JSF国际化

 <f:inputText ... required="true" />如果为空提交，会报“Validation Error: Value is required.”错误。
如果我要国际化怎么做？
1.在资源文件message_zh_CN.properties和message_语言_国家.properties文件
2.配置faces-config.xml
  <application>
    <message-bundle>myvalidate.message</message-bundle>
    <locale-config>
      <default-locale>zh_CN</default-locale>   <!--默认资源文件-->
      <supported-locale>en</supported-locale>   <!--支持的资源文件-->
      <supported-locale>en_IE</supported-locale>  <!--支持的资源文件-->
    </locale-config>
  </application>
3.在资源文件中建立一个KEY和Value，当然Value需要转成Unicode码。
javax.faces.component.UIInput.REQUIRED=错误信息：必填项

看看是不是成功了？

下面我把默认错误都列出来，只要制作一个就是国际化的错误消息了。
