The Plan

● Ajax features in JSF 2

● The new RichFaces 4

Exadel

JavaServer Faces™ (JSF) is the standard component-based user interface (UI)

framework for the Java EE (5 & 6) platform

JSF 1.2 Java EE 6

JSF 2 Java EE 6

Exadel

JSF 2

● JSF 2 is a major upgrade over JSF 1.x

● Many features, ideas taken from projects such as Seam and RichFaces, and others

Exadel

● Facelets

● Composite components

● Implicit navigation

● GET support

◦ h:link, h:button

● Resource loading

JSF 2 new features

● New scopes

◦ Flash, View, custom

● Configuration via annotations

● Bean Validation support

● Basic Ajax

Exadel

JSF 2 <f:ajax>

● Very basic Ajax functionality

● Greatly inspired by RichFaces 3 <a4j:support> tag

● Ajax in JSF in 3 easy steps:

1. Firing an Ajax request

2.Partial view processing

3.Partial view rendering

Exadel

<h:form> <h:input value="#{bean.word}"/> <h:commandButton> <f:ajax event="click" execute="@form" listener="#{bean.ajaxListener}" render="out1 out2"/> </h:commandButton> <h:input value="#{bean.text}" id="out1"/> <h:input value="#{bean.phrase}" id="out2"/></h:form>

render

@all@this@form@none (default)Id's EL

Important <f:ajax> attributes

Exadel

That's good, but where do you get rich components and

more?

A rich component framework is still(?) needed to build

real-world Ajax applications.

Exadel

RichFaces 4 – rich JSF framework

● JSF 2 based

● Components

◦ a4j:* tag library (core)

◦ rich:* tag library (UI)

● Skins

● Client-side validation (Bean Validation/JSR 303 based)

● CDK – Component Development Kit

Exadel

Exadel

Deploy on any server which supports JSF 2

Any browser

Exadel

RichFaces history

2005: started by Alexander Smirnov

2005-2007: Developed by Exadel Ajax4jsf - open source, free RichFaces - commercial

2007: JBoss takes over

Exadel team continues to develop the framework, project is known as RichFaces

Exadel

Just tell me when RichFaces 4 is going to be released?

Exadel

Good, now tell me what's really new and improved in

RichFaces 4?

Exadel

RichFaces 4

JavaScript in RichFaces is now entirely based on the

popular jQuery library.

Exadel

RichFaces 4

● All components are reviewed for consistency, usability

● Redesigned following semantic HTML principles

● Server-side and client-side performance optimization

● Strict code clean-up and review

Exadel

RichFaces 4

● New client-side validation based on Bean Validation (JSR 303)

Exadel

RichFaces 4

● New and easy to use CDK (Component Development Kit)

● Quickly build your own custom rich components

Exadel

Cloud deployment

● Google App Engine (GAE)

● Amazon EC2

● Special Maven-based plug-in available

Exadel

RichFaces <a4j:ajax>

● 100% based on standard <f:ajax>

● Just replace f: with a4j: and get exactly the same functionality

● But, you get extra features...<h:commandButton> <f:ajax execute="@form" render="output"/></h:commandButton>

<h:commandButton> <a4j:ajax execute="@form" render="output"/></h:commandButton>

Exadel

Attribute Description

onbegin JavaScript to execute before Ajax request

onbeforedomupdateJavaScript to execute after response comes back but before DOM update

oncomplete JavaScript to execute after DOM update

bypassUpdatesSkips Update Model and Invoke Application phases, useful for form validation

limitRenderSkips all a4j:outputPanel ajaxRender=”true” areas. Only renders what is set in current render

status Status to display during Ajax request

<a4j:ajax> attributes

Exadel

That's not all, there are more RichFaces goodies...

Exadel

RichFaces 4 core – firing an Ajax request

● a4j:ajax

● a4j:commandButton

● a4j:commandLink

● a4j:jsFunction

● a4j:poll

● a4j:push

Exadel

<a4j:commandButton> – Ajax button

/* standard button with f:ajax */<h:commandButton value="Save" action="#{bean.action}"> <f:ajax execute="@form" render="output"/></h:commandButton>

/* RichFaces button */<a4j:commandButton value="Save" execute="@form" render="output" action="#{bean.action}" />

Exadel

<table> ... <td onmouseover="update('yellow')"/> ...</table><h:form> <a4j:jsFunction name="update" action="#{bean.change}" reRender="panel"> <a4j:param value="param1" assignTo="#{bean.color}"/> </a4j:jsFunction><h:form>

<a4j:jsFunction> – fire Ajax request from any JavaScript function

Exadel

<a4j:poll> – periodically send an Ajax request

<a4j:poll interval="1000" action="#{bean.count}"

render="output" enabled="#{bean.pollEnabled}" />

<h:panelGrid id="output">...</h:panelGrid>

Exadel

<a4j:push>

● Server-side events are pushed to client using Comet or WebSockets.

● Implemented using Atmosphere

● Provides excellent integration with EE containers, and advanced messaging services

<a4j:push address="topic@chat" ondataavailable="alert(event.rf.data)" />

Exadel

RichFace 4 core – advanced features and rendering● a4j:outputPanel

● limitRender attribute

● render=”{bean.renderList}”

● a4j:param

Exadel

<a4j:outputPanel> – auto rendered panel

<h:selectOneMenu value="#{bean.fruit}"> <a4j:ajax listener="#{bean.change}"/></<h:selectOneMenu><a4j:outputPanel ajaxRendered="true"> <h:panelGrid> ... </h:panelGrid> <h:panelGrid> ... </h:panelGrid></a4j:outputPanel>

Rendered on every Ajax request

Exadel

Advanced rendering options: limitRender

<a4j:commandButton render="output"/><a4j:commandButton render="output" limitRender="true"/>

<h:panelGrid id="output">...</h:panelGrid>

<a4j:outputPanel ajaxRendered="true">...</a4j:outputPanel>

Turns off all auto rendered panels,only renders what is set in currentrender

Exadel

render=”#{bean.renderList}”

1) Ajax request sent

2) Component id's to be rendered resolved

3) Component id's are rendered into the page

4) 2nd Ajax request is sent. In this request the components (resolved in step 2 are sent with request) will be rendered

1) Ajax request sent

2) Component id's to be rendered resolved

3) Component id's are rendered

JSF RichFaces

Exadel

<a4j:param>

● Similar to <f:param> but simpler as it also assigns the value to a bean property automatically

<a4j:commandButton value="Save"> <a4j:param name="product" value="1009"/></a4j:commandButton>

public class Bean { private String product; public void setProduct (String product) {...} public String getProduct () {...}}

Exadel

RichFace 4 core – advanced processing● a4j:region

● bypassUpdates attribute

Exadel

<a4j:region> – declaratively define execute region<h:form> <a4j:region> <h:inputText /> <h:inputText /> <a4j:commandButton execute="@region"/> <a4j:region></h:form>

<h:form> <a4j:region> <h:inputText /> <h:inputText /> <a4j:commandButton /> <a4j:region></h:form>

Execute options: ● @all● @this (default)● @form● @none● Id's● EL● @region

Exadel

Skipping phases when validating

<h:inputText id="name" value="#{bean.name}"/> <a4j:ajax event="blur" bypassUpdates="true"/></h:inputText><rich:message for="name"/>

1.Restore View2.Apply Request Values3.Process Validation4.Update Model5.Invoke Application6.Render Response

Exadel

RichFace 4 core – other advanced features● a4j:status

● a4j:log

● a4j:queue

● JavaScript interactions

Exadel

<a4j:status> – Ajax request status

<a4j:status name="ajaxStatus"> <f:facet name="start"> <h:graphicImage value="ajaxStatus.jpg"/> </f:facet></a4j:status>

<h:form> <inputText /> <inputText /> <a4j:commandButton status="ajaxStatus"/></h:form>

Exadel

<a4j:log> – Ajax request information● Levels:

◦ debug, info, warn, error

Exadel

JSF 2 queue

● JSF 2 has very basic queue functionality

● Events are queued and fired one at a time

● Only one request is processed on the server at a time

Exadel

RichFaces queue upgrades

● Delay firing of a request

● Combine requests from one or more controls

● Cancel DOM updates if “similar” request was fired

● Define queue as:

◦ Global (all views have queue)

◦ View-based

◦ Form-based

◦ Named (used by particular components only)

Exadel

RichFaces <a4j:queue>

<a4j:queue requestDelay="2000"/>...<a4j:commandButton value="Button1"/><a4j:commandButton value="Button2"/>

<a4j:queue requestDelay="2000"/>...<a4j:commandButton> <a4j:attachQueue requestDelay="1000"/></a4j:commmandButton><a4j:commandButton />

Delay request by 2 seconds

Overwrite default delay request by 1 second

Exadel

a4j:queue – “combining” events

<a4j:queue requestDelay="2000"/>...<a4j:commandButton> <a4j:attachQueue requestGroupingId="mainGroup"/></a4j:commmandButton><a4j:commandButton> <a4j:attachQueue requestGroupingId="mainGroup"/></a4j:commmandButton>

Exadel

a4j:queue – ignoring “stale” responses

<a4j:queue requestDelay="2000 ingoreDupResponses="true"/>

<h:inputText value="#{bean.state}"> <a4j:ajax event="keyup" listener="#{bean.load}" render="states"/></h:inputText>

<rich:dataTable id="states"> <rich:column/></rich:dataTable>

Exadel

JavaScript interactions

<a4j:commandLink value="Link" onbegin="ajaxOnBegin()" onbeforedomupdate="ajaxOnBeforeDomUpdate()" oncomplete="ajaxOnComplete()"></a4j:commandLink>

<h:commandLink value="Link" <f:ajax onevent="ajaxEvent();"></h:commandLink>

Called three times:1) begin2) success3) complete

Events are separated for easier development
