各项配置已经配置好了还是有 No result defined** 配置报错

首先是页面：这里没有用s标签，是因为我需要用第三方的前端框架，用了s标签那些就不可以用了

<form action="users/reg.action" method="post" name="regForm">
<div class="control-group">
<input type="text" name="mail" placeholder="您的邮箱" /> 
</div>
<div class="control-group">
<input type="password"  name="pswd1" placeholder="您的密码" />
</div>
<div class="control-group">
<input type="password"  name="pswd2" placeholder="请确认密码" />
</div>
<div class="control-group">
<input type="text" name="name" placeholder="您的姓名" /> 
</div>
<div class="control-group">
<input type="text"  name="phone" value="" placeholder="您的手机号码(非必填)" />
</div>
</div>
<button class="btn" data-dismiss="modal" aria-hidden="true">关闭</button>
<input type="submit" class="btn btn-primary" value="确定注册" />

<constant name="struts.i18n.encoding" value="UTF-8" />
	<constant name="struts.configuration.xml.reload" value="true"></constant>
	<constant name="struts.objectFactory" value="spring"/>
	<package name="UserPart" extends="struts-default" namespace="/users">

	<action name="login" class="loginAction" >
		<result name="success">/u/index.jsp</result>
		<result name="input">/index.jsp</result>
	</action>
	<action name="reg" class="regAction">
		<result name="input">/index.jsp</result>
		<result name="success">/u/reg.jsp</result>
	</action></package>

public String execute() {
		if (!pswd1.equals(pswd2))
			return INPUT;
		if (name.length() > 15)
			return INPUT;
		if (mail.indexOf("@") < 1
				|| mail.lastIndexOf(".") < mail.lastIndexOf("@"))
			return INPUT;
		Users user = usersService.getByMail(mail);
		if (user == null)
			return INPUT;
		String password = MD5.md5s(pswd1);
		usersService.addUser(mail, password, name, phone);
		return SUCCESS;

	}

<bean id="regAction" class="com.hzdaily.action.regAction" scope="prototype">
		<property name="usersService" ref="usersService"/>
	</bean>

还有web.xml，应该也是没问题的，现在是控制台不打错误了，而网页页面会是这样，但是既然已经提示了准确的Action名称，而且在相应的execute自行打印其他字符的时候，也确认是执行了execute方法。
