推荐答案

Struts配置文件中的标记错误.它应该是<struts>.文件名称应为struts.xml.该文件应位于类路径上，即WEB-INF/classes文件夹中.还应该有一个动作课.

You have wrong tag in the Struts configuration file. It should be <struts>. And the name of the file should be struts.xml. This file should be on classpath i.e. in the WEB-INF/classes folder. There should also be an action class.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
   "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
   "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
    <package name="default" extends="struts-default">
        <action name="getTutorial" class="org.tutorial.action.StrutsAction">
           <result name="success">/success.jsp</result>
           <result name="error">/failure.jsp</result>
        </action>
    </package>
</struts>
