As with all things, technologies have progressed, as have other things, including the way code is shared online. So I decided it was time to update the code form that post and share it somewhere more modern.
You can now find my code for starting a Scala + Spring + Hibernate + Maven Webapp on GitHub.
At the time of writing, this project uses Scala 2.9.0-1, Spring 3.0.5.RELEASE and Hibernate 3.6.5.Final. I hope to keep it updated as new versions of these libraries are released, and also to add some more flesh to the example as time permits. (Ha!)
In you're looking more for a tutorial rather than just code, the original post still serves as a great walk-though of all the steps that went into creating the sample webapp, as well as showing lots of mistakes that I made that are probably quite common.
