How to setup webview in javafx?

Question

@FXML
void openCaptchaSolver(MouseEvent event) {
    Stage primaryStage = (Stage)((Node)event.getSource()).getScene().getWindow();
    Stage secondaryStage = new Stage();
    WebView web = new WebView();
    WebEngine engine = web.getEngine();
    engine.load("https://www.google.com");
    VBox root = new VBox();
    root.getChildren().addAll(web);
    secondaryStage.setScene(new Scene(root, 500, 575));
    secondaryStage.setTitle("Secondary Stage");
    secondaryStage.show();
}

I'm trying to get started with WebView's in JavaFX but when trying to open one I'm receiving the errors shown below, how would I go about fixing this issue?

Caused by: java.lang.IllegalAccessError: superclass access check failed: class com.sun.javafx.sg.prism.web.NGWebView (in unnamed module @0x6b0c2d26) cannot access class com.sun.javafx.sg.prism.NGGroup (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.sg.prism to unnamed module @0x6b0c2d26

Answer 1

When getting any errors trying to run WebView make sure your VM options contain the module javafx.web.

VM Options: --module-path C:\path\to\javafx\openjfx-13.0.1_windows-x64_bin-sdk\javafx-sdk-13.0.1\lib --add-modules javafx.controls,javafx.fxml,javafx.web

In IntelliJ you can access the VM options by going to the "Edit Configurations" button in the top right of the IDE

It's late but for anyone who needs it, You just need at first add the lib to pom.xml:

<dependency> <groupId>org.openjfx</groupId><artifactId>javafx-web</artifactId> <version>17</version></dependency>

Then add: requires javafx.web to your module-info file. Build your app and you are ready to go!
