plugins. In that article I used a Jetty based backend to handle the image analysis using OpenCV through the JavaCV wrapper.
When I almost finished the article, I noticed that websockets is also supported from Play 2.0. I really like developping in Play and in Scala so as an experiment I rewrote the backend part from a Jetty/Java/JavaCV stack to a Play2.0/Scala/JavaCV stack. If you want to do this for yourself, make sure you start with the frontend code from here. Since the frontend code hasn't changed except the location where the websockets are listening.

Vous avez certainement entendu parler d’Ajax et de Comet. Nous allons voir avec un exemple complet, codé et déployé sur Heroku en une journée, comment cela fonctionne. Au passage je vais aussi vous parler de Play2, l’un des rares frameworks webs à proposer un modèle de programmation évenementiel. Cela vient du monde Haskell et c’est un petit bijou. S’il y a un cas d’usage de Play2 qu’il faut retenir : ça roxe du poney pour coder une application web temps réel.
