jstl标签如何遍历request中的对象.
请给出代码示例. 
 我request中放入 
 request.setAttribute( "quesList ",   quesList); 
 quesList是dto.   
 想用for   each标签遍历出来.   
                 <c:forEach   var= "ques "   items= "quesList ">  
  <tr>  
              <td>  
                                <c:out   value= "${ques.id} "   />  
              </td>  
              <td>  
              <input   type= "text "   id= "question "   value= "${question.content} ">  
              </td>  
  </tr>  
  </c:forEach>  
 出现  
org.apache.jasper.JasperException:   /WEB-INF/jsp/question/listques.jsp(56,7)   According   to   TLD   or   attribute   directive   in   tag   file,   attribute   value   does   not   accept   any   expressions 
 错误,急死我了. 
 请给出代码示例.   
------解决方案-------------------- <input type= "text " id= "question " value= "${question.content} ">  
 里的value应该是value= "${ques.content} "吧?

------解决方案--------------------帮顶~~
------解决方案--------------------标签的标签库没有引入 
 还有就是根本没这个一个标签
------解决方案-------------------- <c:forEach var= "ques " items= "${quesList} ">  
  <tr>  
      <td>  
            <c:out value= "${ques.id} " />  
      </td>  
      <td>  
      <input type= "text " id= "question " value= "${question.content} ">  
      </td>  
  </tr>  
  </c:forEach>  
------解决方案--------------------JSP页面上加: 
  <%@ taglib uri=http://java.sun.com/jstl/core_rt prefix= "c "%>  
 或者自己配置c_rt标签
