Answer 1

struts2-core.jar
xwork.jar
ognl.jar
freeer.jar
commons-logging.jar
commons-fileupload.jar注：版本对应你用的struts2的版本即可。

Answer 2

如果加上以上6个jar还报错<filter>
      <filter-name>struts2</filter-name>
      <filter-class>
          org.apache.struts2.dispatcher.FilterDispatcher
      </filter-class>
  </filter>
  <filter-mapping>
      <filter-name>struts2</filter-name>
      <url-pattern>/*</url-pattern>  </filter-mapping>

Answer 3

Struts2的过滤器拦截路径最好是/*, 不要随便去修改这个路径,  否则你访问Struts2核心包中的静态资源的时候会出问题的.!
