Is there some code missing?
Wondering what is in util._

Thanks.

I had some stuff in util that wasn't used in the final code.

Can you check in the entire project which can be executed

That's what I have for now. Take it or leave It. Ill be providing a more robust sample app at a later date.

I will have to leave it but thanks for the reply and will look forward to the robust sample.

What's the best way of getting Salat and its dependencies onto the classpath? I'm not familiar with the way Play 2.0 interacts with SBT config.

The same way you add it to any other project: SBT is the build tool for Play 2.0

Here's my sample project's SBT Build:

import sbt._
import Keys._
import PlayProject._

object ApplicationBuild extends Build {

    val appName         = "play-mongodb-scala"
    val appVersion      = "1.0"

    val novusRels = "repo.novus rels" at "http://repo.novus.com/releases/"

    val appDependencies = Seq(
      "com.mongodb.casbah" %% "casbah" % "2.1.5-1",
      "com.novus" %% "salat-core" % "0.0.8-SNAPSHOT"
      // Add your project dependencies here,
    )

    val main = PlayProject(appName, appVersion, appDependencies).settings(defaultScalaSettings:_*).settings(
      // Add your own project settings here      
    )

}

Is there a reason you specify Casbah explicitly?
