            scene = new Scene(page, 700, 450);
            scene.getStylesheets().add(App.class.getResource("../skinFolder/css/defaultSkin.css").toExternalForm());

    }}

So i am trying to use the sample of the FXML Login example, only i give other way for the fxml. And in the fxml files i gave the way to the controller.

The log shows those errors:

Login Controller Class

public class LoginController {
    @FXML private TextField userId;
    @FXML private PasswordField password;
    @FXML private Label errorMessage;

    @FXML protected void processLogin() {
        if(!App.getInstance().userLogging(userId.getText(), password.getText())){
            errorMessage.setText("Username/password combination is invalid.");
        }
    }
}

And the line 28 is:

if(!App.getInstance().userLogging(userId.getText(), password.getText())){

I mention that the fxml files are in another folder the Main file folder. I don't get why i get this error when i am using the example gave by the Oracle, but with another folder structure!

My app folder structure:

  • Main
  • Model
  • Security
  • skinFolder - css
  • skinFolder - fxml
  • skinFolder - controllers

Here is the profile.fxml code:

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.control.*?>

  </styleClass>
  <properties>
    <elementLockSel>
      <Boolean fx:value="true" />
    </elementLockSel>
  </properties>
</AnchorPane>

Anyone any ideas?

I think it is related to your previous question (JavaFX 2.0 load fxml files from subfolder fails). See this answer. Same here for processUpdate action.

There is a problem in your profile.fxml file. You didn't include error description in stacktrace but most probably you have wrong or misspelled attribute tag in there.

Please, add profile.fxml and full stack trace to the post if you need more help.
