为何遍历不出来

<% List<user> users=new PrimaryDao().listUser(); %>
	<table  width="60%" border="1" cellpadding="0" cellspacing="0">
			<tr align="center">
				<td>id</td><td>uname</td><td>email</td><td>note</td><td>s.count</td>
			</tr>
		<c:forEach items="${users}" var="u" varStatus="s">
			<tr>
				<td>${u.id}</td>
				<td>${u.uname}</td>
				<td>${u.email}</td>
				<td>${u.note}</td>
			</tr>
		</c:forEach>
	</table>
