ĐỀ TÀI : JSF and Ajax with Project Woodstock

Tác giả : Doris Chen Ph.D.
ã Value and Method Binding
ã Managed Beans
ã Navigation, Request Processing Lifecycle



Background
ã Building AJAX based applications could be easier?
ã Classic computer science answer: encapsulation
- Hide functionality behind simple building blocks
- Provide a framework for assembling complicated things out of
simple things
- Embed the encapsulations inside development tools that can
do some of the grunt work
ã In this talk, we will examine using JavaServer Faces to
encapsulate AJAX technologies
- But first, we need to understand what JavaServer Faces (JSF)
is all about .

User Interface Components
ã Contains the current state of a component:
- Visual appearance characteristics
- Bindings to model tier data and event handlers
ã Implemented as a classic JavaBean:
- Properties – state characteristics
- Methods – encapsulated behavior exposed to apps
- Events – respond to UI related events
ã Composed into a component tree per logical view
- Single “view root” component
- Arbitrary levels of nesting for child components
