ssh中jsp页面的数据怎么提交不到action中
在注册页面输入数据后点注册，然后提示空指针异常。
注册页面代码：
<%@ page contentType="text/html;charset=gbk" language="java" %>
<%@taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My JSP 'regist.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body style="background-color: green;">
<div style="margin-top: 100px" align="center">
<h1>普通用户注册</h1>
<hr style="color: black;">
<br>
<s:form action="regist" method="POST">
<s:textfield name="uName" id="uName" label="用户名"></s:textfield>
<br>
<s:password name="uKey" label="密码" size="21"></s:password>
<br>
<s:submit value="注册"/>
</s:form>
</div>
</body>
</html>
注册对应的action：
package com.one.action;
import com.one.bean.UserEntity;
import com.one.service.UserService;
import com.opensymphony.xwork2.ActionSupport;
public class registAction extends ActionSupport {
private UserEntity user;
private String uName;
private String uKey;
public String getuName() {
return uName;
}
