JavaServer Faces technology supports various tag libraries to add components to a web page.
To support the JavaServer Faces tag library mechanism, Facelets uses XML namespace declarations.
| Tag Type | Namespace | Prefix | Example | Description |
|---|---|---|---|---|
| Templating | http://java.sun.com/jsf/facelets | ui: | ui:component, ui:insert | Templating |
| HTML | http://java.sun.com/jsf/html | h: | h:head, h:body, h:outputText, h:inputText | |
| JSF | http://java.sun.com/jsf/facelets | f: | f:actionListener, f:attribute | Tags for JavaServer Faces custom actions that are independent of any particular render kit |
| Core | http://java.sun.com/jsf/core | c: | c:forEach, c:catch | Used to perform core actions that are not performed by HTML tags |
| Functions Tags | http://java.sun.com/jsp/jstl/functions | fn: | fn:toUpperCase, fn:toLowerCase | JSTL 1.2 Functions Tags |
| Primeface | http://primefaces.org/ui | p | p:themeSwitcher, p:datatable | Component Library |
In addition, Facelets supports tags for composite components, for which you can declare custom prefixes.
