index.jsp：

只有一个超链接

<a href="../news/listNews.html">查看新闻列表</a>

newslist.jsp：

<body topmargin="0">
<table id="newslist" cellpadding="7" cellspacing="3" border="0" align="center" width="70%" bordercolor="#FF6600">
	<tr>
    	<td colspan="2"><a href="index.html">首页</a> &gt;&gt; 新闻列表</td>
    </tr>
	<tr>
    	<td class="title" colspan="2">新闻列表</td>
    </tr>
    <c:forEach items="${newss}" var="news">
	<tr>
    	<td width="70%" align="left"><a href="../news/showNews_${news.newsid }.html">${news.title }</a></td>
        <td width="30%" align="right">发布时间：${news.addtime }</td>
    </tr>
    </c:forEach>
</table>
</body>

showNews.jsp：

<body topmargin="0">
<div id="con">
<table cellpadding="7" cellspacing="3" border="0" align="center" width="100%" bordercolor="#FF6600">
	<tr>
    	<td><a href="index.html">首页</a> &gt;&gt; <a href="listNews.html">新闻列表</a> &gt;&gt; ${news.title }</td>
    </tr>
	<tr>
    	<th class="title">${news.title }</th>
    </tr>
	<tr>
    	<td align="right">来源网址：${news.author } 发表时间：${news.addtime }</td>
    </tr>
    <tr>
    	<td bgcolor="#E8F2FE" class="content">${news.intro }</td>
    </tr>
    <tr>
    	<td class="content">${news.content }</td>
    </tr>
</table>
</div>
<div id="listnew">
	<span style="float: right;height: 30px; width: 100%;position: relative; margin-left: 50px;">新闻列表</span>
	<c:forEach items="${newss }" var="neww">
		<li><a href="../news/showNews_${neww.newsid }.html">${neww.title }</a></li>
	</c:forEach>
</div>
</body>

效果图：

第一张：这个是列出了全部的新闻标题，如果没有UrlRewrite的话，地址栏实际显示的应该是

http://localhost:8080/fkw/servlet/NewsServlet2?action=listNews

而经过UrlRewrite，目前如下显示

下面每一条新闻标题的超链接都是：http://localhost:8080/fkw/news/showNews_newid.html

newsid为每一条新闻的id

第二张图：

这张是对某一条新闻的具体显示

实际访问的地址其实是：

http://localhost:8080/fkw/servlet/NewsServlet2?action=getNews&newsid=3

现在如下显示
