Facelets Files Used in the Main Interface
The Duke's Tutoring application uses Facelets to display the user interface, and makes
extensive use of the templating features of Facelets. Facelets is the default display tech-
nology for JavaServer Faces, and consists of XHTML files located in the tut-install /ex-
amples/case-studies/dukes-tutoring/dukes-tutoring-war/web/
directory.
The following Facelets files are used in the main interface:
