tomcat 启动报错 struts版本问题？

[奥尔良烤堡]

昨天晚上项目运行的很正常，今天早上开机后，启动tomcat，总是报错，发现该项目无法编译，分析报错信息可能是struts版本问题，自己以前引用的该SSH框架的架包的所有项目，也都在今天突然无法启动tomcat，求助各位，谢谢。
这是我struts.xml配置信息：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"
"http://struts.apache.org/dtds/struts-2.1.dtd">
这是tomcat启动报错信息：
