Cannot find bean vlist in scope request??大家帮忙啊，三天了

Question

怎么不直接不list存到request里呢？

Answer 1

id="vlist"  name="vlist  不要同名

Answer 2

在logic:iterator标签中，会将id="vlist"定义的调用request.setAttribute("vlist",vlist); 
而你的name="vlist"中指定的对象也在request中,所以

Answer 3

<logic:iterate id="vlist"  name="vlist" scope="request">
    这个改成<logic:iterate id="v"  name="vlist" scope="request">
还是出现Cannot find bean vlist in scope request??
真是奇怪了，

Answer 4

<%int i=1;%>
  <logic:iterate id="listv"  name="vlist"   scope="request">
     <tr>
        <td align="center">
           <%out.print(i);i++;%>
        </td>
        <td height="29" align="center" >
