Basic javafx scenebuilder fxml file causes error

Question

I am trying to create a basic window with a couple of tabs in the middle, with the first tab containing a table.

Each time I run the main java class it gives me errors, even when I get rid of table and tabs.

Here is my main file:

package application;

import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
import javafx.fxml.FXMLLoader;


public class Main extends Application {
    @Override
    public void start(Stage primaryStage) {
        try {
            BorderPane root = (BorderPane)FXMLLoader.load(getClass().getResource("Sample.fxml"));
            Scene scene = new Scene(root,400,400);
            scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
            primaryStage.setScene(scene);
            primaryStage.show();
        } catch(Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        launch(args);
    }
}

Here is my fxml file:

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

            </TabPane>
            <NavigationDrawer GridPane.columnIndex="1" GridPane.rowIndex="3" />
         </children>
      </GridPane>
   </left>
</BorderPane>

Anything helps. I couldn't find anything on this, but possible it's my fxmlloader.load file source? I really don't know.

Here is my error code:

Do you have NavigationDrawer.class in your classpath?

Caused by: java.lang.ClassNotFoundException: com.gluonhq.charm.glisten.control.NavigationDrawer

In your FXML file you have:

<?import com.gluonhq.charm.glisten.control.NavigationDrawer?>

So you need to haveNavigationDrawer.class in yourclasspath to properly load the FXML document.

If you do not you need to download it from gluonhq.

Try removing NavigationDrawer from scenebuilder / fxml and see if it works. – jpell Oct 01 '17 at 03:46
I am really confused? gluohq is scenebuilder. I have that. – StealthVice7 Oct 06 '17 at 23:55
@StealthVice7 When you build things with scenebuilder it calls the Node's constructor. Since Gluon took over scenebuilder they added some of their own nodes/classes. However you still need to have the classes on your classpath to use them. It is misleading I agree. Just like using controlsFX library you need to have it in both scenebuilder and on your classpath to use it not just one. – jpell Oct 07 '17 at 00:02
If you are using Netbeans, go to plugins and download the Gluon mobile plugin and install it. – SedJ601 Oct 07 '17 at 00:04
I'm sorry I am so confused. I already have e(fx)clipse downloaded, and scenebuilder linked to eclipse. I can open scene builder and it edits my fxml. I followed a youtube tutorial exactly. Why doesn't it work? And what exactly else do I need to do? Thanks – StealthVice7 Oct 07 '17 at 00:37
Think about it like this... TextField tf = new TextField(); You have the TextFeld class in your classpath by default with java8+. But you do not have NavigationDrawer.class in your classpath by deafult; therefore Java has no clue what a NavigationDrawer is. So when your program loads the FXML doucment it throws ClassNotFoundException. – jpell Oct 07 '17 at 00:49
So I installed gluohq mobile thing into eclipse, still doesn't work, same error it seems. Also something weird is it forced me to get rid of e(fx)clipse to install mobile. – StealthVice7 Oct 07 '17 at 01:20
download and add this .jar to your project build path "charm-glisten4.4.0.jar" http://nexus.gluonhq.com/nexus/content/repositories/releases/com/gluonhq/charm-glisten/4.4.0/ – jpell Oct 07 '17 at 01:25
Did that, added to build path. Still spits out a bunch of errors for me. – StealthVice7 Oct 07 '17 at 02:01
Just added the new error after installing gluhq mobile – StealthVice7 Oct 14 '17 at 00:46
@StealthVice7 your problem is here: Caused by: java.lang.ClassNotFoundException: application/SampleController.java...check the fx:controller in scenebuilder – jpell Oct 14 '17 at 00:49
package application; public class SampleController { } That is all my SampleController is. – StealthVice7 Oct 14 '17 at 00:55
Where do I check fx:controller in scenebuilder? – StealthVice7 Oct 14 '17 at 00:57
@StealthVice7 left side lowest titled pane or "menu list bar" under "controller" – jpell Oct 14 '17 at 00:58
It says it is : application.SampleController – StealthVice7 Oct 14 '17 at 01:04
@StealthVice7 remove ".java" from your fx:controller – jpell Oct 15 '17 at 15:38
Not sure what you mean. My fx:controller = application.SampleController. Where is ".java"? – StealthVice7 Oct 15 '17 at 22:58
@StealthVice7 not its not... in your fxml file you have "fx:controller="application/SampleController.java">" remove the .java – jpell Oct 15 '17 at 22:59
Oh damn, for some reason the one I have pasted above is .java, but I guess I was trying to fix whatever and it is application/Samplecontroller on my computer. With or without .java it still gives me errors. – StealthVice7 Oct 15 '17 at 23:14
Have you tried running my code? Does it work? Is it just a "me" thing? – StealthVice7 Oct 15 '17 at 23:14
Yeah works for me are you creating this for mobile or desktop use? – jpell Oct 15 '17 at 23:15
Desktop use. Maybe it's something that I haven't installed correctly? – StealthVice7 Oct 15 '17 at 23:17
Don't use moblie layouts for desktop application s. Does it work without the navigation drawer? – jpell Oct 15 '17 at 23:18
Is it maybe my file structure? Like where I have my files in my project folder? Also saw your newest reply, navigation drawer? – StealthVice7 Oct 15 '17 at 23:18
Oh wow. Yeah I deleted navigation drawer, and even though its awfully offcentered it doesnt give me errors anymore! what is navigation drawer? Also you said I was developing for mobile? How do I make it for desktop? – StealthVice7 Oct 15 '17 at 23:27
It was the mobile layout that you were trying to implement in your fxml file. – jpell Oct 15 '17 at 23:27
Mobile layout? How do i "un-mobile" my layout? – StealthVice7 Oct 15 '17 at 23:28
Like for a phone don't use the controls / layouts highlighted as blue in scenebuilder those are for mobile application s. – jpell Oct 15 '17 at 23:29
Thanks a lot, I didn't even know that SceneBuilder had controls and layouts specifically intended for mobile use and that that screws with the result. (although I would have thought it would still work... - also confused on what navigation drawer is - is it only for mobile too? If not wont I run into the same problem?) Thanks a lot for your help! – StealthVice7 Oct 15 '17 at 23:34
Yeah not sure what someone would use it but yes it is for moblie applications. – jpell Oct 15 '17 at 23:35
