JSTL异常
这是我写的一个分页的例子 在测试的过程中出了点问题 直接上代码
<body>
<div>
<table>
<tr>
<th>省区编号</th><th>省名</th><th>状态</th><th>创建时间</th>
</tr>
<c:choose>
<c:when test="${empty pl.items}">
<tr align="center">
<td colspan="3">
没有用户
</td>
</tr>
</c:when>
<c:otherwise>
<c:forEach var="baseProvinces" items="${pl.items}">
<tr align="center">
<form action="register!updateUser" method="post">
<td>
<input type="text" name="baseProvinces.provincesId" value="${baseProvinces.provincesId}"></input>
</td>
<td>
<input type="text" name="baseProvinces.provincesName" value="${baseProvinces.provincesName}"></input>
</td>
<td>
<input type="text" name="baseProvinces.state" value="${baseProvinces.state}"></input>
</td>
<td>
<input type="text" name="baseProvinces.creationDate" value="${baseProvinces.creationDate}"></input>
</td>
<td>
<input type="submit" value="修改"/>
<a href="register!delUser?id=${baseProvinces.provincesId}">删除</a>
</td>
</form>
</tr>
</c:forEach>
</c:otherwise>
</c:choose>

</c:when>这段代码删了 但是还是说有异常。 顺便问下<c:choose> 和<c:otherwise>标签是干什么用的 为什么要把 <c:when> 和 <c:forEach>包含
