Rich Internet Applications (RIA)Sri Kulkarni

Rich Internet applications (RIAs) are web applications that have most of the characteristics of desktop applicationsTypically delivered by way of standards based web browser plug-ins or independently via sandboxes or virtual machines ( Now part of browsers with HTML 5).Examples of RIA frameworks include Curl, GWT, Adobe Flash/Adobe Flex/AIR, Java/JavaFX, uniPaaS, Mozilla's XUL and Microsoft SilverlightPopular plug-in based frameworks are 1. Adbobe Flex (e.g. Mensa/VSX, Smith Barney) 2. MicroSoftSilverlight 3. JavaFXPopular plug-in based frameworks areWhat is RIA

JavaFX is a software platform for creating and delivering rich Internet applications that can run across wide variety of connected devices. The current release (JavaFX 1.2, June 2009) enables building applications for desktop, browser and mobile phones. TV set-top boxes, gaming consoles, Blu-ray players and other platforms are planned.JavaFX is fully integrated with the Java Runtime Environment (JRE) – JavaFX applications will run on any desktop and browser that runs the JRE and on top of mobile phones running Java ME.To build JavaFX apps developers use a statically typed, declarative language called JavaFX Script.On desktop, the current release supports Windows XP, Windows Vista and Mac OS operating systems. Beginning with JavaFX 1.2 Sun has released beta-releases for Linux and OpenSolaris.On mobile, JavaFX is capable of running on multiple mobile operating systems, including Symbian OS, Windows Mobile, and proprietary real-time operating systems.Sun javaFX

HTML5 is the proposed next standard for HTML 4.01, XHTML 1.0 and DOM Level 2 HTML. HTML5 is expected to be a game-changer in Web application development, making obsolete such plug-in-basedrich Internet application (RIA) technologies as Adobe Flash, Microsoft Silverlight, and Sun JavaFX.http://dev.w3.org/html5/spec/Overview.htmlHTML 5
