Question

我的问题是我的javafx应用程序jar，由Eclipse mars生成。实际上，如果我在eclipse中运行，一切都运行良好。但是，当我使用命令行并尝试运行以前由eclipse创建的应用程序的jar时，使用以下命令：

java -jar TalanTestingWithXPathFX.jar

我的终端出了很多错误。错误如下：

Exception running application talan.test.webApp.MainApp

Answer 1

这是主类的一些代码

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);
}

这是来自rootLayOutController类的一些代码

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);
    acItem.setDisable(true);
    dactItem.setDisable(true);

}
