Java Fx displayed Exception in Application start method

I am a beginner of JavaFX. When I create a JavaFX project with Scene Builder. I just run and check the default user interface and got an error. The full stack trace is attached below. I don't know how to solve this problem.

Exception running application rmiClient.client.Main
I have created the javaFX application through an RMI server and client hence the file names, but according to my knowledge those files does not impact this error.

I have two theories as to why this might not work.
Maybe gson cannot set Properties. Try using a long instead of a LongProperty.
As far as I know the fields in your Java code have to have the exact same name as the fields in the json you are trying to parse. Make sure that the names match.

JavaFX - LineChart horizontal marker issue

I'm trying to add a horizontal line to a linechart in JavaFX. Found this post in SO and now trying to modify it to work in my case, however I'm getting an error, and hopefully someone can see what is the problem here.
Here is the controller code:
package gems.view;
public class GUImainController implements Initializable, Observer
{
final CategoryAxis xAxis = new CategoryAxis();
final NumberAxis yAxis = new NumberAxis();
private ArrayList<Float> tempArr = new ArrayList<>();
private ArrayList<String> tempTimeArray = new ArrayList<>();
private Series<String, Number> tempChart = new Series<>();
#FXML
private LineChartWithMarker<String, Number> lcTemperature = new LineChartWithMarker<>(xAxis,yAxis);
#Override
public void initialize(URL arg0, ResourceBundle arg1)
{
yAxis.setPrefWidth(35);
xAxis.setLabel("Temperature \\u00b0");
yAxis.setLabel("Time");
tempChart = new XYChart.Series<String, Number>();
lcTemperature.getData().add(tempChart);
tempArr.add(observable.getLatestMeasurementsFromServer().getTemperature());
tempTimeArray.add(observable.getLatestMeasurementsFromServer().getDateTime().getTime());
for (int i = 0; i < tempArr.size(); i++)
{
tempChart.getData().add(new XYChart.Data<>(tempTimeArray.get(i), tempArr.get(i)));
}
tempChart.getNode().lookup(".chart-series-line").setStyle("-fx-stroke: orange;");
String s = "test";
Data<String, Number> verticalMarker = new Data<>(s, 20);
lcTemperature.addHorizontalValueMarker(verticalMarker);
}
Here is the LineChartWithMarker class:
package gems.view;
import java.util.Objects;
import javafx.beans.InvalidationListener;
import javafx.beans.Observable;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.scene.chart.CategoryAxis;
import javafx.scene.chart.LineChart;
import javafx.scene.chart.NumberAxis;
import javafx.scene.shape.Line;
public class LineChartWithMarker<X,Y> extends LineChart
{
private ObservableList<Data<X, Y>> horizontalMarkers;
public LineChartWithMarker(CategoryAxis xAxis, NumberAxis yAxis)
{
super(xAxis, yAxis);
horizontalMarkers = FXCollections.observableArrayList(data -> new Observable[] {data.YValueProperty()});
horizontalMarkers.addListener((InvalidationListener)observable -> layoutPlotChildren());
}
public void addHorizontalValueMarker(Data<X, Y> marker)
{
Objects.requireNonNull(marker, "the marker must not be null");
if (horizontalMarkers.contains(marker)) return;
Line line = new Line();
marker.setNode(line );
getPlotChildren().add(line);
horizontalMarkers.add(marker);
}
public void removeHorizontalValueMarker(Data<X, Y> marker) {
Objects.requireNonNull(marker, "the marker must not be null");
if (marker.getNode() != null) {
getPlotChildren().remove(marker.getNode());
marker.setNode(null);
}
horizontalMarkers.remove(marker);
}
#Override
protected void layoutPlotChildren() {
super.layoutPlotChildren();
for (Data<X, Y> horizontalMarker : horizontalMarkers) {
Line line = (Line) horizontalMarker.getNode();
line.setStartX(0);
line.setEndX(getBoundsInLocal().getWidth());
line.setStartY(getYAxis().getDisplayPosition(horizontalMarker.getYValue()) + 0.5); // 0.5 for crispness
line.setEndY(line.getStartY());
line.toFront();
}
}
}
And here is the FXML (just the part for line chart):
<LineChart fx:id="lcTemperature" minWidth="100.0" prefHeight="155.0" prefWidth="708.0" BorderPane.alignment="CENTER">
<xAxis>
<CategoryAxis side="BOTTOM" />
</xAxis>
<yAxis>
<NumberAxis autoRanging="false" lowerBound="20.0" minorTickCount="10" minorTickLength="10.0" side="LEFT" tickLabelGap="10.0" tickLength="20.0" tickUnit="1.0" upperBound="30.0" />
</yAxis>
</LineChart>

Exception running application gems.view.GUIuserClient
By the way, GUIgems.fxml:42 is the last line of the FXML code I have posted above.
Also, its maybe worth mentioning that the line chart works fine if I am using a simple LineChart, like this:
#FXML
private LineChart<String, Number> lcTemperature;
It does not work when I write like this:
#FXML
private LineChartWithMarker<String, Number> lcTemperature = new LineChartWithMarker<>(xAxis,yAxis);

