Agenda What is JSF? JSF Component Model and Binding mechanism JSF Request Lifecycle IOC and Managed Beans Navigations Internalization and Resource Bundles Extending JSF Integration with Other Frameworks (Spring Framework Example) Ajax with JSF Facelets Apache MyFaces IDE Support Future of JSF Questions
4
What is JSF? a component oriented and event driven web framework to build up web applications. a Standard various implementations Sun Reference Implementation Apache MyFaces Oracle ADF IBM
5
Architecture
6
Similar Concepts Asp.net Tapestry Wicket Swing
7
JSF vs Struts Struts is an action framework Controller of the MVC pattern JSF is an event driven and component oriented framework. JSF contains all the members of the MVC. Model : Managed Beans View : Components Controller : Faces Servlet
8
JSF Component Model Covers a wide range components. Reusable Customizable State aware Easy to plug in third party components. Easy to create custom components of your own. Renderers brings abstraction
9
Simple Example: HtmlInputText Declared as; Gives the output Customization attributes like; Styleclass Javascript events (onmousover etc...)
10
Binding makes JSF powerful Value binding; binds a bean’s variable to a component. Action binding, binds a method to an action component.
11
JSF Component Tree Components are represented using a tree.
12
Event Handling Events are created based on the request parameters. Each event is broadcasted to the related listeners.
13
State Management JSF saves and restores the state of the components in each faces request. Client As a hidden variable Server As a session entry
14
JSF Request LifeCycle
15
Conversion and Validation Submitted form values are strings Conversion takes place to convert these values to java objects Validation mechanism validates these converted objects Built-in converters and validators Easy to write custom converters and validators
16
Case Study
17
IOC and Managed Beans JSF uses it’s own container to manage the beans in it’s context. pc_Index demo.Index request someVariable #{pc_DB} pc_DB demo.Db session
18
Navigations /login.jsp success /mainmenu.jsp failure /login.jsp Action specific #{loginBean.loginAction} Supports patterns *
19
Extending JSF Navigation Handler View Handler Custom Resolvers Phaselisteners Custom Components
20
Multilanguage Support for resource bundles tr en en_US de jsfsunum.messages jsfsunum/messages.tr msg_welcome = Merhaba Bundles on faces pages
21
Integration with Spring JSF-Spring Using a delegating variable resolver org.springframework.web.jsf.DelegatingVariableResolver ; backingBeanName yourpackagename.backingBeanClass request facadeService packagename.FacadeService #{facadeService}
22
Ajax with JSF Components with ajax support JSF ajax frameworks JSF Avatar Ajax Anywhere Ajax4jsf IceFaces Ajax enabled myFaces components
23
Facelets Replacing jsp markup with xhtml Templating Composite components Powerful view handler than jsf 1.1 No need for tag handlers of jsp
24
JSF IDE Support Exadel Studio IBM RSA Oracle JDeveloper Sun Studio Creator MyEclipse Bea Workshop Macromedia jsftoolbox Netbeans
25
Introducing Apache MyFaces Open source implementation of JSF Contains extended tomahawk library Oracle ADF donation
26
MyFaces Component Demo Basic form components Datatable File upload Date and Calendar Jscookmenu Schedule Accordion panel Tabbed Panel Ajax components Tree Dojo Toolkit Fisheye Html Editor Chart Creator (jsf-comp component)
27
Future JSF 1.2 and later JSF 2.0 More powerful IDE support More components Integrated Ajax Support
