  5. 5. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I5 WE STILL NEED WEB APPS THAT ARE QUICK TO BUILD,MAINTAINABLE, LOCALIZABLE, ACCESSIBLE, SECURE, DEVICE INDEPENDENT, GOOD LOOKING, AND ARE FUN TO USE How Can JSF Still Be Relevant? Abstractions Endure
  6. 6. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I6 What About the MVC JSR? §  Facelets §  Scopes –  Flash –  View Scope Alignment between JSF and MVC M
  7. 7. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I7 § Tie up the loose ends –  Specification clarifications –  CDI alignment §  Ease of use e.g. @Inject FacesContext §  @Inject into Validators, Converters, etc. –  HtmlInputHidden is ClientBehaviorHolder § Small scale new features § Subject to Spec Lead oversight –  JSON ajax component rendering –  Stateless enhancements –  GET enhancements –  Adopt-a-JSR support JSF 2.3 in Java EE 8 Two feature drivers, each with their own agenda M
  8. 8. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I8 JSF 2.3 Small Scale New Features §  End of the line for non-CDI managed beans –  Redefine meaning of @javax.faces.bean.ManagedBean to be CDI bean –  Redefine corresponding XML syntax to be CDI bean §  Ajax method invocation –  A Faces request –  Not specific to a view –  Is specific to a ClientWindow –  Returns results in JSON §  Multi-component validation M

  10. 10. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I10 JSF 2.2 Big Ticket Features in Context Issue numbers relative to JSF JIRA http://jsf-spec.java.net/issues/
  11. 11. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I11 New to JSF? §  JSF 2.0 was a blockbuster release –  Facelets –  Composite Components –  Ajax –  Resource Libraries 2.0 Big Ticket Feature Review
  12. 12. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I12 1055 Stateless JSF §  Kinds of state in a JSF app –  UIComponent state –  Model tier state –  Persistence tier state What is state?
  13. 13. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I13 1055 Stateless JSF §  Kinds of state in a JSF app –  UIComponent state –  Model tier state –  Persistence tier state What is state?
  14. 14. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I14 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?
  15. 15. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I15 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
  16. 16. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I16 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?
  17. 17. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I17 1090 HTML5 Friendly Markup §  This is a JSF page The best part of Wicket comes to JSF <!DOCTYPE html>! <html xmlns="http://www.w3.org/1999/xhtml"! xmlns:myNS="http://xmlns.jcp.org/jsf”>! <form myNS:id="form">! <input name="textField" type="text" myNS:value="#{bean.text1}" />! <input type="submit" myNS:id="submitButton" value="submit" /> ! <p>submitted text: #{bean.text1}.</p>! </form>! </html>! !
  18. 18. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I18 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
  19. 19. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I19 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
  20. 20. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I20 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
  21. 21. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I21 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
  22. 22. Copyright © 2015, Oracle and/or its affiliates. All rights reserved. I22 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
