Scala, JSF 2, and NetBeans

I am working on a web site that will help students practice their Scala programming skills. As I labored along, writing my JSF app code, I thought “this is silly—why not practice Scala at the same time?” But I like JSF and wasn't ready to jump to Lift or Vaadin. With Eclipse, this isn't all that hard. Install the Java plugin. Make a dynamic web project in the usual way, using the Java EE perspective. Then, switch to the Scala perspective, right-click on the project, and, if all planets are aligned correctly, you will get a menu item “Add Scala nature”. (If they are not, see here for a manual approach.) Add your managed beans as Scala classes. Finally, switch back to the Java EE perspective, select the project properties, and add the Scala library JAR as a Java EE module dependency. But I like NetBeans and wasn't ready to switch to Eclipse. (Unfortunately, JSF 2 support in Eclipse is pretty minimal, the Glassfish integration is a bit flaky, and the Scala plugin has very little usable code completion.) NetBeans doesn't let me add a “Scala nature” to a web project. If I add Scala files to the project, I can edit them with the Scala editor, but they just get copied to the WAR file, without any compilation. I had one look at the Ant scripts for a Scala and a web project and decided that I wasn't going to figure out how to merge them. This blog shows how you can use Maven...
