资源文件：
# Resources for parameter 'com.yourcompany.struts.ApplicationResources'
# Project Test1
userName.error=UserName is wrong!
passWord.error=PassWord is wrong!
addUser.success=Add user is success!
addUser.false=Add user is false!
name=UserName
userName={0}'s length can not > {1}
页面使用的是<html:errors />来输出！
还有请问下：
<arg0 key="name" />
<arg1 name="maxlength" key="${var:maxlength}"
resource="false" />
到底是什么意思啊？
那个key=“name” 是不是要进资源文件读取啊？
