I think you are confusing the JVM with Java. However, comparing languages needed for web development to available JVM languages is comparing apples-to-oranges. With web development you have to use different languages in the same app to accomplish anything. In a app you are using the JVM for you can pick one language and stick with it.

A "facet" has absolutely nothing to do with Java. The term "facet" is a term used by IntelliJ to configure adding features to your project. IntelliJ configures all of these on its own, I never even have to think about them (it actually took me a bit to even figure out what you meant by "facet").
