validator-rules.xml文件是在strut1.2.9-lib中找到的。對應于每一個版本的struts都有該文件，一般不去修改其中的代碼

資源文件applicationResource.properties
errors.required={0} is required.
errors.minlength={0} can not be less than {1} characters.
errors.maxlength={0} can not be greater than {1} characters.
name=name
password=password
login=login

# Errors
errors.header=<h3><font color"="red">Validation "u9519"u8BEF"uFF01"uFF01"uFF01</font>
