<struts> <package name="default" namespace="/" extends="struts-default" strict-method-invocation="false"> <action name="*_*" method="{2}" class="com.cailiang.action.{1}Action"> <result>/result.jsp</result> <result name="add">/{2}.jsp</result> <result name="update">/{2}.jsp</result> <allowed-methods>add,update</allowed-methods> </action> </package> <constant name="struts.enable.DynamicMethodInvocation" value="false"></constant> </struts> -

看看你的报错，namespace的问题。

肯定不对啊，action name="helloworld_*" method="{1}" 表示你响应的只能是helloworld_*.action的动作，比如说响应helloworld_login.action，而method{N}代表前面的第N个*匹配子串，意思是跳转到login.jsp页面。看看你有写了这些相应的action没，以及jsp页面有与之对应的没
