  • Mobile
    • “ SmartPhones are becoming predominant platform for consumers to interact with businesses”
    • Bilions of mobile devices running Java
      • Including SimCards
    • Running internet from a desktop is an old fashioned thing
    • Mobile devices have access to services like GPS, presence, SMS, BlueTooths
  • Sun wants to…
    • Bring JavaFX to all mobile devices
      • However: currently only some SonyEricsson and LG models (not yet available)
      • The Common Profile – mini(mal) JVM
    • Larry says he envisions Oracle Sun to produce NetBooks and mobile devices (?)
      • Along with Android (Java based) phones
    • (promote) use of Java to exploit more capabilities in mobile devices
  • Rich (Ajax, Push, Fx)
    • Enhancing User Experience
      • Attractive & interactive (Web 2.0): media, AJAX, data visualization, animation, …
      • Active User Interface : Server Push
    • RIA: Flex/Flash, Silverlight, JavaFX
    • DHTML – JQuery, Dojo, EXT-JS, …
      • Enhancing, integrated with JSF, JSP... (PHP, Python)
    • JMaki ??
  • Server Push
    • Push: server sends messages to client
    • HTTP does not allow Server to call Client
      • Server can only respond to a request
      • A bit like homing pidgeons…
    • So Client calls Server and server reponds…. when it has a message
    Browser Server Browser Browser X
  • Server Push
    • Server Push is often called ‘comet style’ or ‘ reverse Ajax’
    • The Grizzly framework provides Server Push support in Glassfish
    • Servlet 3.0 provides aysnchronous facilities that allow long-running requests to be handled
    • Atmosphere is a new project that does Grizzly for any Web container (Tomcat, Jetty, JBoss,…)
  • Demo
    • Comet Style Application using Grizzly on Glassfish
  • Java FX
    • JavaFX 1.2 released
      • Not fully upward compatible

      • Chart Components: bar, bubble, area, pie, line, 3D
      • Libraries for WebServices: REST, RSS, ATOM
    • Authoring tools for Designers: end of 2009
    • JavaFX Mobile – it is released, but not widely…
  • AJAX vs. JavaFX
  • AJAX vs. JavaFX
    • AJAX (DHTML)
    • Really fancy things very browser dependent
      • HTML 5 CANVAS tag for drawing graphics (2D APIs)
      • VIDEO tag for media support
    • JavaScript performance varies
      • Safari, Google Chrome are pretty good
    • “ Threads” – Web Workers in FF 3.1
    • Off-line: Fluid, Prism, Appcelerator
    • JavaFX
    • Immature
    • Mobile support ‘wip’
    • Multi-platform
      • runs as applet in browser
      • 2-way integrated through JS
    • Leverage Java platform
    • Rich Media support
    • Runs disconnected (off-line)
  • Integrating JavaFX and JSF
    • JavaFX runs as applet in HTML page
      • Multiple applets allowed
      • Parameters passed into JavaFX program
    • JavaScript can access JavaFX program – pass parameters and call methods
    • JavaFX program can call JavaScript functions and (beta feature) manipulate DOM directly
    • Use Case: JavaFX applets to add animation, rich visualization & media support to JSF app
  • Demo
    • Integrate JavaFX widget in JSF application
  • Product launch
    • NetBeans 6.7 (beta)
    • JavaFX 1.2

  • Interoperability
  • Interoperability
    • REST
      • http(s) + JSON/CSV/Text/XML/…
      • Simple compared to SOAP/WS*
      • Supported by JAX-RS (and Jersey)
    • Frequently used for RIA to Business or Data Service
      • For example JavaFX 1.2 has REST & RSS libraries
      • OpenSocial has REST API for server-server
    • Need for more structure than ‘WADL’
      • Describe data format
  • WS*
    • Metro seems to replace Apache AXIS as defacto standard WS* implementation
    • JAX-WS (JEE 5/J2SE 6) makes most of Java-WS interaction declarative (annotation based)
    • Little or no support for Asynchronous Services
    • Surprising J2SE 6 feature: publish a WebService on a given end-point
      • Useful for mock services for testing, receiving response from asynchronous service, …
  • Demo
    • Publish Web Service from J2SE 6 application
