Why can't I embed Ace Editor into WebView?

问题:

I am attempting to make a simple editor in JavaFX 2.2. I downloaded Ace Editor repository and created a test page which works fine when double clicked.

However, it does not work when I try to embed it into the WebView.

SSCCE:

package web;

import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.SceneBuilder;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.StackPaneBuilder;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.scene.web.WebViewBuilder;
import javafx.stage.Stage;

public class EditorTrial extends Application{
    WebView webView;
    WebEngine engine;
    StackPane stack;
    Scene scene;


    @Override
    public void start(Stage primStage) throws Exception {
        stack = StackPaneBuilder
                .create()
                .alignment(Pos.CENTER)
                .build();

        webView = WebViewBuilder
                .create()
                .build();

        engine = webView.getEngine();
        engine.setJavaScriptEnabled(true);
        engine.load("/home/little/Downloads/AceEditor/ace-builds-master/MyTrial.html");
        stack.getChildren().add(webView);

        scene = SceneBuilder
                .create()
                .root(stack)
                .build();

        primStage.setScene(scene);
        primStage.sizeToScene();
        primStage.show();

    }

    public static void main(String[] args) {
        Application.launch("web.EditorTrial");
    }
}  

Can someone please tell me what is wrong?

回答1:

It works for me when the absolute file path : try

File f = new File("/home/little/Downloads/AceEditor/ace-builds-master/MyTrial.html");
String StrURL = f.toURI().toURL().toString(); 
engine.load(StrURL);
