Outline
JavaFX web applications
JAX-RS RESTful services
Connecting JavaFX to services

One minute JavaFX intro
Sun’s RIA platform
Competes with Flex, Flash and Silverlight
A new language
JavaFX Script
Declarative UI programming

JavaFX key features
Expressiveness
Easy component creation
Animation
Java integration
Media support
Write once, run anywhere...

Current problems
No components!
No layout managers
No selectable text
Tooling

JEE 6 ingredients
Profiles
EJB 3.0 => 3.1 (Lite)
JSF 1.2 => 2.0
JPA 1.0 => 2.0
JAX-RS => New!
WebBeans => New!

Using JEE 6
GlassFish V3
EJB3.1, JSF 2.0 and JAX-RS
No WebBeans, Servlet 3.0 and JPA 2.0 yet
Only WAR deplyment

JEE 6 & JavaFX
Browser
Desktop
JavaScript
JavaFX JavaFX HTML
HTTP
Server
JAX-RS JSF
EJB 3
JPA

2.0 highlights
JSF
Facelets
Annotation support
e.g. @ManagedBean
AJAX support
Resource loading
Project Stages

Integrating JSF & JavaFX
JSF renders to HTML
Use <applet> tag
JavaScript for communication
All text oriented functionality => JSF
All flashy stuff => JavaFX

Full page JavaFX
Too limited at this moment
Navigation, bookmarks, scrolling...
Will be an option in future versions
Ok for Swing / Desktop

JavaFX brower integration
AppletStageExtension
Browser navigation
Script evaluation
Call JavaScript methods

JavaFX calling JavaScript

Server url
JavaFX uses web services to connect to the
server
Do not hardcode the server url
Use FX.getParameter

JSF page initialization
Use @ManagedProperty to inject a request
parameter
Use @PostConstruct to initialize values

JFXtras
Layout Managers
MigLayout port
Compontents
Dialogs
Unit Testing

MigLayout example

JEE 6 & JavaFX
Browser
Desktop
JavaScript
JavaFX JavaFX HTML
HTTP
Server
JAX-RS JSF
EJB 3
JPA

JAX-RS
Expose RESTful web services
Annotation based
Easily combined with EJB and JPA
But no @EJB injection (yet)

RESTful intro
Web style web services
Resources over HTTP
Uniform Interface Connectedness
Addressability Statelessness

JAX-RS
@Path
Resource class root path
A sub-resource

JAX-RS
@GET
Method handling GET requests
@Produces
Content type supported
@PathParam
Extract value from URI template

Using JPA
Use out-of-container JPA confguration
Use EJB (Lite) Session Beans Lookup
Global JNDI namespace
@EJB
Use Session Bean as resource
Might not be in JEE 6

JEE 6 & JavaFX
Browser
Desktop
JavaScript
JavaFX JavaFX HTML
HTTP
Server
JAX-RS JSF
EJB 3
JPA

lite
EJB 3
No interface required
Runs in the web profile
No Message Driven Beans
No remote interface
No Timer service
No EJB 2.x compatibility

EJB 3.1 lite Session Bean

Global JNDI namespace
A portable namespace
java:global[/<app-name>]/<module-name>/
<bean-name>

Using Global JNDI
MobileShopServices.war

Converting
Resource Entity
Request
Converter
XML
Response
JAXB

Converting Entities
Each Entity has two converters
A single Entity converter
A list converter
A JAXB annotated wrapper class

Converter example

JavaFX web service API
JavaFX style HTTP calls
Pull style parsing
XML and JSON supported
REST only (no SOAP)

JavaFX Production Suite
Designer => Developer
Workflow

Production Suite
Workflow
Place all Replace
Photoshop elements on dummy
scene elements
Add Add action
animation handlers
