Check in your Scenebuilder if you are referencing your Controller class. Can be edited directly in FXML this way

fx:controller="sample.Controller"

  • Sim no meu FXML tem no codigo :&#xA;&#xA;<AnchorPane id="AnchorPane" prefHeight="500.0" prefWidth="800.0" style="-fx-background-color: #010A0A;" xmlns="http://javafx.com/javafx/8.0.141" xmlns:fx="http://javafx.com/fxml/1" fx:controller="loginjavafxml.FXMLDocumentController">

  • I noticed in the error it displaying "In JDK. Package base will use system JRE.", you did the installation of your JDK? ran other projects on this machine?

  • Yes I use JDK version 1.8 I am using a JAR library also called Jfoenix https://github.com/jfoenixadmin/JFoenix including downloaded pro JDK8, yes I did other projects already but I even ran that xml standard when Voce creates a JFXML project

  • Dude I have an example of a project of mine if you want to take a look https://github.com/Phomint/Odonware, because I think it’s a problem in the Controller.

  • I will see yes! Thank you so much for helping!

  • Our you saved me was in the same controler was a beast thing

  • here : Parent root = Fxmlloader.load(getClass(). getResource("Fxmllogin.fxml"));

  • was another name so the BUG instead of Fxmllogin.fxml had something else there

  • Sure glad it worked out vlw
