Introduction to JSF
JavaServer Faces (JSF) is a Java-based web application framework intended to simplify development integration of web-based user interfaces. JavaServer Faces is a standardized display technology which was formalized in a specification through the Java Community Process.
JavaServer Faces (JSF) is a MVC web framework that simplifies the construction of user interfaces (UI) for server-based applications by using reusable UI components in a page.JSF provides facility to connect UI widgets with data sources and to server-side event handlers. The JSF specification defines a set of standard UI components and provides an Application Programming Interface (API) for developing components.JSF enables the reuse and extension of the existing standard UI components.
JSF reduces the effort in creating and maintaining applications which will run on a Java application server and will render application UI on to a target client.JSF facilitates Web application development by
- providing reusable UI components
- making easy data transfer between UI components
- managing UI state across multiple server requests
- enabling implementation of custom components
- wiring client side event to server side application code
JSF UI component model
JSF provides developers capability to create Web application from collections of UI components that can render themselves in different ways for multiple client types (for example HTML browser, wireless or WAP device).
- Core library
- A set of base UI components – standard HTML input elements
- Extension of the base UI components to create additional UI component libraries or to extend existing components.
- Multiple rendering capabilities that enable JSF UI components to render themselves differently depending on the client types
