Abstract:
JavaServer Faces (JSF) is a Java specification for building component-based user interfaces for web applications.
It was formalized as a standard through the Java Community Process and is part of the Java Platform, Enterprise Edition.
JSF 2 uses Facelets as its default templating system.
Based on a component-driven UI design-model, JavaServer Faces uses XML files called view templates or Facelets views.
The FacesServlet processes requests, loads the appropriate view template, builds a component tree,
processes events, and renders the response (typically in the HTML language) to the client.
The state of UI components and other objects of scope interest is saved at
the end of each request in a process called stateSaving (note: transient true),
and restored upon next creation of that view.
