JSF libraries need to be added in an application.

On the .jsp page, a tag library needs to be added:

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

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

In an XML style:

<?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">

The JSF components can be accessed using the prefix attached.

In an IDE, JSF can be added easily. However, when working without them the faces-config.xml needs to be updated and populated with classes i.e. Managed Beans between the following tags

<faces-config> </faces-config>
