Exception while runnig a javafx application jar file - exception

Question

I have a problem here with my javafx application jar, generated by Eclipse mars. Actually everything is running pretty well if I am running inside eclipse. However when I use the command line and try to run the jar of my application which was previously created by eclipse, using the command:
java -jar TalanTestingWithXPathFX.jar
I got a lot of errors in my terminal. The error are the following:
Exception in Application start method

This is some code from the main class
public class MainApp extends Application {
#FXML
private static Stage primaryStage;
#FXML
private AnchorPane rootLayout;
public Project mainProject;
public static rootLayOutController rootController;
#Override
public void start(Stage primaryStage) {
this.primaryStage = primaryStage;
this.primaryStage.setResizable(true);
this.primaryStage.setTitle("AutoGenDriver");
initRootLayout();
//showSubWindow();
}
/**
* Initializes the root layout.
*/
public void initRootLayout() {
try {
// Load root layout from fxml file.
FXMLLoader loader = new FXMLLoader();
loader.setLocation(MainApp.class.getResource("./view/rootLayOut.fxml"));
rootLayout = loader.load();
// Show the scene containing the root layout.
Scene scene = new Scene(rootLayout);
//
primaryStage.setScene(scene);
rootController=loader.getController();
// Give the controller access to the main app.
rootLayOutController controller = loader.getController();
controller.setMainApp(this);
primaryStage.show();
} catch (IOException e) {
System.out.println("Loading error");
}
}
public void setProject(Project p){
this.mainProject = p;
}
/**
* Called when the user clicks New Project.
*/
#FXML
public static Project showNewProjectDialog() {
try {
FXMLLoader loader = new FXMLLoader();
loader.setLocation(MainApp.class.getResource("view/newProjectDialog.fxml"));
AnchorPane page = loader.load();
// Create the dialog Stage.
Stage dialogStage = new Stage();
dialogStage.setTitle("Add new Test Project");
dialogStage.initModality(Modality.WINDOW_MODAL);
dialogStage.initOwner(primaryStage);
Scene scene = new Scene(page);
dialogStage.setScene(scene);
// Set the project into the controller.
newProjectDialogController controller = loader.getController();
controller.setDialogStage(dialogStage);
// controller.setProject(project);
// Show the dialog and wait until the user closes it
dialogStage.showAndWait();
return controller.getProject();
} catch (IOException e) {
System.out.println("Loading error");
return null;
}
}
public static void setPrimaryStage(Stage primaryStage) {
MainApp.primaryStage = primaryStage;
}
/**
* Returns the main stage.
* #return
*/
public static Stage getPrimaryStage() {
return primaryStage;
}
public static void main(String[] args) {
launch(args);
}
this is some code from the rootLayOutController class
public void setRootTreeView(String nameProject) {
Image image=new Image(new File("C:\\Users\\DELL 3521\\workspaceMars\\TalanTestingFX\\Images\\dossier.png").toURI().toString(),20,20,true,true);
ImageView imv= new ImageView();
imv.setImage(image);
TreeItem<String> rootNode = new TreeItem<String>(tempProject.getName(),imv);
rootNode.setExpanded(true);
testProject.add(rootNode);
t.setRoot(rootNode);
}
/**
* add sub Elements to the TreeView
*
* #param mainApp
*/
public void addItemToTreeView(String item) {
testProject.get(0).getChildren().add(new TreeItem<String>(item));
}
public static Template getTemplate() {
return template;
}
public static void setTemplate(Template template) {
rootLayOutController.template = template;
}
public AnchorPane getContent() {
return content;
}
public void setContent(AnchorPane content) {
this.content = content;
}
/**
* Initializes the controller class. This method is automatically called
* after the fxml file has been loaded.
*/
#FXML
private void initialize() {
handleTreeViewSelectElement();
newSuiteItem.setDisable(true);
openPageItem.setDisable(true);
cnxItem.setDisable(true);
openPageItem.setDisable(true);
scItem.setDisable(true);
