NetBeans offers some shortcuts for code navigation. Click the mouse pointer onto a method name (or focus the name by keyboard) and press Alt-F7. This finds all usages of this method.

Focus the usage of any method and press Ctrl-B takes you to the definition of this method.

So far, this is just behavior of a good Java editor. But what about Java EE?

Java EE covers JSF as web frontend technology. Within your webpages you may use methods. Ctrl-B takes you from such a usage within your (X)HTML directly to the Java definition. And Alt-F7 on the Java method finds the usages within your pages.

Enjoy!
