I'm trying to make an application for a college work using Maven, JavaFX, Persistence and Hibernate. I had a fully working code that used persistence, maven and hibernante with command line, and I just needed to make it work with a JavaFX interface (I couldn't find a Maven version that worked with the versions I had of Hibernate and Persistence, so I just manually added JavaFX instead of using Maven). For that, I followed a tutorial on JavaFX, and then I got myself a fully functioning but empty interface. So all I needed was to implement this interface into the Hibernate project. The problem is: Whenever I try to run my main application, I get the following error:
Exception in Application start method java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at com.sun.javafx.application.LauncherImpl.launchApplicationWithArgs(LauncherImpl.java:389) at com.sun.javafx.application.LauncherImpl.launchApplication(LauncherImpl.java:328) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at sun.launcher.LauncherHelper$FXHelper.main(LauncherHelper.java:767) Caused by: java.lang.RuntimeException: Exception in Application start method at com.sun.javafx.application.LauncherImpl.launchApplication1(LauncherImpl.java:917) at com.sun.javafx.application.LauncherImpl.lambda$launchApplication$156(LauncherImpl.java:182) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.IllegalStateException: Location is not set. at javafx.fxml.FXMLLoader.loadImpl(FXMLLoader.java:2434) at javafx.fxml.FXMLLoader.load(FXMLLoader.java:2409) at principal.Aplicacao.iniciarRootLayout(Aplicacao.java:72) at principal.Aplicacao.start(Aplicacao.java:51) at com.sun.javafx.application.LauncherImpl.lambda$launchApplication1$163(LauncherImpl.java:863) at com.sun.javafx.application.PlatformImpl.lambda$runAndWait$176(PlatformImpl.java:326) at com.sun.javafx.application.PlatformImpl.lambda$null$174(PlatformImpl.java:295) at java.security.AccessController.doPrivileged(Native Method) at com.sun.javafx.application.PlatformImpl.lambda$runLater$175(PlatformImpl.java:294) at com.sun.glass.ui.InvokeLaterDispatcher$Future.run(InvokeLaterDispatcher.java:95) at com.sun.glass.ui.win.WinApplication._runLoop(Native Method) at com.sun.glass.ui.win.WinApplication.lambda$null$149(WinApplication.java:191) ... 1 more Exception running application principal.Aplicacao
It seems like there is something work with my Start() method. The following is the code that is in the main app class (called "Aplicacao"):

this.primaryStage.setTitle("Estoque de Produtos usando Hibernate e JavaFX");

// dao = new ProdutoDAO();

}
public void iniciarRootLayout() {
try
{

controller.setMainApp(this);
} catch (IOException e) {
