如果你的rs没有关闭，应该没有问题，不过一般是不在jsp里做和数据库相关的操作。

以上源代码
如果checkbox里不为<%=rs.getString("id")%>没有任何的问题！
出错提示！！！

这样<input type="checkbox" name="id" value='<%=rs.getString("id")%>'>
这样<input type="checkbox" name="id" value='<%=rs.getString(\"id\")%>'>
都不行的！
还是出错！！！

[daeren]

<input type="checkbox" name="id" ><%=rs.getString("id")%>
也不行！
怎么拉？

[niyboy]

下面这句话不能这样写：
<input type="checkbox" name="id" value="<%=rs.getString("id")%>"></p>
把他改为：
<input type="checkbox" name="id" ><%=rs.getString("id")%>

[liuxiaobo8590]

<input type="checkbox" name="id" value="<%=rs.getString("id")%>">
把他改为：
