Load local html in JavaFX WebView

To load local html web page in WebView, we can use the code:
URL urlHello = getClass().getResource(hellohtml);
webEngine.load(urlHello.toExternalForm());



Load local html in JavaFX WebView

Create a simple local web page, hello.html.
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset=utf-8>
<title>Hello Java-Buddy!</title>
</head>
<body>
<img src="http://2.bp.blogspot.com/-Ol8pLJcc9oo/TnZY6R8YJ5I/AAAAAAAACSI/YDxcIHCZhy4/s150/duke_44x80.png"/>
<p>Hello <a href="http://java-buddy.blogspot.com/">Java-Buddy</a></p>
</body>
</html>


package javafx_webview;

import java.net.URL;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.Region;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.stage.Stage;

/**
*
* @web http://java-buddy.blogspot.com/
*/
public class JavaFX_Browser extends Application {

private Scene scene;
MyBrowser myBrowser;

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}

@Override
public void start(Stage primaryStage) {
primaryStage.setTitle("java-buddy.blogspot.com");

myBrowser = new MyBrowser();
scene = new Scene(myBrowser, 640, 480);

primaryStage.setScene(scene);
primaryStage.show();
}

class MyBrowser extends Region{

final String hellohtml = "hello.html";

WebView webView = new WebView();
WebEngine webEngine = webView.getEngine();

public MyBrowser(){

URL urlHello = getClass().getResource("hello.html");
webEngine.load(urlHello.toExternalForm());

  3. Thanks for posting this code. I find that the html file has to be located in the bin directory when using Eclipse or else the URL object is null. I am writing an application where the UI writes an html file that contains simulation model results. This file is intended to serve as a pre-written report for the model results. Is there a way to read an html file from anywhere on the machines hard drive?
