This is the Play 2 project accompanying my presentation called "Core Play". It contains all the sample code in the slides, and serves as a starting point for the 'Hands On' session.
The presentation itself can be found on http://eamelink.net/2012/06/core-play-2-presentation.html
This is just an SBT application; you don't need Play 2. You do need SBT 0.11.2 though, or update
project/build.properties for 0.11.3 if you have that version.
sbt run, and browse to http://localhost:9000/
For the WebSocket test-screen, browse to http://localhost:9000/
