Creating the Web Page

In a typical Facelets application, web pages are created in XHTML. The example web page, beanhello.xhtml, is a simple XHTML page. It has the following content:

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://java.sun.com/jsf/html">
    <h:head>
        <title>Facelets Hello World</title>
    </h:head>
    <h:body>
        #{hello.world}
    </h:body>
</html>

A Facelets XHTML web page can also contain several other elements, which are covered later in this tutorial.

The web page connects to the backing bean through the Expression Language (EL) value expression #{hello.world}, which retrieves the value of the world property from the backing bean Hello. Note the use of hello to reference the backing bean Hello. If no name is specified in the @ManagedBean annotation, the backing bean is always accessed with the first letter of the class name in lowercase.
