3 Unlocking the Java EE Platform with HTML 5 Overview HTML5 has suddenly become a hot item, even in the Java ecosystem. How do the 'old' technologies of HTML, JavaScript, and CSS relate to Java developers and can Java developers really be productive in this new/old world? In this session, you'll learn everything you need to know and see demos illustrating the relevance of HTML5 in the Java world, using simple and intuitive tools that have been especially created for this purpose! 3

4 Agenda What's HTML5? How to be productive with HTML5? What tools are out there? How does this relate to me as a Java developer? What tools are out there to help Java developers with HTML5? 4

5 What's HTML5? Buzz word Buzz word for rich client-side development Real pure next generation HTML JavaScript and/or CSS mashed together with HTML 5

6 What's HTML5? Web pages no longer need to look like web pages Web pages no longer need to represent single business content Web pages no longer need to be provided on a single device 6

7 What's New in HTML5? 7 New parsing rules: oriented towards flexible parsing and compatibility; not based on SGML Ability to use inline SVG and MathML in text/html New elements: article, aside, audio, bdi, canvas, command, data, datalist, details, embed, figcaption, figure, footer, header, hgroup, keygen, mark, meter, nav, output, progress, rp, rt, ruby, section, source, summary, time, track, video, wbr New types of form controls: dates and times, , url, search, number, range, tel, color[56] New attributes: charset (on meta), async (on script) Global attributes (that can be applied for every element): id, tabindex, hidden, data-* (custom data attributes) Deprecated elements will be dropped altogether: acronym, applet, basefont, big, center, dir, font, frame, frameset, isindex, noframes, strike, tt

8 What's New in HTML5? <video src="movie.webm" poster="movie.jpg" controls> This is fallback content to display if the browser does not support the video element. </video> <canvas id="example" width="200" height="200"> This text is displayed if your browser does not support HTML5 Canvas. </canvas> 8 var example = document.getelementbyid('example'); var context = example.getcontext('2d'); context.fillstyle = 'red'; context.fillrect(30, 30, 50, 50);

9 How to be Productive with HTML5? Browser-based editors Aloha Editor ( Teamlab Document Editor ( Maqetta ( Raptor Editor ( Desktop editors DreamWeaver ( Blue Griffon ( MacFlux ( Code Lobster ( 9

10 And What About CSS? And JavaScript? Stylizer ( Rapid CSS ( Style Master ( Xyle Scope ( 10 Top Style (

11 What About Integrated Tools? Edit HTML, CSS, and JavaScript in a single environment Interact easily and intuitive between different languages and files Interact with the browser click in browser and see where and how DOM nodes are defined click in elements, tags, and CSS, and see where rendered in browser 11

12 HTML5 Rich Client Development Accelerated HTML5 Development Live Web Preview and Responsive Web Design Rewritten JavaScript Editor on Nashorn JavaScript Debugger CSS3 Editor, Style Editor, and Rule Editor Backbone.js Client Generation from Existing RESTful Web Service Project 12

13 Accelerated HTML5 Development Create applications from popular templates Open existing HTML5 applications Open applications from ZIP file Use popular tutorial samples New JavaScript Library Manager 13

14 Live Preview & Responsive Design Deep integration with WebKit API Integration with embedded browser Instant feedback from page design Select in browser, see related code in IDE, and reverse without needing to save Multiple form factors, e.g., desktop or mobile, in browser 14

15 JavaScript Debugger HTML5 applications are automatically in debug mode Set breakpoints in JavaScript file, on Line, DOM, Event, or XMLHTTPRequest Refresh the browser and immediately you can step through code Use Debugger windows to monitor watches, threads, and breakpoints 15

16 CSS3 Editors Inspect and edit CSS from CSS Styles window Inspect styles applied to HTML elements in Navigator window Change in CSS Editor is immediately reflected in the browser 16

17 JavaScript Editor on Nashorn Early build of Nashorn used for parsing Syntax coloring, code completion, pattern recognition, jquery, and JSON JavaScript refactoring Many customization settings in Options window 17

18 How does this relate to me as a Java developer? Now you have choice either use Java EE or other Java-oriented frontends or HTML But how to integrate HTML frontends with Java backends? RESTful Java web services provide entry points into Java backends 18

19 Best of both worlds Java EE Platform JPA: standardized mechanism for accessing data EJB: standardized mechanism for coding business logic JAX-RS: standardized mechanism for exposing data HTML5 Platform HTML/JavaScript/CSS: front-end that connects to Java EE via JAX-RS 19

20 What tools are out there to help Java developers with HTML5? Create or open an HTML5 application Create a Backbone.js frontend from RESTful web services JavaScript file with HTML file is generated and can immediately be opened in the browser 20 In summary: You can expose a database in an HTML5 application within 5 minutes

21 Conclusion HTML5 is out there and growing in popularity Figuring out how to be productive is a key concern to success Tools exist, make sure to choose tools with the right integration HTML5 can even integrate with Java backends via RESTful web services 21
