Traditional Web applicationClientServerFigure 1: Traditional Web Application ArchitectureTraditional web applications have some limitations. In traditional web applications, data resides on the server. So offlineusage is not possible. Plus all validation and preparation of data onserver side. In traditional web applications, there is only one controller at theserver side, which handles the page. At each user interaction, thewhole page is computed by scratch and reloaded. Partial pagerefreshment also not possible.JavaFX 1
Overview of Rich Internet Applications(RIAs)A new kind of web applications came up to overcome these limitations:Rich Internet Applications (RIAs)RIAs are web applications.The Word "rich" is used to take attention towards the difference to theearlier generation of web applications.RIA delivers the same features and functions as of desktop applications. Atthe client side, RIAs give a similar look-and-feel as desktop applications. Generally, RIA will divide processing across Internet/network.User Interface and related activities and capability will be done at client sideand processing related to data manipulation operation will be done atserver side.However this is general scenario! A developer can decide his own workdistribution way.As client is also managing data and process both, network traffic will bereduced. The client will not need to request to server for each and everysmall data preparation.So offline usage of application is also possible. Traditional web applications has only one controller at theServer side, that handles the page. When a client sends request handler willhandle it. And page will be reloaded after response.RIA can have a second controller at client side.That can handle computation and refreshment of a portion of a page. Solive validation, offline usage and page rearrangements are possible.2JavaFX
In Traditional web app, On user request, browser sends HTTPrequest to server. Page is refreshed when response comes back. So clienthas to wait for response on each and every request. This is synchronouscommunication. Which creates negative impact on usability.While, RIAs use both synchronous and asynchronous communications.So partial page refreshment, page rearrangement, display morphing arepossibleJavaFX 3
Introduction to JavaFXJavafx is a set of graphics and media packages for developers to create RIA.Project development life cycle includes design, create, test, debug, anddeploy phases of project.Developer can use JavaFX for all these phases.JavaFX is created by oracle. Java FX for ARM processors is in developer preview phase.On desktops, the JavaFX supports Windows XP, Windows Vista,Windows 7, Windows 8, Mac OS X and Linux operating systems. InJavaFX 1.2, Oracle has released beta versions for OpenSolaris.JavaFX Mobile 1.x is capable of running on multiple mobileoperating systems, including Symbian OS, Windows Mobile, andproprietary real-time operating systems. If a desktop can run JavaSE, it can run JavaFX Application.If a mobile phone can run JavaME, it can run JavaFX Application.If a browser can run JavaEE, it can run JavaFX Application. JavaFX script was used before version 2.0.It is statically typeddeclarative language. That is directly compiled to Java byte code. JavaFX2.0 and later are Java library that consists of classes andinterfaces that are written in native Java code. Developers can integrate advance graphics into JavaFx applicationusing plug ins of Adobe Photoshop and Illustrator. Developers canthen add animation or effects to the static graphics imported. For end user it’s "Drag-to-Install”. If any application running insidebrowser, end user can drag the application & can drop it to desktop.The application will be in same state and context even after browseris closed. SVG graphics converter tool is there to import graphics andpreviewing assets after the conversion to JavaFX format A designer can use scene builder to design GUI. Or he can useFXML to code.It is XML based declarative markup language.Scene Builder will generate FXML markup automatically .which canbe ported to an IDE.4JavaFX
To embed a web page within JavaFX application, Web View isthere.it uses WebKitHTML technology.Any JavaScript that is running in WebView,it can call Java APIs, andJava APIs can call JavaScript running in WebView. Existing Swing applications can be updated with new JavaFX features. To develop a full featured application, so many controls are there.And to design a designer can use CSS. JavaFX provides support for multitouch operations. If there is supported graphics card or graphics processing unit(GPU),JavaFX offers smooth graphics. If system doesn’t featureGPUs supported by Javafx,then it wil default to java2D softwarestack. Deployment is easy with Self-contained application packages. It willhave all of the application resources and a private copy of the Javaand JavaFX runtimes.Table 1 : History of JavaFXRelease DateDecember 4, 2008February 12, 2009June 2, 2009April 22, 2010October 10, 2011April 27, 2012August 14, 2012March s And MacOSWindows And MacOSWindows ,MacOS,Linux,SolarisWindows ,MacOS,Linux,SolarisWindowsWindows ,MacOSWindows ,MacOS,LinuxWindows ,MacOS,LinuxJavaFX 5
Exploring JavaFX APIIf you want a separation of code and design, you have FXML to design theinterface and a Java program called a controller to handle to logic.If you want style you now have a markup language that is amazingly similarto CSS that can be used to customized the look and feel of your application.If you want to render 2d or 3d graphics or animate things, JavaFx has acanvas very similar to the HTML canvas and a whole subset of classesdesigned to handle animation.All in 1 download, all in 1 technology. !6JavaFX
Understanding JavaFX Scene GraphEach visual element is called node here. Each position in the scene graphtree known as a node.Scene graph is hierarchical tree of nodes. It can be thought of as a familytree of visual elements (e.g., UI controls, 2D shapes, images, video playerscharts etc.)A node will be in particular state. Like position or orientation.A node can have effect like blurs, shadows, and color adjustment etc.As in your family, your father is above you, and child below you.The same way visual elements father would be above it child below it.The root node(the top node) is the only node within the scene graphwithout a parent node. Branch Nodes – Which have parent class and child class both. Forexample, Group objects (a collection of nodes), Region objects(i.e., StackPane, FlowPane) can have child nodes. But it alsoJavaFX 7
includes Control objects (e.g., Button, ChoiceBox) which can'thave child nodes. Leaf Nodes - These nodes cannot have child nodes. For example,Shape objects (e.g, Circle, Rectangle), ImageView objects (fordisplaying images) and MediaView objects (used for playing musicor video).8JavaFX
Comparing JavaFX with SwingOracle states:“JavaFX is replacing Swing as the new client UI library for Java SE.However, Swing will remain part of the Java SE specification for theforeseeable future, and therefore included in the JRE. While werecommend developers to leverage JavaFX APIs as much as possible whenbuilding new applications, it is possible to extend a Swing application withJavaFX, allowing for a smoother transition.”JavaFX 9

This tutorial is a compilation of three documents that were previously delivered with the JavaFX 2.x documentation set: JavaFX Overview, JavaFX Architecture, and Getting Started with JavaFX.
This chapter describes how to add JavaFX co ntent into a Swing application and how to use threads correctly when both Swing and JavaFX content operate within a single application. JavaFX SDK provides the JFXPanel class, which is located in the javafx.embed.swing package and enables you to embed
Oct 10, 2011 · Support for ARM platforms has also been made available with JavaFX 8. JDK for ARM includes the base, graphics and controls components of JavaFX. To install JavaFX install your chosen version of the Java Runtime environment and Java Development kit. Features offered by JavaFX include
Database Operations in JavaFX . At first, part of JavaFX tutorial series, we created a sample JavaFX project, designed the draft version of the UI and set up an Oracle XE database. In this post, we will create controller, model, DAO, and Util classes to do DB operations. Before starting to code, I want to give more information about our example .
