3. This is a Participatory Session!
• Every now and then we will say something
interesting… and it will go out in a tweet.
• Follow @steveonjava to watch the tweets and
retweet the ones you like to your followers
• Feel free to create your own tweets using the
hash tags "#HTML5 #JavaFX #Devoxx"

4. History of the Web
1991 HTML
1994 HTML 2
1996 CSS 1 + JavaScript
1997 HTML 4
1998 CSS 2
2000 XHTML 1
2002 Tableless Web Design
2005 AJAX
2009 HTML 5
5. What is HTML5
• Web Hypertext Application Technology Working
Group (WHATWG)
• HTML5 != HTML + CSS + JavaScript
• HTML5 = Next Generation Features for Modern Web
Development
• Offline Storage, Web SQL Database, IndexedDB,
Application Cache, Web Workers, WebSocket,
Notifications, Native Drag & Drop, File System,
GeoLocation, Speech Input, Form Types, Audio,
Video, Canvas, SVG
13. Reaching Older Browsers
• Chrome Frame
– IE6, IE7, IE8 running Chrome
• Modernizr
– Feature Detection rather than User Agent Sniffing
14. Web on Mobile
• iPhone UIWebView
– Formatting Text
Indalo is an iPhone App Kevin Helped Write
15. Native Mobile Web
• Titanium
– Write JavaScript, but Renders
Native Application
– Many “Native” widgets are
UIWebView
E*Trade API Contest App Kevin Wrote
16. JavaFX 2.0 Platform
Immersive Desktop Experience Combining
the Best of JavaFX and HTML5
• Leverage your Java skills with modern
JavaFX APIs
• Integrate Java, JavaScript, and HTML5 in
the same application
• New graphics stack takes advantage of
hardware acceleration for 2D and 3D
applications
• User your favorite IDE: NetBeans, Eclipse,
IntelliJ, etc.

19. Displaying HTML in JavaFX
public class WebViewTest extends Application {
public static void main(String[] args) {
launch(WebViewTest.class, args);
}
@Override public void start(Stage stage) {
WebView webView = new WebView();
webView.getEngine().load("http://google.com");
Scene scene = new Scene(webView);
stage.setScene(scene);
stage.setTitle("Web Test");
stage.show();
}}
21. Displaying HTML in JavaFX
public class WebViewTest extends Application {
public static void main(String[] args) {
launch(WebViewTest.class, args);
}
12 Lines
@Override public void start(Stage stage) {
311 Characters
WebView webView = new WebView();
webView.getEngine().load("http://google.com");
Scene scene = new Scene(webView);
stage.setScene(scene);
stage.setTitle("Web Test");
stage.show();
}}
22. HTML in JavaFX Builders
public class WebViewTest extends Application {
public static void main(String[] args) {
launch(args);
}
11 Lines
@Override public void start(Stage stage) {
321 Characters
WebView webView = WebViewBuilder.create().build();
stage.setScene(SceneBuilder.create().root(webView).build());
webView.getEngine().load("http://google.com");
stage.setTitle("Web Test");
stage.show();
}}
23. HTML in GroovyFX
GroovyFX.start { primaryStage ->
def sg = new SceneGraphBuilder()
sg.stage(
title: 'Web Test',
show: true) { 11 Lines
scene () { 152 Characters
wv = webView()
}
}
wv.engine.load("http://google.com/")
}
24. HTML in ScalaFX
object WebViewTest extends JFXApp {
stage = new Stage {
title = "Web Test"
scene = new Scene {
WebView { 10 Lines
117 Characters
location = "http://google.com/"
}
}
}
}
25. HTML in Visage
Stage {
title: "Web Test"
Scene {
WebView {

location: "http://google.com/"
} 67 Characters
}
}
26. Calling Javascript from JavaFX
String script = "alert('We have got a message,
Houston!');”;
eng.executeScript(script);

27. Responding to Browser Events
Supported Events:
• Alert/Confirm/Prompt:
– Respond to JavaScript user interaction functions
• Resize:
– Web page moves or resizes the window object
• Status
– Web page changes the status text
• Visibility
– Hide or show the window object
• Popup
– Spawn a second web view/engine
