What is JSF? Introducing JavaServer Faces
See the original posting on JavaWorld
JavaServer Faces (JSF) is the Java standard technology for building component-based, event-oriented web interfaces. Like JavaServer Pages (JSP), JSF allows access to server-side data and logic. Unlike JSP, which is essentially an HTML page imbued with server-side capabilities, JSF is an XML document that represents formal components in a logical tree. JSF components are backed by Java objects, which are independent of the HTML and have the full range of Java abilities, including accessing remote APIs and databases.
