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

If you want to do the same using Java instead of Scala you can do it in this way (this works for play framework 2.0.3):

Global.java:

import play.GlobalSettings;
import play.mvc.Result;
import play.mvc.Results;
import play.mvc.Http.RequestHeader;


public class Global extends GlobalSettings {

    @Override
    public Result onHandlerNotFound(RequestHeader request) {
        return Results.notFound(views.html.error404.render());
    }
}

Asumming that your 404 error template is views.html.error404 (i.e. views/error404.scala.html).
