Introduction to Facelets
The term Facelets refers to the view declaration language for JavaServer Faces technology. JavaServer Pages (JSP) technology, previously used as the presentation technology for JavaServer Faces, does not support all the new features available in JavaServer Faces in the Java EE 6 platform. JSP technology is considered to be a deprecated presentation technology for JavaServer Faces. Facelets is a part of the JavaServer Faces specification and also the preferred presentation technology for building JavaServer Faces technology-based applications.
