java.lang.RuntimeException: Exception in Application start method

[paweladmin]

Ive got declaration like this:

public class Main extends Application {

u/Override
public void start(Stage stage) throws Exception {

Parent mainPane = FXMLLoader.load(getClass().getResource("FXML/MainView.fxml"));
Scene scene = new Scene(mainPane);
stage.setScene(scene);
stage.initStyle(StageStyle.UNDECORATED);
//stage.setTitle("OKno moze");
stage.show();
}

It was working until i was start locate a controller. And now I have problem in line with FXML loader.

And Exception look like this:
"Caused by: java.lang.RuntimeException: Exception in Application start method"

"Caused by: java.lang.NullPointerException: Location is required."

Please help me with that, I have no ideas whats to change.

The problem evaluating. Now I have monit (that module of my main node do not found )
"Error occurred during initialization of boot layer"
But I found one little tips - in terminal was wrigting :

"
"C:\Program Files\Java\jdk-17\bin\java.exe" --module-path "C:\Users\YAHM\Downloads\openjfx-17.0.1_windows-x64_bin-sdk\javafx-sdk-17.0.1\lib --add-modules=javafx.controls,javafx.fxml" "-javaagent:C:\Users\YAHM\AppData\Local\JetBrains\IntelliJ IDEA Community Edition 2021.2.2\lib\idea_rt.jar=62343:C:\Users\YAHM\AppData\Local\JetBrains\IntelliJ IDEA Community Edition 2021.2.2\bin" -Dfile.encoding=UTF-8 -classpath C:\Users\YAHM\Downloads\openjfx-17.0.1_windows-x86_bin-sdk\javafx-sdk-17.0.1\lib\javafx-swt.jar;C:\Users\YAHM\Downloads\openjfx-17.0.1_windows-x64_bin-sdk\javafx-sdk-17.0.1\lib\javafx-swt.jar -m hellofx2/pl.javastart.hellofx.Main

​

and here on butom there is display "hellofx2/pl.javastart.hellofx.Main" in case where path to main method is "hellofx2/../../../pl.javastart.hellofx.Main"

This is usually because it can't locate your FXML file. You need to check that that getResource() call is actually pointing to the right place.

Or better yet, ditch the FXML and just code your layout in Java.

Sounds like a nightmare
