Java Play framework: Driver not found: [com.mysql.jdbc.Driver]

Dealing with the Java Play framework for the first time – I followed the instructions here:

http://www.playframework.com/documentation/2.0/ScalaDatabase  (and in a number of other Stackoverflow posts and various blogs)  

All failed to mention (or I somehow failed to read) that one has to “reload” the solution in the console after adding the database reference for the application to load the jdbc driver into the application.  Probably too obvious for regular users – but too a couple of hours for a newbe like me to figure out 🙂