Alright so I managed to find a solution, if anyone will find themselves in the same situation.
Constructor of LineChartWithMarker needs to look like this:
public LineChartWithMarker(#NamedArg("xAxis") Axis<X> xAxis,
#NamedArg("yAxis") Axis<Y> yAxis)
{
super(xAxis, yAxis);
horizontalMarkers = FXCollections.observableArrayList(data -> new Observable[] {data.YValueProperty()});
horizontalMarkers.addListener((InvalidationListener)observable -> layoutPlotChildren());
}
And the FXML needs to look like this:
<?import gems.view.LineChartWithMarker?>
<LineChartWithMarker fx:id="lcTemperature" minWidth="100.0" prefHeight="155.0" prefWidth="708.0" BorderPane.alignment="CENTER">
<xAxis>
<CategoryAxis side="BOTTOM" />
</xAxis>
<yAxis>
<NumberAxis autoRanging="false" lowerBound="20.0" minorTickCount="10" minorTickLength="10.0" side="LEFT" tickLabelGap="10.0" tickLength="20.0" tickUnit="1.0" upperBound="30.0" />
</yAxis>
</LineChartWithMarker>

Spring remoting proxy injection to a spring defined FXMLController in initialization throws NoSuchBeanDefinitionException

As the title says, i have a server application which defines a RmiServiceExporter like this:
#Bean
RmiServiceExporter exporter() {
Class<Service> serviceInterface = Service.class;
RmiServiceExporter exporter = new RmiServiceExporter();
exporter.setServiceInterface(serviceInterface);
exporter.setService(service());
exporter.setServiceName("Service");//serviceInterface.getSimpleName());
exporter.setRegistryPort(1099);
return exporter;
}
and a client application, in which i have a spring configured loginScene and the RmiProxyFactoryBean.
This is the Client Spring configuration:
#Configuration
public class ClientConfig {
#Bean
public Stage primaryStage() {
return new Stage();
}
#Bean
RmiProxyFactoryBean service() {
RmiProxyFactoryBean rmiProxyFactory = new RmiProxyFactoryBean();
rmiProxyFactory.setServiceUrl("rmi://127.0.0.1:1099/Service");
rmiProxyFactory.setServiceInterface(Service.class);
return rmiProxyFactory;
}
#Bean
public Scene loginScene(){
final FXMLLoader loader = new FXMLLoader(getClass().getResource("/FXMLs/LoginFXML.fxml"));
try {
return new Scene(loader.load());
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
In the LoginController, i have an initialization method, which tries to get the service bean from the ApplicationContext, but instead NoSuchBeanDefinitionException is thrown.
Here is the LoginController:
#Data
public class LoginController {
private ApplicationContext factory;
private Service service;
#FXML private TextField textfield_username;
#FXML private PasswordField textfield_password;
#FXML
public void initialize(){
factory = new AnnotationConfigApplicationContext("Configurations.ClientConfig");
service = (Service) factory.getBean("service");
}
#FXML
private void textUsernameKeypressed(KeyEvent keyEvent) {
onEnterLogin(keyEvent);
}
#FXML
private void textPasswordKeypressed(KeyEvent keyEvent) {
onEnterLogin(keyEvent);
}
#FXML
private void buttonKeypressed(KeyEvent keyEvent) {
onEnterLogin(keyEvent);
}
private void onEnterLogin(KeyEvent keyEvent){
if (keyEvent.getCode().equals(KeyCode.ENTER))
login();
}
#FXML
private void loginButtonPressed(ActionEvent actionEvent) {
login();
}
private void login(){
try {
service.login(textfield_username.getText(), textfield_password.getText());
Alert alert = new Alert(Alert.AlertType.INFORMATION);
alert.setContentText("Login succesfull");
alert.show();
} catch (ServiceException e) {
Alert alert = new Alert(Alert.AlertType.INFORMATION);
alert.setContentText("Login failed: " + e.getMessage());
alert.show();
}
}
}

Exception running application Main
Process finished with exit code 1

I solved the problem here was the problem:
#FXML
public void initialize(){
factory = new AnnotationConfigApplicationContext("Configurations.ClientConfig");
service = (Service) factory.getBean("service");
}
it should've been:
#FXML
public void initialize(){
factory = new AnnotationConfigApplicationContext(ClientConfig.class);
service = (Service) factory.getBean("service");
}

MediaPlayer written on JavaFx doesn't work

I only rewrote the code form the video https://www.youtube.com/watch?v=bWl98dhvf8Q (to 7.51). But I use Eclipse(the guy use IntelliJ IDEA), video I have at directory /home/lynda/workspace/Lab11/ and it contains Focus.mp4 , it`s a trailer of the film(2:24).
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaView;
import javafx.scene.paint.Color;
public class Player extends Application{
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage stage) throws Exception {
Group root = new Group();
Media md = new Media("file:///home/lynda/workspace/Lab11/Focus.mp4");
MediaPlayer plr = new MediaPlayer(md);
MediaView view = new MediaView(plr);
root.getChildren().add(view);
Scene scn = new Scene(root, 400, 400, Color.BLACK);
stage.setScene(scn);
stage.show();
plr.play();
}
}
and I have many problems like this:
