環境：
Windows2003
jdk1.5.05
Eclipse3.1+MyEclipse4.03
做一登錄練習。
現已經完成了login的struts部份，實現了動態ActionForm和動態validator驗證，詳細全部文件內容如下：

}
}
}
ApplicationResources.properties
prompt.username=User Name
prompt.password=User Password
errors.required={0} is required.
ApplicationResources_zh_CN.properties
prompt.username=用戶名稱
prompt.password=登錄密碼
errors.required={0} 是必須的.
validation.xml
<form-validation>
<formset>
<form name="loginForm">
<field property="username" depends="required">
<arg0 key="prompt.username" />
</field>
<field property="password" depends="required">
<arg0 key="prompt.password" />
</field>
</form>
</formset>
</form-validation>
到此已經完成了全部代碼！
