  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. Exadel JSF 2 is a major upgrade over JSF 1.x Many features, ideas takenfrom projects such as Seam, 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. Exadel Official RichFaces logoRichFaces 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 New client-side validation based on Bean Validation (JSR 303)
  25. 25. ExadelRichFaces 4 New, and easy to use CDK (Component Development Kit), allows quickly to build yourown custom rich components
  26. 26. 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)
  27. 27. ExadelRichFaces 4 Run on: Google App Engine (GAE), Amazon EC2, CloudBees
  28. 28. ExadelRichFaces 4 JSF implementations: Mojarra or MyFaces
  29. 29. ExadelRichFaces 4 Any browser
  30. 30. ExadelRichFaces 4 Tooling support through JBoss Tools, IntelliJ, NetBeans
  31. 31. ExadelRichFaces 4Zero-configuration, just dropRichFaces into the application
  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 – sendingan 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> –button and link with built-in Ajaxbehavior<a4j:commandButton value="Save" action="#{bean.action}" render="output" /><a4j:commandLink value="Save" action="#{bean.action}" render="output" />
  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> – fire Ajax requestfrom any JavaScript function, HTMLevent<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. ExadelIf you had to pick just one Ajaxcontrol, you would want<a4j:jsFunction><h:commandButton action="#{bean.change}"> <a4j:ajax render="id"/></h:commandButton>Is the same as: <h:commandButton onclick="sendAjax();"/> <a4j:jsFunction name="sendAjax" action="#{bean.change}" render="id"/>
  43. 43. Exadel<a4j:poll> – periodically send anAjax request<a4j:poll interval="1000" action="#{bean.count}" render="output" enabled="#{bean.pollEnabled}" /><h:panelGrid id="output">...</h:panelGrid>
  44. 44. 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)" />
  45. 45. ExadelRichFace 4 core – advancedrendering features● <a4j:outputPanel>● limitRender attribute● render=”{bean.renderList}”
  46. 46. Exadel<a4j:outputPanel> – auto renderedpanel<a4j:commandButton value="Save" action="#{bean.save}"><a4j:commandButton value="Edit" action="#{bean.edit}"><a4j:outputPanel ajaxRendered="true"> <h:panelGrid> ... </h:panelGrid></a4j:outputPanel><a4j:outputPanel ajaxRendered="true"> <rich:dataTable> ... </rich:dataTable></a4j:outputPanel>
  47. 47. ExadelTurning off auto rendered panels<a4j:commandButton value="Save" action="#{bean.save}"><a4j:commandButton value="Edit" action="#{bean.edit}" render="edit" limitRender="true"><a4j:outputPanel ajaxRendered="true"> <h:panelGrid> ... </h:panelGrid></a4j:outputPanel><h:panelGrid id="edit"> <rich:dataTable> ... </rich:dataTable></h:panelGrid>
  48. 48. Exadelrender=”#{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
  49. 49. ExadelRichFace 4 core – advancedexecute features● <a4j:region>● bypassUpdates attribute
  50. 50. Exadel<a4j:region> – defining executeregion declaratively<h:form> <a4j:region> <h:inputText /> <h:inputText /> <h:selectOneMenu /> <a4j:commandButton /> <a4j:region></h:form>
  51. 51. 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"/>
  52. 52. ExadelJavaScript callbacks during Ajaxrequest<a4j:commandLink value="Link" onbegin="ajaxOnBegin()" onbeforedomupdate="ajaxOnBeforeDomUpdate()" oncomplete="ajaxOnComplete()"></a4j:commandLink>
  53. 53. 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
  54. 54. Exadel<a4j:queue> – “combining” eventsfrom the same component While a request is executing on the server, all requests from button A or button B will be combined (merged) if the last event in the queue is of the same type.<a4j:queue />...<a4j:commandButton id="buttonA" value="Button A"/><a4j:commandButton id="buttonB" value="Button B"/>
  55. 55. Exadel<a4j:queue> – “combining” eventsfrom different components While a request is executing on the server, all requests from button A or button B will be combined (merged).<a4j:queue /><a4j:commandButton id="buttonA" value="Button A"> <a4j:attachdQueue requestGroupingId="ajaxGroup"/></a4j:commandButton><a4j:commandButton id="buttonB" value="Button B"> <a4j:attachdQueue requestGroupingId="ajaxGroup"/></a4j:commandButton>
  56. 56. Exadel<a4j:queue> – setting request delayallows “waiting” for requests fromsame component in order to mergeevents<a4j:queue requestDelay="1000"/><a4j:commandButton id="buttonA" value="Button A"> <a4j:attachdQueue requestDelay="2000"/></a4j:commandButton><a4j:commandButton id="buttonB" value="Button B"/>
  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> - like <f:param>, butsimpler as it also assigns the value toa bean property automatically<a4j:commandButton value="Save"> <a4j:param value="1009" assignTo="#{bean.product}"/></a4j:commandButton>public class Bean { private String product; public void setProduct (String product) {...}}
  61. 61. ExadelAnother great feature is that<a4j:param> value can contain anyJavaScript expression or JavaScriptfunction, when noEscape="true"<a4j:param name="width" value="(jQuery(window).width()/2)" assignTo="#{bean.screenWidth}" noEscape="true" />
  62. 62. Exadel<a4j:log> – Ajax request/responseinformation, logging
  63. 63. ExadelRichFaces UI components● Output, panels● Input● Menu● Data iteration● Tree● Drag and drop● Client side validation● Miscellaneous
