大侠们 为什么我的jsp中的form表单无法提交到Servlet啊？求
jsp页面代码如下：<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
<title>查询供应商页面</title>
</head>
<body><center>
<form action="${pageContext.request.contextPath }/servlet/ProviderServlet？action=listCondPro" name="1" id="1">
<table class="ctable" width="60%">
<tr>
<th width="20%">供应商关键字</th>
<td >
<input type="text" id="provName" name="provName">
</td></tr>
<tr>
<th>供应商单位关键字</th>
<td>
<input type="text" id="department" name="department">
</td></tr>
<tr>
<th>供应商类型关键字</th>
<td>
<select name="type">
<option>--请选择供应商类型--</option>
<option value="1">--重要供应商--</option>
<option value="2">--一般供应商--</option>
</select>
</td></tr>
</table>
<div class="tbar">
<input type="submit" value="确定" id="toSave">
</div>
</form> </center>
</body></html>
这个表单根本就进不了servlet，报的错误如下：
java.lang.NullPointerException

谢谢啊 不过刚又出现个事情， SELECT * FROM `hs_oms_provider` WHERE provName LIKE '%8%';这句话在图形界面中能查出来两条记录，为什么在我的web项目中之查询出来一条记录啊
