1)struts.xml

<action name="Logon" class="com.meetcomet.action.logon">
<result name="input">/login.jsp</result>
<result name="success">/welcome.jsp</result>
<result name="error">/error.jsp</result>
</action>

2)login.jsp

<%@page language="java"import="java.util.*"pageEncoding="GBK"%>
<%@taglib prefix="s"uri="/struts-tags"%>
<html>
<body>

<s:text name="greetings"></s:text><br>
<s:form action="Logon"  method="post" >
<s:textfield key="username"/>
<s:textfield key="password"/>
<s:textfield key="email"/>
<s:submit value="确定"/>
</s:form><s:text name="contact"></s:text>
</body>
</html>

4)Logon中没有验证代码

5）在和Logon同一位置文件名为logon.java，建立的验证文件logon-validation.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC
"-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">

<validators>
<field name="username">
<field-validator type="requiredstring">
<message>账号不能为空</message>
</field-validator>
</field>

<field name="password">
<field-validator type="requiredstring">
<message>密码不能为空</message>
</field-validator>
<field-validator type="stringlength">
<param name="minLength">6</param>
<param name="maxLength">10</param>
<message>密码在 ${minLength} -${maxLength}位之间</message>
</field-validator>
</field>

<field    name="email">
<field-validator type="requiredstring">
<message>email不能为空</message>
</field-validator>
<field-validator type="email">
<message>非email格式</message>
</field-validator>
</field>

</validators>

6)国际化可为

<field name="email">
<field-validator type="requiredstring">
<message>${getText("login.email.isnull")</message>
</field-validator>
<field-validator type="email">
<message>${getText("login.email.noEmail")</message>
</field-validator>
</field>

后来发现，login的action名字还是用login比较好，而不要用自己编的logon，因为Action.LOGIN这个值为"login".
