- 23. Zembly
- 24. Demo Show Zembly
- 25. 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
- 26. 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
- 27. 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 ??
- 28. 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
- 29. 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,…)
- 30. Demo Comet Style Application using Grizzly on Glassfish

- 32. AJAX vs. JavaFX
- 33. 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)
- 34. 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
- 35. Demo Integrate JavaFX widget in JSF application
- 36. Product launch NetBeans 6.7 (beta) JavaFX 1.2 Glassfish v3 (prelude) Later in 2009 Spring Framework 3.5 (fall?) Oracle Fusion Middleware 11g (1 st July)
- 37. Interoperability Make components work together Integrating Client technologies (Flex in HTML,…) Client to Server Across Technology Stacks From event producer to event consumer … Across vendors Multi Language JVM Scala, Groovy, JRuby, JavaScript, Java, …
- 38. Interoperability
- 39. 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
- 40. 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, …
- 41. Demo Publish Web Service from J2SE 6 application
- 42. Event Processing Complex Event Processing vs. Intelligent Event Processing (?) SQL-like syntax, visual diagramming, CQL Embedding IEP in Java Application Detecting Patterns Correlation, aggregation, exception Continuous streams of events
