关于servlet获取页面时间控件值的问题，获取后总提示格式转换错误
我想获得控件值后，将二个时间段的值传到数据库查询，我用试着用SIMPLEDATAFORMAT转换，可还是不行
这是取值的servlet
response.setCharacterEncoding("gbk");
response.setContentType("text/html");
String starttime=request.getParameter("starttime");
String endtime=request.getParameter("endtime");
SimpleDateFormat format=new SimpleDateFormat("");
OperatorQuery query=new OperatorQuery();
List list=query.queryFeeList(starttime, endtime);
HttpSession session=request.getSession();
session.setAttribute("list", list);
// request.getRequestDispatcher("/projectdataquery/luhag.jsp").forward(request, response);
response.sendRedirect("/projectdataquery/luhag.jsp");
这是页面对应的html
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gbk">

<link rel="stylesheet" type="text/css" href="styles.css"> -->

</tr>
<tr>
<td height="180"><input type="submit" name="submit" value="提交"/></td>
</tr>
</table>
</form>
</body>

这是报的错误提示
