How to create a custom 404 page handler with Play 2.0?

Question

What’s the preferred way to handle 404 errors with Play 2.0 and show a nice templated view?

Answer 1

This works in 2.2.1. In Global.java:

public Promise onHandlerNotFound(RequestHeader request) {
    return Promise.pure(notFound(
        views.html.throw404.render()
    ));
}

Ensure that you have a view called /views/throw404.scala.html
