1.从http://www.extremecomponents.org 下载相关的文件
包括相关的Jar包,css和tld文件

2.将extremecomponents-1.0.1.jar放到web-inf/lib下面

3.将下载的images文件夹放到WebRoot目录下面

4.将下载的extremecomponents.css放到WebRoot目录下面的css文件夹下

5.新建一个extremecomponents的测试页面ExtremeCompomentTest_1.jsp：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%@ taglib uri="http://www.extremecomponents.org" prefix="ec" %><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html> <head> <base href="<%=basePath%>"> <title>My JSP 'ExtremeCompomentTest_1.jsp' starting page</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="<%=path%>/css/extremecomponents.css"> </head> <% java.util.List presidents = new java.util.ArrayList(); java.util.Map president = new java.util.HashMap();president.put("name", "George Washington"); president.put("nickname", "Father of His Country"); president.put("term", "1789-1797"); presidents.add(president); president = new java.util.HashMap(); president.put("name", "John Adams"); president.put("nickname", "Atlas of Independence"); president.put("term", "1797-1801"); presidents.add(president); president = new java.util.HashMap(); president.put("name", "Thomas Jefferson"); president.put("nickname", "Man of the People, Sage of Monticello"); president.put("term", "1801-09"); presidents.add(president); president = new java.util.HashMap(); president.put("name", "James Madison"); president.put("nickname", "Father of the Constitution"); president.put("term", "1809-17"); presidents.add(president); president = new java.util.HashMap(); president.put("name", "James Monroe"); president.put("nickname", "The Last Cocked Hat, Era-of-Good-Feelings President"); president.put("term", "1817-25"); presidents.add(president); president = new java.util.HashMap(); president.put("name", "John Adams"); president.put("nickname", "Old Man Eloquent"); president.put("term", "1825-29"); presidents.add(president); request.setAttribute("pres", presidents); %> <body> This is my JSP page. <br> <ec:table items="pres" title="ExtremeCompomentTest" action="${pageContext.request.contextPath}/ExtremeCompomentTest_1.jsp" imagePath="${pageContext.request.contextPath}/images/table/*.gif" rowsDisplayed="2" > <ec:row> <ec:column property="name"></ec:column> <ec:column property="nickname"></ec:column> <ec:column property="term"></ec:column> </ec:row> </ec:table> </body></html>
6.运行页面的效果如下：

7.对测试的Jsp页面-ExtremeCompomentTest_1.jsp进行分析：
  1)在页面中要添加<%@ taglib uri="http://www.extremecomponents.org" prefix="ec" %>
  2)在页面中添加<link rel="stylesheet" type="text/css" href="<%=path%>/css/extremecomponents.css">的Css配置信息
  3)创建一个HashMap，并且将presidents放在request中
   <% java.util.List presidents = new java.util.ArrayList(); java.util.Map president = new java.util.HashMap();president.put("name", "George Washington"); president.put("nickname", "Father of His Country");  president.put("term", "1789-1797"); presidents.add(president); president = new java.util.HashMap();  president.put("name", "John Adams");  president.put("nickname", "Atlas of Independence"); president.put("term", "1797-1801");  presidents.add(president);  president = new java.util.HashMap();  president.put("name", "Thomas Jefferson");  president.put("nickname", "Man of the People, Sage of Monticello"); president.put("term", "1801-09"); presidents.add(president);  president = new java.util.HashMap();  president.put("name", "James Madison"); president.put("nickname", "Father of the Constitution");  president.put("term", "1809-17");  presidents.add(president);  president = new java.util.HashMap(); president.put("name", "James Monroe");  president.put("nickname", "The Last Cocked Hat, Era-of-Good-Feelings President");  president.put("term", "1817-25");  presidents.add(president);  president = new java.util.HashMap();  president.put("name", "John Adams");  president.put("nickname", "Old Man Eloquent");  president.put("term", "1825-29");  presidents.add(president);  request.setAttribute("pres", presidents); %>
  4)对于body中的数据
   <ec:table items="pres"             title="ExtremeCompomentTest"             action="${pageContext.request.contextPath}/ExtremeCompomentTest_1.jsp"             imagePath="${pageContext.request.contextPath}/images/table/*.gif"             rowsDisplayed="2"             >       <ec:row>          <ec:column property="name"></ec:column>          <ec:column property="nickname"></ec:column>          <ec:column property="term"></ec:column>       </ec:row> </ec:table>
  其中的items="pres"是数据源，title="ExtremeCompomentTest"是table的头信息，imagePath是图片的路径，rowsDisplayed是每页显示的记录数目，action是点击下页，前页时要跳转的页面。
