I want to try out the feature of webview in my javafx project, but I kept having java.lang.reflect.InvocationTargetException, so I even tried out the sample code for WebView from jenkov.com, I still couldn't run the application. Is there anything wrong with my configurations or is it something else?
package sample;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.VBox;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
public class Main extends Application {
public static void main(String[] args) {
launch(args);
}
public void start(Stage primaryStage) {
primaryStage.setTitle("JavaFX WebView Example");
WebView webView = new WebView();
webView.getEngine().load("http://google.com");
VBox vBox = new VBox(webView);
Scene scene = new Scene(vBox, 960, 600);
primaryStage.setScene(scene);
primaryStage.show();
}
}
This is the result I got:
