Question: What are tags in JSF ?

Answer: JSF application typically uses JSP pages to represent views. JSF provides useful special tags to enhance these views. Each tag gives rise to an associated component. JSF (Sun Implementation) provides 43 tags in two standard JSF tag libraries:

1. JSF Core Tags Library
2. JSF Html Tags Library

Even a very simple page uses tags from both libraries. These tags can be used adding the following lines of code at the head of the page.

<%@ taglib uri=”http://java.sun.com/jsf/core “ prefix=”f” %> (For Core Tags)
<%@ taglib uri=”http://java.sun.com/jsf/html “ prefix=”h” %> (For Html Tags)
