Facelets

Also known as view

In computing, Facelets is an open-source Web template system under the Apache license and the default view handler technology (aka view declaration language) for Jakarta Faces (JSF; formerly Jakarta Server Faces and JavaServer Faces). The language requires valid input XML documents to work. Facelets supports all of the JSF UI components and focuses completely on building the JSF component tree, reflecting the view for a JSF application.
