红色字体为出错信息，原来以为是用Filter（过滤器或者拦截器）出错，因为把把web.xml里的filter配置去掉，就正常起来了，在网上查找发现两种情况：

    1、运用Filte包不齐全
 2、第二种情况：

google里搜索Error filterStart里有个文章说tomcat里的bug,没有实现javax.servlet.Filter的Filter会报这样的错误：

看来tomcat在启动就初始化Filter实例了，可能是Filter里的啥东东执行出错导致可能，看看Filter的init里用到一句

mServ = (ModuleService)WebUtils.getApplicationContext(config.getServletContext()).getBean("moduleService");

是最可能发生错误了，因为这里用到了spring的org.springframework.web.context.ContextLoaderServlet，如果启动这时还没有建立该servlet实例，务必导致获取失败，抛出错误。先屏蔽一下这句话，果真启动正常了，修改一下代码，将init里的这句话丢到了doFilter里面

        if(mServ==null)
            mServ = (ModuleService)WebUtils.getApplicationContext(filterConfig.getServletContext()).getBean("moduleService");

不过Tomcat也真是，解析web.xml的顺序上还是太僵硬了。

我的出错情况：

经仔细推敲查找发现是配置文件struts.xml配置时候action文件名错误

原因：tomcat启动时会通过web.xml文件寻找struts.xml文件。又因struts2.0默认有拦截器的，所以如果这里的有错误信息，就会报Filter错误，很容易引起误导。

刚开始以为是配置问题，后来把所有的jar包导进去，ok了，经查看少包：rrife-continuations.jar
