JSF 2 Include Example

March 27, 2014 by Amr Mohammed Leave a Comment

Facelets was originally developed as an alternative to the JSP-based view handler in JSF1.x. In JSF 2.0 facelets replaces JSP as JSF’s default view technology. In addition to being a better view handler, Facelets supports a number of tags and one of them is a tag for including content from other XHTML pages.
