How to open local text file with JavaFX WebView

Is that possible to open local text file with JavaFX WebView ? I have tried the following code but it was not working. How can I enable this?

WebView wv = new WebView();
wv.getEngine().setCreatePopupHandler(new Callback<PopupFeatures, WebEngine>() {

    @Override
    public WebEngine call(PopupFeatures p) {
        Stage stage = new Stage(StageStyle.UTILITY);
        WebView wv2 = new WebView();
        stage.setScene(new Scene(wv2));
        stage.show();
        return wv2.getEngine();
    }
});

wv.getEngine().loadContent("<a href="file:///C:\Users\Dev\infor.txt">Open File</a>");

StackPane root = new StackPane();
root.getChildren().add(wv);

Scene scene = new Scene(root, 300, 250);

primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();

Yes, you can open a local text file with a JavaFX WebView.

Sample app:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.web.WebView;
import javafx.stage.Stage;

public class WebViewWithLocalText extends Application {

    @Override
    public void start(Stage stage) throws MalformedURLException {
        String location =
                new File(
                        System.getProperty("user.dir") + File.separator + "test.txt"
                ).toURI().toURL().toExternalForm();

        System.out.println(location);

        WebView webView = new WebView();
        webView.getEngine().load(location);

        // use loadContent instead of load if you want a link to a file.
        // webView.getEngine().loadContent(
        //     "<a href=\"" + location + "\">Open File</a>"
        // );

        Scene scene = new Scene(webView);
        stage.setScene(scene);
        stage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

Place a text file at the location reported by System.out when you run the program.

Sample output:

Some errors in your supplied code:

  1. You don't escape quotes.
  2. You don't supply a valid file URI, you supply windows path prefixed by a file protocol.
  3. You hardcode a path and drive specifier, which is likely not a portable solution between systems.

I don't have a windows machine to test, but perhaps something like this would work for your absolute path.

wv.getEngine().loadContent("<a href=\"file:///C:/Users/Dev/infor.txt\">Open File</a>");
