Help needed in Hello World Application

[knights123]

Hi,

I'm a newbie to JAVAFX, i got a book JavaFX Script(Dynamic java scriptiong for Rich Internet /Client side Applications).

In that there is a first example of hello world,in which they have said and also showed the images of how the program works in javaFxPad and in IDE. Im attaching the code for the same.

I tried executing that program in javafxpad, it works fine.

I have installed Netbeans IDE 6.5.1, and if i try to execute the same HelloWorld program in that it's throwing errors and is saying the packages like javafx.ui doesnt exist.

Since im new to this field, im unable to get where im going wrong. Please help me.
