UI Component Tag - Part 2

Creating a Menu Backing Bean

Now we will create a backing bean which holds the list of  MenuItems. Below shown  is the class

package com.jsflessons.facelets.example;
import java.util.ArrayList;
import java.util.Collection;
public class MenuBackingBean {
     private Collection<MenuItem> menus;
     public Collection<MenuItem> getMenus() {
         return menus;
     public void setMenus(Collection<MenuItem> menus) {
         this.menus = menus;
     public MenuBackingBean() {
         menus = new ArrayList<MenuItem>();
         menus.add(new MenuItem("home.xhtml", "Home"));
         menus.add(new MenuItem("news.xhtml", "News"));
         menus.add(new MenuItem("articles.xhtml", "Articles"));
         menus.add(new MenuItem("about.xhtml", "About Us"));

Configure the managed bean in faces-config.xml.

In the Project Explorer, expand the node, JSFFaceletsExample->WebContent. Double-click on faces-config.xml. This will launch the Faces Configuration editor. Select the ManagedBean tab. Click on the Add button. This will launch the New Managed Bean wizard. Select the option, "Using an existing Java class". In the next wizard panel, search for the class we created, Click Ok button. Select the scope as request and click Finish.
Now we have registered class as a managed bean. Save the Faces Configuration editor. Select source tab. Your  faces-config.xml file should have the following code.


Now we need to create facelets page for the 'side menu'. (Click Next to Continue..)
