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

JSF 2 new features
● Facelets ● New scopes
● Composite ◦ Flash, View,
components custom
● Implicit ● Configuration

navigation via annotations
● GET ● Bean Validation
support
support
◦ h:link, h:button
● Basic Ajax
● Resource loading

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" 1
execute="@form" 2
listener="#{bean.ajaxListener}"
render="out1 out2"/> 3
</h:commandButton>
<h:input value="#{bean.text}" id="out1"/>
<h:input value="#{bean.phrase}" id="out2"/>
</h:form>

Exadel

<h:form>
<h:input value="#{bean.word}"/>
<h:selectOneMenu value="#{bean.selected}">
<f:selectItems value="#{bean.items}"/>
<f:ajax event="change" 1
execute="@form" 2
listener="#{bean.ajaxListener}"
render="@form"/> 3
</h:commandButton>
<h:input value="#{bean.text}" id="out1"/>
<h:input value="#{bean.phrase}" id="out2"/>
</h:form>

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)

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

<a4j:ajax> attributes
Attribute Description

onbegin JavaScript to execute before Ajax request
JavaScript to execute after response
onbeforedomupdate
comes back but before DOM update
oncomplete JavaScript to execute after DOM update
Skips Update Model and Invoke
bypassUpdates Application phases, useful for form
validation
Skips all <a4j:outputPanel
limitRender ajaxRender=”true”> panels. Only
renders what is set in current render
status Status to display during Ajax request

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>
Need to set
<h:commandButton> execute=”@form”
<f:ajax execute="@form"/> (or execute=”id1 id2”)
</h:commandButton>
<h:form>

<h:form> RichFaces default
<h:inputText>
<h:selectOneMenu>
value for
<a4j:commandButton/> button/link
<h:form> execute=”@form”

Exadel

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

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
● Providesexcellent 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> Rendered on every
</a4j:outputPanel> Ajax request

Exadel

Advanced rendering options:
limitRender

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

<h:panelGrid id="output">
Turns off all auto rendered panels,
...
only renders what is set in current
</h:panelGrid> render

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

Exadel

render=”#{bean.renderList}”
JSF RichFaces
1) Ajax request sent 1) Ajax request sent
2) Component id's to be 2) Component id's to
rendered resolved be rendered
3) Component id's are resolved
rendered into the page 3) Component id's
4) 2nd Ajax request is sent. are rendered
In this request the
components (resolved in
step 2 are sent with
request) will be rendered

Exadel

RichFace 4 core – advanced
execute features
● <a4j:region>
● bypassUpdates attribute

Exadel

<a4j:region> – declaratively
define execute region
<h:form> Execute
<a4j:region> options:
<h:inputText /> ● @all
<h:inputText />
● @this
<a4j:commandButton execute="@region"/>
● @form
<a4j:region>
</h:form> ● @none

● id's
<h:form> ● EL
<a4j:region>
● @region
<h:inputText />
<h:inputText />
<a4j:commandButton />
<a4j:region>
</h:form>

Exadel

Skipping
phases
when
validating
1.Restore View
2.Apply Request Values
3.Process Validation
4.Update Model
5.Invoke Application
6.Render Response

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

Exadel

JavaScript interactions
<h:commandLink value="Link"
<f:ajax onevent="ajaxEvent();">
</h:commandLink>
Called three times:
1) begin
2) success
3) complete

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

Events are separated for easier development

Exadel

JSF 2 queue
● JSF2 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:commandButton>
<a4j:attachQueue requestGroupingId="ajaxGroup"/>
</a4j:commmandButton>
<a4j:commandButton>
<a4j:attachQueue requestGroupingId="ajaxGroup"/>

Exadel

<a4j:queue> delay
... Delay request
by 2 seconds
<a4j:commandButton value="Button1"/>
<a4j:commandButton value="Button2"/>

... Overwrite default
<a4j:commandButton> delay request
by 1 second
<a4j:attachQueue requestDelay="1000"/>
<a4j:commandButton />

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 () {...}
}
