[b]1.在你的struts配置文件struts-config.xml中加入下面的配置：[/b]


<plug-in className="org.apache.struts.tiles.TilesPlugin" >
    <!-- Path to XML definition file -->
    <set-property property="definitions-config" value="/WEB-INF/tiles-defs.xml" />
    <set-property property="moduleAware" value="true" />
  </plug-in>

[b]2.生成tiles-def.xml文件（/WEB-INF/tiles-def.xml）：[/b]


<?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE tiles-definitions PUBLIC 
       "-//Apache Software Foundation//DTD Tiles Configuration 1.1//EN" 
       "http://jakarta.apache.org/struts/dtds/tiles-config_1_1.dtd"> 

<tiles-definitions> 

 <definition name="base-definition" path="/layout.jsp"> 
    <put name="sidebar" value="sidebar.jsp"/> 
    <put name="header" value="header.jsp"/> 
    <put name="content" value=""/> 
    <put name="footer" value="footer.jsp"/> 
 </definition> 

 <definition name="index-definition" extends="base-definition"> 
    <put name="content" value="indexContent.jsp"/> 
 </definition> 

</tiles-definitions>

[b]3.生成layout.jsp布局文件:[/b]


<%@ page language="java" pageEncoding="ISO-8859-1"%>

<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>
<%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %>


<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html:html lang="true">
  <head>
    <html:base />

    <title>layout.jsp</title>

	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->

  </head>

  <body>
  <table width="100%" height="100%">  
  <tr>  
  <td width="150" valign="top" align="left" bgcolor="#CCFFCC"> 
      <tiles:insert attribute="sidebar"/>  
  </td>  
  <td valign="top" height="100%" width="*">  
    <table width="100%" height="100%">  
       <tr> <td height="15%"> <tiles:insert attribute="header"/> </td> </tr> 
       <tr> <td valign="top" height="*"> <tiles:insert attribute="content"/> </td></tr> 
      <tr> <td valign="bottom" height="15%"><tiles:insert attribute="footer"/></td></tr> 
    </table>  
  </td>  
</tr>  
</table>  

  </body>
</html:html>

[b]4.生成要使用的JSP文件sidebar.jsp,header.jsp,footer.jsp。 [/b]

[b]5.通过action-mappings配置你的tiles组件：[/b]


<action path="/tilesExam" type="com.yourcompany.struts.action.TilesExamAction">
      <set-property property="cancellable" value="true" />
      <forward name="success" path="index-definition"></forward>
    </action>

[b]只要tilesExam.do的响应一到达，在经过action的内部处理以后，就会转发复合视图来显示。[/b]

[b]6.TilesExamAction类[/b]


/*
 * Generated by MyEclipse Struts
 * Template path: templates/java/JavaClass.vtl
 */
package com.yourcompany.struts.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

/** 
 * MyEclipse Struts
 * Creation date: 04-19-2010
 * 
 * XDoclet definition:
 * @struts.action validate="true"
 */
public class TilesExamAction extends Action {
	/*
	 * Generated Methods
	 */

	/** 
	 * Method execute
	 * @param mapping
	 * @param form
	 * @param request
	 * @param response
	 * @return ActionForward
	 */
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) {
		// TODO Auto-generated method stub
		return mapping.findForward("success");
	}
}

[b]7.index.jsp[/b]


<%@ page contentType="text/html; charset=gb2312" %> 
<%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %> 
<tiles:insert page="layout.jsp" flush="true">   
      <tiles:put name="sidebar" value="sidebar.jsp"/> 
      <tiles:put name="header"  value="header.jsp"/>    
      <tiles:put name="content" value="indexContent.jsp"/>    
      <tiles:put name="footer"  value="footer.jsp"/>    
</tiles:insert>

[b]8.上面的jsp页面也可以写为[/b]


<%@ page contentType="text/html; charset=gb2312" %> 
<%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %> 
<tiles:insert definition="index-definition"/>
