  • 1. Rich Internet Applications (RIA)
    Sri Kulkarni
  • 2. Rich Internet applications (RIAs) are web applications that have most of the characteristics of desktop applications
    Typically 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 Silverlight
    Popular plug-in based frameworks are
    1. Adbobe Flex (e.g. Mensa/VSX, Smith Barney)
    2. MicroSoftSilverlight
    3. JavaFX
    Popular plug-in based frameworks are
    What is RIA
  • 3. Define an application interface using a set of pre-defined components (forms, buttons, and so on)
    Arrange components into a user interface design
    Use styles and themes to define the visual design
    Add dynamic behavior (one part of the application interacting with another, for example)
    Define and connect to data services as needed
    Build the source code into an SWF file that runs in the Flash Player
    Adobe Flex
  • 4. MicrosoftSilverlight is a web application framework, integrating multimedia, graphics, animations and interactivity into a single runtime environment. Initially released as a video streaming plugin, later versions brought additional interactivity features and support for .NET languages and development tools. The current version, 3.0, was released on July 9, 2009.
    It is compatible with multiple web browser products used on Microsoft Windows and Mac OS Xoperating systems. Mobile devices, starting with Windows Mobile 6 and Symbian (Series 60) phones, will likely become supported in 2010. A free software implementation named Moonlight, developed by Novell in cooperation with Microsoft, is available to bring compatible functionality to Linux, FreeBSD and other open source platforms.

  • 5. 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.

  • 6. 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.
