环境：
Windows2003
jdk1.5.05
Eclipse3.1+MyEclipse4.03
做一登录练习。
现已经完成了login的struts部份，实现了动态ActionForm和动态validator验证，详细全部文件内容如下：

}
ApplicationResources.properties
prompt.username=User Name
prompt.password=User Password
errors.required={0} is required.
ApplicationResources_zh_CN.properties
prompt.username=用户名称
prompt.password=登录密码
errors.required={0} 是必须的.
validation.xml
<form-validation>
<formset>
<form name="loginForm">
<field property="username" depends="required">
<arg0 key="prompt.username" />
</field>
<field property="password" depends="required">

</field>
</form>
</formset>
</form-validation>
到此已经完成了全部代码！
