JSF Key Concepts

• JSF includes the following concepts:

• UI component, including renderers and render kits
• Controller: The navigation rules that govern page flow
• Managed beans and backing beans to encapsulate business logic, data, and properties of components (ADF BC applications define business logic mainly in the model layer, not the UI layer.)
• Life cycle: Creation, validation, data binding and business service interactions of a page

Notes:

JSF Key Concepts

JSF encompasses several key concepts:

UI component: Button, table of data, menu tab

Controller: Navigation rules that define how the user progresses through the application

Managed bean: How business logic and data are specified; note that in an ADF BC application, most business logic and data are defined in the ADF BC model; and most component properties are defined in the ADF binding layer

Backing bean: How the properties of a component are specified

EL: Binding data and methods to UI components (You learn about EL in the lesson titled “Binding UI Components to Data.”)

Life cycle: How the application behaves at run time
