一、web.xml

<display-name>Facelets Tutorial</display-name>
    <description>Number Guess Game</description>
    <!-- Change to "Production" when you are ready to deploy -->
    <context-param>
        <param-name>javax.faces.PROJECT_STAGE</param-name>
        <param-value>Development</param-value>
    </context-param>
    <!-- Faces Servlet -->
    <servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <!-- Faces Servlet Mapping -->
    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>/faces/*</url-pattern>
    </servlet-mapping>
    <!-- welcome file mapping -->
    <welcome-file-list>
        <welcome-file>faces/hello.xhtml</welcome-file>
    </welcome-file-list>

二、添加jar包

三、页面

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:f="http://java.sun.com/jsf/core"      
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:ui="http://java.sun.com/jsf/facelets">
    <f:view contentType="text/html"/>
    <h:head>
        <title>Hello World!</title>
    </h:head>
    <h:panelGrid columns="2" border="1">
    	<f:facet name="abc">
    	<h:outputText value="#{helloBean.name}"></h:outputText>
    	</f:facet>
    	<ui:repeat var="list" value="#{helloBean.lists }">
    		<h:outputText value="#{list.name}"></h:outputText>
    	
    	</ui:repeat>
    </h:panelGrid>
    <h:body bgcolor="white">
        <h2>My name is Duke.  What is yours?</h2>
        <h:form id="helloForm" >
            <h:graphicImage id="waveImg" url="#{resource['wave.med.gif']}" />
            <h:inputText id="username" value="#{helloBean.name}"/>
            <h:commandButton id="submit" action="response" value="Submit"/>
        </h:form>
    </h:body>
</html>

四、helloBean

package helloworld;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;

@ManagedBean
@SessionScoped
public class HelloBean implements Serializable {

   private String name;
   private List<HelloBean> lists;

   public String getName() { return name;}
   
   public void setName(String name) { this.name = name; }

public List<HelloBean> getLists() {
	lists=new ArrayList<HelloBean>();
	HelloBean h=new HelloBean();
	h.setName("dong");
	lists.add(h);
	h.setName("dongdong");
	lists.add(h);
	return lists;
}

public void setLists(List<HelloBean> lists) {
	this.lists = lists;
}
   
}
