orakel FXexample

[Trjavnamen]

Ich habe aus verzweiflung ob ich etwas falsch mache das Beispiel von Orakel genommen und es in Netbeen angelegt. Mit "new FX Aplication" name: FXMLExample

Ursprünglich ohne die actionstarget1
Das Ergebnis kein Fenster im gegensatz zum ersten Exampel. Das fxml fenster mit edit geöffnet sagt kann kein fx:controller="fxmlexample.FXMLExampleController">vorhanden.
Die Umbenennung ohne Unterstrich brachte kein Ergebnis. Dann hat Netbeen die Variable
---------------------------------------------
@FXML protected void handleSubmitButtonAction(ActionEvent event) {
actiontarget.setText("Sign in button pressed");
moniert "nicht vorhanden"
nach dem Einfügen
@FXML protected void handleTusername11(ActionEvent event){
username11.getText();
hat er alles erkannt. Keine weitere Fehlermeldung. Gestartet:

[Trjavnamen]

zwar keine antwort aber im Netbeen werden in Fileeditor keine Fehler angezeigt aber der Consolen Outprint : java Results: 1 besagt Fehler. Ich habe deshalb noch die Methode wegen Nullparameter wie folgt ergenzt
public void setMain(Main main){
this.main = main;
label.setText("h");
field.setText("j");
text33.setText("h");
}
ich habe den Eintrag _JAVA_OPTION mit deM Parameter-Xmx1024m erstellt.jetzt sieht die Fehlermeldung
