Answer 1

I faced the same problem and want to share a little bit related to it. I'm using java 8 and Netbeans 8.1 and when I created a javafx FXML Application I got this one.
Here are some tips:

1. When you create new project clean and build your project before you try to run.
2. If you rename any file (controller, fxml) IDE do not apply changes to other files at least Netbeans is not doing so. So, you have to change those file names in other files manually.

3. You can define controller either in fxml file or in main class. If you want to define controller in main class use the method described by @James_D. If you want to define in fxml file than use fx:controller attribute as

    fx:controller="yourProjectName.yourFXMLDocumentControllerName"
   

   and in main class reference it as

   Parent root = FXMLLoader.load(getClass().getResource("yourFXMLFileName.fxml"));
   

4. If you think everything is correct but you still getting the error clean and build your project again and try to run.

Hope it would help someone.
