Question

jsp中报javax.servlet.jsp.el.ELException

javax.servlet.jsp.el.ELException: Unable to find a value for "typeID" in object of class "java.lang.String" using operator "."
jsp中的代码
<c:forEach var="ss" items="${sessionScope.list}">
<tr bgcolor="#faf9f5" onclick="show(this)" ondblclick="change('${ss.userName}','${ss.buMen }')">
<td>${ss.userID}</td>
<td>${ss.userZhanghao}</td>
<Td>${ss.userName}</Td>
<Td>${ss.buMen }</Td>
</tr>
</c:forEach>
servlet中的代码
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

response.setContentType("text/html");
PrintWriter out = response.getWriter();

com.dao.SupplyDao ss=new com.dao.SupplyDao();//dao层的代码没问题
java.util.List<com.JavaBean.Supply> list=ss.selectSupply();
HttpSession session=request.getSession();
session.setAttribute("supply", list);
response.sendRedirect("/jindongli/show/showSupply.jsp");

}

请高手指点一下 在线等

Answer 1

<c:forEach var="ss" items="${supply}">
<tr bgcolor="#faf9f5" onclick="show(this)" ondblclick="change('${ss.userName}','${ss.buMen }')">
<td>${ss.userID}</td>
<td>${ss.userZhanghao}</td>
<Td>${ss.userName}</Td>
<Td>${ss.buMen }</Td>
</tr>
</c:forEach>

Answer 2

用session.setAttribute("supply", list);
在页面怎么是items="${sessionScope.list}"？
楼上正解。你看看session.setAttribute的用法吧？

Answer 3

楼主你用一楼的办法试试！问题自己慢慢摸索！session.setAttribute("",);用的是前面的标记后面的啊！在提取的时候要用双引号里面的啊！
