JSF 面试题与答案

Question: How the components of JSF are rendered? An Example

Answer: In an application add the JSF libraries. Further in the .jsp page one has to add the tag library like:
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>

Or one can try XML style as well:
<?xml version="1.0"?> <jsp:root version="2.0" xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html">

Once this is done, one can access the JSF components using the prefix attached. If working with an IDE (Integrated Development Environment) one can easily add JSF but when working without them one also has to update/make the faces-config.xml and have to populate the file with classes i.e. Managed Beans between
<faces-config> </faces-config> tags
