JavaFX is a cross-platform runtime environment introduced by Sun Microsystems with the intent of building rich Internet applications across different kinds of devices. It is not only intended to be used on Desktop, but also to be deployed on set-top boxes, cell phones, TVs, and more.
With the upcoming release of JavaFX 2.0, Oracle will be porting all of the APIs that once were available under JavaFX Script into the Java language. This will make JavaFX more familiar to those who already know Java. The new version will also make it easier to 'talk' to other dynamic languages that run on top of the VM, such as Groovy and JRuby.
Since Oracle has removed the JavaFX support from NetBeans 7 we will need to use version 6.9 or older. Version 7 does not include libraries, visual editor and other features required for the creation and maintainence of JavaFx projects. Simply head on to NetBeans website and download 6.9 or 6.9.1.
