<table>

<logic:iterator id="item" name="list">

   <tr>

      <td><bean:write name="item" property="vo对象的属性名"/></td>

      <td><bean:write name="item" property="vo对象的属性名"/></td>

      <td><bean:write name="item" property="vo对象的属性名"/></td>

      <td><bean:write name="item" property="vo对象的属性名"/></td>

   </tr>

</logic:iterator>

</table>

我感觉是自动加载action出的问题

应该是你的JSP代码写的有问题.

struts标签应该没有问题.

Source not found for JspServletWrapper.handleJspException(Exception) line: 473

<logic:present name="TeaList" scope="session">

<logic:iterate id="it" name="TeaList" scope="session" type="com.xxx.Vo">

  <bean:write name="it" property="teaId"/>

  </logic:iterate> 

</logic:present>

别忘了如果teaId是数字的话，要加上
<bean:write name="it" property="teaId" format="#"/>

Action中的代码
TeacherService teaService = new TeacherService() ;
List list = null ;
list = teaService.queryAll() ;
HttpSession session = request.getSession() ;
session.setAttribute("TeaList", list);
String path ="addacticle";

return mapping.findForward(path);
