Answer 1

你的包没有加载上struts2-core-2.2.3.1.jar!/struts-default.xml

web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.5" 

xmlns="http://java.sun.com/xml/ns/javaee"; 

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee ;

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd";>

 <filter>

        <filter-name>struts2</filter-name>

        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

    </filter>

    <filter-mapping>

        <filter-name>struts2</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>

    

  <welcome-file-list>

    <welcome-file>index.jsp</welcome-file>

  </welcome-file-list>

</web-app>

其他应该比较简单了

Answer 2

HelloWorld/WEB-INF/lib/struts2-core-2.2.3.1.jar!/struts-default.xml:29:72
通过上面看出，struts-default.xml文件中29行有错误。也可能是其他地方导致的，比如你的Struts的过滤器路径是否配置正确。可以先把struts-default.xml文件内容贴出来看一下。

Answer 3

一定是缺少了一些jar包，struts2.2.3一般最少需要9个包
