  10. 10. ExadelThe Plan Is Simple1) Ajax features in JSF 22) The new RichFaces 4
  11. 11. ExadelJavaServer 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
  12. 12. ExadelJSF 2● JSF 2 is a major upgrade over JSF 1.x● Many features, ideas taken from projects such as Seam, and RichFaces, and others
  13. 13. ExadelJSF 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
  14. 14. ExadelJSF 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
  15. 15. 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>
  16. 16. 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>
  17. 17. Exadel Attribute ValueImportant Event on which to fire the<f:ajax> event Ajax requestattributes @all @this (default) @form execute @none ids EL @all @this @form render @none (default) ids EL
  18. 18. Exadel Thats good, but where doyou get rich components and more?A rich component framework is still(?) needed to build real-world Ajax applications.
  19. 19. ExadelRichFaces 4 is a lightweight,open source framework for JSF 2
  20. 20. ExadelRichFaces 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
  21. 21. ExadelRichFaces 4 100% built on top of JSF2, just extends functionality in JSF 2
  22. 22. ExadelRichFaces 4 JavaScript is now entirelybased on the popular jQuery library
  23. 23. ExadelRichFaces 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
  24. 24. ExadelRichFaces 4 Zero-configuration.Just drop RichFaces into the application.
  25. 25. ExadelRichFaces 4 New client-side validation based on Bean Validation (JSR 303)
  26. 26. ExadelRichFaces 4 New, and easy to use CDK (Component Development Kit), allows quickly to build yourown custom rich components
  27. 27. ExadelRichFaces 4Run on: Tomcat 6/7, Resin,JBoss AS 6/7, GlassFish 3.x, WebLogic(run on any server when JSF 2 application can be deployed)
  28. 28. ExadelRichFaces 4 Run on: Google App Engine (GAE), Amazon EC2, CloudBees
  29. 29. ExadelRichFaces 4 JSF implementations: Mojarra or Myfaces
  30. 30. ExadelRichFaces 4 Any browser
  31. 31. ExadelRichFaces 4 Tooling support through JBoss Tools, IntelliJ, NetBeans
  32. 32. Exadel RichFaces versions Version JSF 1.1 JSF 1.2 JSF 2RichFaces 3.1.x •RichFaces 3.3.3* • •RichFaces 4 •* Note: RichFaces 3.3.3 has basic JSF 2 support
  33. 33. ExadelRichFaces history2005: started by Alexander Smirnov2005-2007: Developed by Exadel Ajax4jsf - open source, free RichFaces - commercial2007: JBoss takes over Exadel team continues to develop the framework, project is known as RichFaces
  34. 34. ExadelRichFaces 4 Lets look at RichFaces features in more detail...
  35. 35. ExadelRichFaces 4 core – sending an Ajax request● a4j:ajax● a4j:commandButton● a4j:commandLink● a4j:jsFunction● a4j:poll● a4j:push
  36. 36. ExadelRichFaces 4Its important to say it again, RichFaces only extends and upgrades JSF 2...
  37. 37. 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>
  38. 38. Exadel <a4j:ajax> attributesFeature/Attribute Description JavaScript to execute before Ajaxonbegin request JavaScript to execute after responseonbeforedomupdate comes back but before DOM updateoncomplete JavaScript to execute after DOM update Allows to skip JSF phases whenbypassUpdates validatinglimitRender Turns off all auto-rendered panelsstatus Status to display during Ajax requestAjax queue Advanced RichFaces client queue
  39. 39. 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}" />
  40. 40. ExadelWhen using standard JSF button:<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>When using RichFaces button:<h:form> RichFaces default <h:inputText> <h:selectOneMenu> value for <a4j:commandButton/> button/link<h:form> execute=”@form”
  41. 41. Exadel <a4j:jsFunction> – send 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>
  42. 42. 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>
  43. 43. 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)" />
  44. 44. ExadelRichFace 4 core – advancedrendering features● <a4j:outputPanel>● limitRender attribute● render=”{bean.renderList}”
  45. 45. 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
  46. 46. 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>
  47. 47. Exadel render=”#{bean.renderList}”JSF RichFaces1) Ajax request sent 1) Ajax request sent2) Component ids to be 2) Component ids to rendered resolved be rendered3) Component ids are resolved rendered into the page 3) Component ids4) 2nd Ajax request is sent. are rendered In this request the components (resolved in step 2 are sent with request) will be rendered
  48. 48. ExadelRichFace 4 core – advancedexecute features● <a4j:region>● bypassUpdates attribute
  49. 49. Exadel<a4j:region> – declarativelydefine execute region<h:form> Execute <a4j:region> options: <h:inputText /> ● @all <h:inputText /> ● @this <a4j:commandButton execute="@region"/> ● @form <a4j:region></h:form> ● @none ● ids<h:form> ● EL <a4j:region> ● @region <h:inputText /> <h:inputText /> <a4j:commandButton /> <a4j:region></h:form>
  50. 50. ExadelSkippingphaseswhenvalidating1.Restore View2.Apply Request Values3.Process Validation4.Update Model5.Invoke Application6.Render Response <h:inputText id="name" value="#{bean.name}"/> <a4j:ajax event="blur" bypassUpdates="true"/> </h:inputText> <rich:message for="name"/>
  51. 51. 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
  52. 52. ExadelJSF 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
  53. 53. ExadelRichFaces 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)
  54. 54. 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 componentare “combined” which results in just one requestfrom a component being sent. Prevents sending multiplerequest from the same component.
  55. 55. 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>
  56. 56. Exadel <a4j:queue> delay<a4j:queue requestDelay="2000"/>... Delay request by 2 seconds<a4j:commandButton value="Button1"/><a4j:commandButton value="Button2"/><a4j:queue requestDelay="2000"/>... Overwrite default<a4j:commandButton> delay request by 1 second <a4j:attachQueue requestDelay="1000"/></a4j:commmandButton><a4j:commandButton />Delay is a “wait” to combine similar events (events from thesame components) together.
  57. 57. 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>
  58. 58. ExadelRichFace 4 core – moreadvanced features● <a4j:status>● <a4j:param>● <a4j:log>● JavaScript interactions
  59. 59. 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>
  60. 60. 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="#{bean.product}" value="1009"/></a4j:commandButton>@ManagedBeanpublic class Bean { private String product; // getter and setter}
  61. 61. Exadel<a4j:log> – Ajax requestinformation● Levels: ◦ debug, info, warn, error

  75. 75. Exadel Bean Validation (JSR 303) ● JSF 2 has support for Bean Validation (server-side)public class Bean { @Pattern(regexp="...") private String email;}<h:inputText id="email" value="#{bean.email}"> <a4j:ajax event="blur"/></h:inputText><rich:message for="email"/>
  76. 76. Exadel RichFaces client validation <rich:validator>public class Bean { @Pattern(regexp="...") private String email;}<h:inputText id="email" value="#{bean.email}"> <rich:validator/></h:inputText><rich:message for="email"/>
  77. 77.
