求一个struts 1.3中validator-rules.xml

[tomsmish]

刚把一个应用程序中的struts1.2换成了1.3,结果validator部分出错了,老出现
No such validation method: MyValidator.CheckUserName.checkUserName(java.lang.Object, org.apache.commons.validator.ValidatorAction, org.apache.commons.validator.Field, org.apache.struts.action.ActionMessages, org.apache.commons.validator.Validator, javax.servlet.http.HttpServletRequest)

好像是1.3版本的validator是6个参数,之前的是5个,多一个org.apache.commons.validator.Validator.
