An API for representing components and managing their state; handling events, server-side validation, and data conversion; defining page navigation; supporting internationalization and accessibility; and providing extensibility for all these features.
What are UI components in Java?
JavaServer Faces components are the building blocks of a JavaServer Faces view. A component can be a user interface (UI) component or a non-UI component. JavaServer Faces UI components are configurable, reusable elements that compose the user interfaces of JavaServer Faces applications.
