  1.   

    不是你说的情况，具体的我的文件如下;
    template.jsp
    ---------------
    <%@page errorPage="errorpage.jsp" %>
    <%@page contentType="text/html;charset=GBK"%>
    <%@ taglib uri="/WEB-INF/tlds/taglib.tld" prefix="j2ee" %><html>
      <head>
        <title>
          <j2ee:insert parameter="HtmlTitle" />
        </title>
      </head>  <body bgcolor="white">
        <j2ee:insert parameter="HtmlBanner" />
        <j2ee:insert parameter="HtmlTopIndex" />
        <table height="85%" width="100%"  cellspacing="0" border="0">
         <tr>
         <td valign="top">
            <j2ee:insert parameter="HtmlBody" />
           </td>
         </tr>
         <tr>
          <td valign="top">
            <j2ee:insert parameter="HtmlPetFooter" />
          </td>
         </tr>
         <tr>
          <td valign="bottom">
            <j2ee:insert parameter="HtmlFooter" />
          </td>
         </tr>
        </table>
      </body>
    </html>
    注：在每个insert tag 中引入页面，机制是通过xml文件映射，在"htmlBody"中引入下面的jsp
