求教Struts2中XXX-validation.xml的配置

首先我有一个：HelloWorld-validation.xml文件 内容为：
<validators>
  <field name ="reqiuredString">
  <field-validator type ="requiredstring">
  < message > This string is required </ message >
  </field-validator >
  </field >
</validators >
现在我想中文时输出：字符串不能为空，英文时输出：This string is required
已经文件：globalMessages_en_US.properties，内容：reqiuredString=This string is required；
globalMessages_zh_CN.properties，内容：reqiuredString=字符串不能为空。

最後：HelloWorld-validation.xml中 < message > This string is required </ message > 应该怎麼改呢，求教，谢谢。

難道沒人知道嗎？

估计做不到

这个xml里面大概做不到 要不你写在这个方法的签名写一个 方法名validae（）{然后判断} 或者js是不是能写

如果不行，那么在項目中如果是中文的錯誤給出中文的錯誤提示，英文的給出英文錯誤提示，大家有什麽方法，能不能交流一下?

你在登录时 选择中文界面 就显示中文的错误提示 使用全英文的界面 就用英文提示了  
globalMessages_en_US.properties，内容：reqiuredString=This string is required；
globalMessages_zh_CN.properties，内容：reqiuredString=字符串不能为空
就是你这个意思 就是差了一步小小的选择语言吧

<message key="reqiuredString" /> 这样不行？
