3 JavaONE 2010 | sun.com/javaone Why JavaFX? > & specifically for mobile development

4 JavaONE 2010 | sun.com/javaone Why NetBeans & GlassFish?

5 JavaONE 2010 | sun.com/javaone Exercise 0 - IDE setup plus ReST test > Goal – Check NetBeans installed & check external ReST service (Amazon Cloud)

6 JavaONE 2010 | sun.com/javaone Exercise 1 – JavaFX Simple UI > Goal – First JavaFX project and JavaFX project using “states”

7 JavaONE 2010 | sun.com/javaone Housekeeping > Before you leave, please fill out a survey and hand it to someone We really want to know what you think! > Please log out of your machine when done > Please look around to make sure you have all of your belongings > The hard copies of the lab guides are yours to keep

11 JavaONE 2010 | sun.com/javaone JavaFX Mobile packaging

12 JavaONE 2010 | sun.com/javaone JavaFX in a nutshell > Scripting, declarative, object oriented language & API for Graphical Applications Cool Language w/ data binding and triggers Rich Graphics API Multimedia ready > Tools for developers and designers JavaFX SDK NetBeans Samples Adobe Illustrator & Photoshop plugins > Built on top of Java™ platform

13 JavaONE 2010 | sun.com/javaone REST Architecture > REST Architecture Principles Representational State Transfer Everything is a resource Resources are addressable Resources have an interface (operations and data types) Protocol is client-server, stateless, cacheable, layered

14 JavaONE 2010 | sun.com/javaone RESTful Web Services > JSR 311, aka aka JAX-RS Part of Java EE 6 specification > RESTful web service is A Java class A set of methods > Use Java annotations to represent The resources (the URI) The Operations The Data Types (as MIME types) > Jersey is JAX-RS Reference Implementation

15 JavaONE 2010 | sun.com/javaone JSON, JavaScript Object Notation > A data format to exchange data structures > Language independent > Mainly used for object serialization and AJAX { "firstName": "John", "lastName": "Smith", "address": { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": }, "phoneNumbers": [ " ", " " ] }

16 JavaONE 2010 | sun.com/javaone Exercises > Exercise 1: Create a Simple JavaFX Application ● Expected duration: 20 minutes > Exercise 2: Create the JavaFX UI ● Expected duration: 30 minutes > Exercise 3: Add Photos with JavaFX ● Expected duration: 30 minutes > Exercise 4:... ● Expected duration: 20 minutes > Lab built on JavaFX 1.3

18 JavaONE 2010 | sun.com/javaone Getting Started > If you have not logged in, log in with username: x password: y > Online lab guide will open in a browser window > All necessary software and lab files are already installed on your lab machine Start from exercise 1

19 JavaONE 2010 | sun.com/javaone Exercise 1 > Create your first JavaFX application Create the project Build, Run and Test > Add a Label > Modify the backgroundwall paper, using the CSS

20 JavaONE 2010 | sun.com/javaone Exercise 1... > Change the UI theme Change the back groundwall paper Background fill: select linearGradient Change the Component style using Stylesheets: apply your style sheet: {__DIR__}javafx.css

22 JavaONE 2010 | sun.com/javaone Exercise 2 > Create a Web Application Create, Build, Run and Test > Add a RESTful web service Will return text/plain data type Build, Run and Test > Add a method that will return JSON data Will return application/json data type Build, Run and Test

23 JavaONE 2010 | sun.com/javaone Exercise 3 > Return to the JavaFX Application > Add an asynchronous call to the RESTful web service > Use Java based JSON parser to parse the result var request : RemoteTextDocument = RemoteTextDocument { url: " } var value: String = bind request.document on replace { if (request.done) { //do something with value }

24 JavaONE 2010 | sun.com/javaone Exercise 4 > Add polling capabilities to JavaFX Reuse existing java.util.Timer class Poll every 5000 ms class PieChartTask extends TimerTask { override function run() { //wrap existing connection and parsing code } }; def timer : Timer = new Timer("TimerThread"); def task : PieChartTask = new PieChartTask(); timer.schedule(task, 0, 5000);
