I have the following code structure :
enter image description here

The following is the startup code: 

public class JasonTrowbridgeC195 extends Application {

    @Override
    public void start(Stage stage) throws Exception {
        System.out.println("Start...");
        Parent root = FXMLLoader.load(getClass().getResource("src/main/java/c195/View_Controller/Login.fxml"));

        Scene scene = new Scene(root);

        stage.setScene(scene);
        stage.show();
        System.out.println("End of Start section");
    } public static void main(String[] args) throws SQLException, Exception {

    ConnectDB.makeConnection();
    launch(args);
    ConnectDB.closeConnection();

}

Getting the following exception : 
Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver has automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
Connection successful.
Start...

Exception running application c195.JasonTrowbridgeC195

I tried giving the full path to the .fxml file. Also tried using `getClass().getClassLoader().getResource` but still the same error. Not sure
what could be going wrong here.

    your resource lookup is wrong - the parameter must be a (class)path, not a file path, see [How do I determine the correct path for FXML files, CSS files, Images, and other resources needed by my JavaFX Application?](https://stackoverflow.com/questions/61531317/how-do-i-determine-the-correct-path-for-fxml-files-css-files-images-and-other) – kleopatra Sep 13 '21 at 15:59
