Java EE 6: JSF vs Servlet + JSP. Should I bother learning JSF?
- by Harry Pham
I am trying to get familiar with Java EE 6 by reading http://java.sun.com/javaee/6/docs/tutorial/doc/gexaf.html. I am a bit confused about the use of JSF.
Usually, the way I develop my Web App would be, Servlet would act like a controller and JSP would act like a View in an MVC model. So Does JSF try to replace this structure? Below are the quote from the above tutorial:
Servlet are best suited for service-oriented App and control function of presentation-oriented App like dispatching request
JSF and Facelet are more appropriated for generating mark-up like XHTML, and generally used for presentation-oriented App
Not sure if I understand the above quote too well, they did not explain too well what is service-oriented vs presentation-oriented.
A JavaServer Faces application can map HTTP requests to component-specific event handling and manage components as stateful objects on the server.
Any knowledgeable Java developer out there can give me a quick overview about JSF, JSP and Servlet? Do I integrate them all, or do I use them separated base on the App? if so then what kind of app use JSF in contrast with Servlet and JSP
A JavaServer Faces application can map HTTP requests to component-specific event handling and manage components as stateful objects on the server.
Sound like what servlet can do, but not sure about manage components as stateful objects on the server. Not even sure what that mean? Thanks in advance.
