Adding a Scala Module to an Existing Java Project

So I have a pretty big game! project using standard Java material. I want to start using Scala and thought I could combine the two. I installed the Scala module and added a configuration line. Then I added a new controller:

package controllers

import play.mvc._

object Blog extends Controller {
  def index = "test"
}

But when I restart the server and try to go to http: // localhost: 9000 / Blog / index , I get a "Blog.index action not found"

Is there anything else I need to do to add Scala support for this project, or do I need to create a new project using Scala from get go and copy all the files?

UPDATE

routes:
