The Plan Is Simple

1) Ajax features in JSF 2

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 5

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. Sending 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>

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 is a lightweight, open source framework for

JSF 2

Exadel

RichFaces 4 – rich JSF framework

● UI components

◦ a4j:* tag library (core)

◦ rich:* tag library (UI)

◦ Components' JavaScript API

● Skins

● Client-side validation (Bean Validation based)

● CDK – Component Development Kit

Exadel

Good, now tell me what's new and what features you get in

RichFaces 4?

Exadel

RichFaces 4

100% built on top of JSF2, just extends functionality in

JSF 2

Exadel

RichFaces 4

JavaScript 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

Zero-configuration.

Just drop RichFaces into the application.

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),

Exadel

RichFaces versions

Version JSF 1.1 JSF 1.2 JSF 2

RichFaces 3.1.x •RichFaces 3.3.3* • •RichFaces 4 •* Note: RichFaces 3.3.3 has basic JSF 2 support

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

RichFaces 4

Let's look at RichFaces features in more detail...

Exadel

RichFaces 4 core – sending an Ajax request

● a4j:ajax

● a4j:commandButton

● a4j:commandLink

● a4j:jsFunction

● a4j:poll

● a4j:push

Exadel

RichFaces 4

It's important to say it again, RichFaces only extends and

upgrades JSF 2...

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”> panels. Only renders what is set in current render

status Status to display during Ajax request

<a4j:ajax> attributes

Exadel

<a4j:commandButton/Link> – Ajax button/link

/* 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" render="output" action="#{bean.action}" />

Exadel

<h:form> <h:inputText> <h:selectOneMenu> <h:commandButton> <f:ajax execute="@form"/> </h:commandButton><h:form>

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

Need to set execute=”@form”(or execute=”id1 id2”)

RichFaces defaultvalue for button/linkexecute=”@form”

Exadel

<table> ... <td onmouseover="update('yellow')"/> ...</table>

<h:form> <a4j:jsFunction name="update" action="#{bean.change}" render="..."> <a4j:param value="param1" assignTo="#{bean.color}"/> </a4j:jsFunction></h:form>

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

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 rendering features● <a4j:outputPanel>

● limitRender attribute

● render=”{bean.renderList}”

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></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

RichFace 4 core – advanced execute features● <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● @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

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

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

● Combine requests from one or more components

● Delay firing Ajax request

● 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

<a4j:queue> – “combining” events from the same component

<a4j:queue requestDelay="2000"/>…<a4j:commandButton value="Button A1"/><a4j:commandButton value="Button AB"/>

Events (clicks) from the same component are “combined” which results in just one request from a component being sent. Prevents sending multiple request from the same component.

Exadel

<a4j:queue> – “combining” events from different components

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

Exadel

<a4j:queue> delay<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

Delay is a “wait” to combine similar events (events from the same components) together.

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>

Exadel

RichFace 4 core – more advanced features● <a4j:status>

● <a4j:param>

● <a4j:log>

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

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
