Cannot import javafx fxml class - javafx

Question

Using the FXML project template in netbeans, I've been experiencing an issue with defining the FX controller in my FXML file.
The main class, fxml document and fxml controller are all in the same package: "login".
I am importing the controller into the fxml document using it's fully qualified name.
Error occurs at the import line: "Class login.MyController does not exist."

System.out.println("do login called");
}
#FXML

System.out.println("on enter called");

package login;

MyController fxmlController = new MyController();
fxmlLoader.setController(fxmlController);
fxmlLoader.setLocation(new URL("C:/.../login/Login.fxml"));
VBox vbox = fxmlLoader.<VBox>load();
Scene scene = new Scene(vbox);
stage.setScene(scene);
stage.show();
}
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}
Note
I recently tried the following line in my FXML document:
<?import login.*?>
Which resulted in "package login does not exist."
And
<?import MyController?>
Which resulted in class does not exist.
So i'm assuming it's some kind of build path error but they're all in the same package. I even added the package that they're in to additional source packages to build from just to make sure but that didn't solve anything. My project layout is the following:
Project Name
Source Packages
login
Login.fxml
MyController.java
Main.java
I reviewed the other question postings for this problem but no one seemed to have this specific problem. If I did however miss someone's post with an identical answer, I will gladly take that reference.

Answer 1

You don't have to import it. You have to specify the full name of your controller class though.
In your case it is login.MyController so fx:controller="login.MyController".
Though you might have some other problems because I'm not having any issues when i put that import statement in the fxml. It just isn't necessary.

Answer 2

Make sure that the document you are editing is definitely the document in your package.
Somehow, in my case I was actually editing a document outside of the package with the same exact name. This is why it couldn't find the controller class when I tried to import it.
