------解决思路----------------------
Struts2.0 用的是这个filter吧(org.apache.struts2.dispatcher.FilterDispatcher)
Struts2.3以后才用的org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

1、把项目的目录结构贴出来看看
2、把导入的jar包也截个图贴出来

ps:最好找个Struts自带的demo导入进来看看(这样可以保证strut对应的jar包配置都是正确的)
------解决思路----------------------
照你给的资料看来,这是缺少相应jar包的问题,你用的与struts2相关的jar文件值得怀疑,你自己确认一下吧
