  • 6. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I6 Is JSF Really That Old? JavaOne 2001 technical keynote
  • 7. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I7 Restate the Scope of JSF  Separate Component Semantics from Rendering  Allow components to “own” their little patch of the UI – encode/decode  Well defined lifecycle: Inversion of Control UI Logic Substantially on Server
  • 8. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I8  Unofficial usage tracked at http://bit.ly/RealWorldJsfLinks2  or google RealWorldJsfLinks JSF Used on Every Continent Real World JSF Links

  • 10. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I10 What’s Hot Now?  HTML5 native applications – JavaScript MVC frameworks – REST  Dan North, thought leader – “The Browser is Dead…”  http://bit.ly/DanNorthBrowserIsDead PDF  http://bit.ly/DanNorthBrowserIsDeadVideo YouTube
  • 11. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I11 Dan North’s Assessment of What’s Hot Now  Technologies – Graphics: 2D and 3D + transforms – Client local storage – Sever Sent Events: Web Sockets – Ecmascript  Techniques – Everything is asynchronous – Don’t page template, just use the DOM (jQuery) – No UI state on the server
  • 12. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I12 Dan North’s Assessment of What’s Hot Now  Use standards… – W3C standards – JCP standards?  JSON JSR-353  WebSocket JSR-356  JAX-RS JSR-339
  • 13. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I13 So why are these things hot now?  Flashy results?  Maintainability?  Better runtime performance  potential for better user experience?  Wider reach?
  • 14. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I14 So why are these things hot now?  Flashy results? – This is a component library concern. Many component libraries have very flashy components. – Abstractions endure  Maintainability?  Better runtime performance  potential for better user experience?  Wider reach? JSF responses
  • 15. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I15 So why are these things hot now?  Flashy results?  Maintainability? – JavaEE/JSF was designed for large teams of corporate developers producing code that needs to stick around long after said developers have moved on. – For example, emphasis on statically typed technologies  Better runtime performance  potential for better user experience?  Wider reach? JSF responses
  • 16. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I16 So why are these things hot now?  Flashy results?  Maintainability?  Better runtime performance  potential for better user experience? – With any technology, including the HTML5 native approach, it is possible to produce a poorly performing user experience. The question is how hard is it to produce a decently performing one. – Stateless JSF is a step in that direction.  Wider reach? JSF responses
  • 17. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I17 So why are these things hot now?  Flashy results?  Maintainability?  Better runtime performance  potential for better user experience?  Wider reach? – JSF was designed for client device independence – HTML5, while growing, is still not at the least common denominator level – Being able to support IE 6 is sometimes still important JSF responses
  • 18. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I18 So why are these things hot now?  Flashy results?  Maintainability?  Better runtime performance  potential for better user experience?  Wider reach? JSF responses
  • 19. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I19
  • 20. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I20 In reality, many approaches can co-exist  JSF for one class of developers/users  HTML5 native for another  Re-use in the application tier
  • 21. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I21 Where is JSF in its Lifecycle? Implementation Status  Oracle Mojarra JSF 2.2.0 is in GlassFish 4.0, which requires JDK7  It will also run on GlassFish 3.1+, which requires JDK6  It will also run on Tomcat 7 (but you must bring your own CDI if you want to use CDI dependent features such as Faces Flows)
  • 22. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I22 My plan for your time investment  How is JSF still relevant?  Big Ticket Features: in Context – 1055 Stateless Views: Context: Performance – 1090 HTML5 Friendly Markup: Context: Markup Evolution – 730 Flows and 1142 Resource Library Contracts: Context: Multi-tenancy and Modularity  Other features: Context free
  • 23. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I23 JSF 2.2 Big Ticket Features in Context Issue numbers relative to JSF JIRA http://jsf-spec.java.net/issues/
  • 24. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I24 New to JSF?  JSF 2.0 was a blockbuster release – Facelets – Composite Components – Ajax – Resource Libraries 2.0 Big Ticket Feature Review
  • 25. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I25 1055 Stateless JSF  Kinds of state in a JSF app – UIComponent state – Model tier state – Persistence tier state What is state?
  • 26. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I26 1055 Stateless JSF  Kinds of state in a JSF app – UIComponent state – Model tier state – Persistence tier state What is state?
  • 27. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I27 1055 Stateless JSF  Kinds of state in a JSF app – UIComponent state – Model tier state – Persistence tier state  Context: Stateless is important mostly as performance concern – See http://bit.ly/LeonardoJsfPerformance Leonardo Uribe’s paper – Much can be done in the way you use JSF to reduce statefulness What is state?
  • 28. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I28 1055 Stateless JSF  Leverage existing API  Biggest gain for smallest change – Expose existing UIComponent transient property on f:view <f:view transient=“true”> – Spec changes in Restore View Phase, ResponseStateManager  Be advised – Must be on outer-most <f:view> in Facelets inclusion – View scoped managed beans will not work if the view is marked stateless JSF 2.2 approach to stateless
  • 29. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I29 1055 Stateless JSF  Automatic state management is a key value-add of JSF – Differentiates it from RESTful  Pros – Can be lazy with your UI, Why is this important?
  • 30. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I30 1090 HTML5 Friendly Markup  This is a JSF page The best part of Wicket comes to JSF
  • 31. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I31 1090 HTML5 Friendly Markup  JSF Views are written in a View Declaration Language (VDL).  The standard Facelet VDL is an XML application with two kinds of elements – HTML Markup – JSF Components  HTML Markup is passed through straight to the browser  JSF Components take some action on the server, during the lifecycle Let’s get back to basics
  • 32. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I32 1090 HTML5 Friendly Markup  Before JSF 2.2 – JSF tags hide complexity of underlying HTML+script+css+images – JSF “Renderer”:  encode: markup to browser  decode: name=value from browser <html>… <my:colorPicker value=“#{colorBean.color2}” /> <my:calendar value=“#{calendarBean.date1}” /> </html>  Context: Missing feature in browser? Write a JSF component. Let the elegance of HTML shine through
  • 33. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I33 1090 HTML5 Friendly Markup  With JSF 2.2 – Pure HTML+script+css+images in the JSF page – JSF Renderer handles decode from browser  Leverage the strength of the JSF lifecycle  Leverage the expressiveness of HTML5 <html>… <input type=“color” jsf:value=“#{colorBean.color2}”/> <input type=“date” jsf:value=“#{calendarBean.date1}” /> </html>  Context: New feature in browser? Use “pass through elements” Let the elegance of HTML shine through
  • 34. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I34 1090 HTML5 Friendly Markup  DEMO Let the elegance of HTML shine through
  • 35. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I35 1142 Resource Library Contracts 730 Faces Flows  Allow composing a JSF app as a collection of modules – Faces Flows modularize behavior – Resource Library Contracts modularize appearance  Well defined contract for each Modularity and Multi-tenant capability
  • 36. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I36 1142 Resource Library Contracts 730 Faces Flows  Two new concepts in JSF 2.2 – Resource Library Contract – Faces Flows What’s going on here? Builds on facelets concepts Builds on navigation concepts

I68 949 ClientWindow  FacesServlet now must call Lifecycle.attachWindow()  Lifecycle.attachWindow() – Takes no action unless feature is enabled – Looks for incoming client window – Creates one if not present – Stores it on the ExternalContext How does it work?
  • 69. Copyright © 2013, Oracle and/or its affiliates. All rights reserved. I69 802 File Upload Component  For the benefit of Apache Tomcat users, JSF has always chosen to lag one Servlet version behind the Java EE umbrella spec in which it is included Why so long?
