建了个没带Form、Action的JSP的页面,想迭代出数据库里某表某字段的全部记录!(在线等)
jsp里的代码:
<%@   page   language= "java "   pageEncoding= "GBK "%>
<%@   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 "   %>
  <jsp:useBean   id= "web_menuVO "   class= "com.kzon.DAO.web_menuDao "   scope= "page "> </jsp:useBean>
  <bean:define   id= "vo "   name= "web_menuVO "   property= "firstmenu_name "> </bean:define>

<html:html   lang= "true ">
    <head>
        <html:base   />
       
        <title> menu.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>
    <logic:iterate   id= "vo ">
    <table>
    <tr>
    <th> 目录名 </th>
    </tr>
    <tr>
    <td>
    <bean:write   name= "vo "   property= "menu_name "/>
    </td>
    </tr>
    </table>
    </logic:iterate>
       
    </body>
</html:html>

启动服务后报:
