What is JSF ?

JSF stands for Java Server Faces and blah blah blaah. Among these multiple definitions of JSF I come to keep one that says almost everything in few words and leave the task to anyone to dilute. JSF is a component oriented and event driven web framework to build up web applications. JSF after all is a standard and has many implementations Oracle ADF, Apache MyFaces, IBM and last the one so dear to me is the Sun reference implementation.
 As an event driven and component oriented framework, jsf nice integrate all the members of the MVC:

•  Model: managed beans
• View: components
• Controller: faces servlet

So this is in short how you may look at JSF...
