I just installed NetBeans 7.1.2, and JDK 7U4 and JavaFX2.1 Runtime, JavaFX2.1 SDK., then I used NetBeans to create a new JavaFx project with the default code, ans it ran fine to give "Hello World" on the console. Good... Then I used NetBeans to create a new JavaFX/FXML project with the default code -- Sample.java, Sample.fxml, and the main program, but then I got problem when I ran it. Please can someone tell me what gent wrong with my case. The following is the output on the console :
