Presentation Overview

• JSF Crash Course
• JBuilders Design Philosophy
• Demo
• Summary
• Q A

5
JSF Crash Course

• JavaServer Faces (JSF) is a user interface (UI)
  framework for Java web applications. It is
  designed to significantly ease the burden of
  writing and maintaining applications that run on
  a Java application server and render their UIs
  back to a target client.
• From JavaServer Faces specification

6
JSF Crash Course

• Oh, the Complexity!
• How to Simplify Identify Your Role
• Backing Beans
• JSF Expression Language
• Programming Models
• Controlling Navigation

7
Identify Your Role

• Application Development
• JSPs, Backing Beans, Navigation, Converters,
  Validators
• Component Development
• Components, Render Kits, Renderers...
• Application Configuration
• Factories, Handlers, Resolvers, etc...

8
Backing Beans

• Referenced Bean Defines the logical name and the
  type of a bean that will be available within one
  of the scopes at runtime.
• Managed Bean Defines the logical name, type, and
  scope of a bean that will be made available via
  the JSF Framework.
• Concrete vs. Dyna
• Managed Properties
• List / Map Entries

9
JSF Expression Language

• Searches in scoped storage for an object by name
• Allows access to the objects methods and
  properties
• Uses the delimiters and

10
JSF Expression Examples

• foo
• foo.bar
• foo.bar.baz
• foobar

• foobar
• foo3
• foo3.bar
• foo.bar3

11
Programming Models

• Value Bound - The component values are bound to
  properties in the backing in beans.
• Advantages
• Clean separation of view and model
• Less casting in business logic
• Covered extensively in books
• Disadvantages
• More difficult to manipulate components
  programmatically

12
Programming Models

• Component Bound - The components are bound to
  properties in the backing in beans.
• Advantages
• Easy to manipulate components programmatically
• Disadvantages
• Need to cast to get meaningful values
• Blurs the line between view and model
• Your results may vary

13
Programming Models

• Which model should I use?
• Have a bias to the Value Bound Model
• but do what you
  need to do.
• Simplicity
• Minimize view/model blending
• If you must, bind components as generically as
  possible

14
Controlling Navigation

• The UICommand Components
• Setting the action attribute
• a hard coded outcome
• method binding expression
• Default Navigation Handler
• The three keys
• From view ID
• From outcome
• From action

15
Controlling Navigation

• Navigation Rule
• From view ID
• The views for which this rule is active
• Can include the wildcard character,
• Collection of Navigation Cases
• Navigation Case
• From outcome
• From action
• To view ID

16
JBuilder Design Philosophy

• Easing development is the goal
• Assume developers will touch the code
• No extra artifacts
• No unnecessary fluff
• Encompass the breadth of the spec
• What elephant?
• 
  ...WYSIWYG

Demo
18
Things to Remember

• Configure JBuilder to your liking
• Sketch your applications flow
• Exploit the JSF Palette
• Exploit code templates
• Let ErrorInsight lead the way

19
Usability Testing

• Testing takes place Monday and Tuesday, 1-5pm, in
  the Computer Lab.
• Testing Areas
• Code generation and manipulation
• Running, debugging, deploying
• Web JSF features
• EJB features
