Using a Managed Bean in a Facelets Page

To use the managed bean in a Facelets page, you typically create a form that uses user interface elements to call its methods and display their results. This example provides a button that asks the user to type a name, retrieves the salutation, then displays the text in a paragraph below the button:

<h:form id="greetme">
   <p><h:outputLabel value="Enter your name: " for="name"/>
      <h:inputText id="name" value="#{}"/></p>
   <p><h:commandButton value="Say Hello" action="#{printer.createSalutation}"/></p>
   <p><h:outputText value="#{printer.salutation}"/></p>
