Current problems

No components!No layout managersNo selectable textTooling

JEE 6 ingredients

Using JEE 6

GlassFish V3EJB3.1, JSF 2.0 and JAX-RSNo WebBeans, Servlet 3.0 and JPA 2.0 yetOnly WAR deplyment

JavaFX

FaceletsAnnotation support

e.g. @ManagedBeanAJAX supportResource loadingProject Stages

2.0 highlightsJSF

Integrating JSF & JavaFX

JSF renders to HTMLUse <applet> tagJavaScript for communication

All text oriented functionality => JSFAll flashy stuff => JavaFX

Full page JavaFX

Too limited at this momentNavigation, bookmarks, scrolling...

Will be an option in future versionsOk for Swing / Desktop

JavaFX brower integration

AppletStageExtension Browser navigationScript evaluation

Call JavaScript methods

JavaFX calling JavaScript

Server url

JavaFX uses web services to connect to the serverDo not hardcode the server urlUse FX.getParameter

JSF page initialization

Use @ManagedProperty to inject a request parameter

Use @PostConstruct to initialize values

But no @EJB injection (yet)

JAX-RS

RESTful intro

Web style web servicesResources over HTTP

Uniform Interface

Addressability

Connectedness

Statelessness

@PathResource class root pathA sub-resource

JAX-RS

@GETMethod handling GET requests

@ProducesContent type supported

@PathParamExtract value from URI template

JAX-RS

Using JPA

Use out-of-container JPA confgurationUse EJB (Lite) Session Beans Lookup

Global JNDI namespace@EJB

Use Session Bean as resourceMight not be in JEE 6

Global JNDI namespace

A portable namespace

java:global[/<app-name>]/<module-name>/<bean-name>
