There is no Action mapped for namespace / and action name >. - [unknown location

阅读更多

今天访问一个链接后台出现这个错误了,但是已经跳转到指定页面,晚上查找都说package的namespace的问题,后者xml配置文件名称错误的问题,因为strust2默认要加载一些配置文件,经分析都不是以上原因造成的,因为我成功跳转到指定页面,访问action是没有任何问题的,后来查看跳转页面很汗的是,

原来是在拷贝代码的时候没有配置标签<%@ taglib prefix="s" uri="/struts-tags"%>

配上后后台异常问题解决了
