用struts2+jsp做个网站，到了网站制作后期时，启动tomcat竟然无法启动，挂了。之前一直有用可是今天添加了一些东西就挂了，删除之后还是无法启动tomcat服务器。
下面是报错的代码：

SEVERE: Error filterStart
四月 09, 2015 9:23:59 上午 org.apache.catalina.core.StandardContext startInternal
SEVERE: Context [/MusicWeb] startup failed due to previous errors 导入的jar包：（网上说 少了jar包或是多了jar包 ，之前都有用，后来也适当改了一些jar包还是没用）
web.xml的配置:(提示说是过滤器Filter的问题,可是我没用到什么过滤器呀）
struts
org.apache.struts2.dispatcher.FilterDispatcher
struts
/*
login.jsp
404
/error.jsp
因为觉得要么是 jar包不一致或是冲突 ，struts.xml配置文件出了问题，web.xml配置文件出了问题，围绕这三个方面整了好久，都没有无法启动。
谁知第二天打开电脑，重启tomcat服务器 竟然没有挂，工程也可以部署，一切都正常。（注：原来添加的内容删除了）
然后我又要接着做昨天的东西，终于发现服务器报上面错误的原因了，在我的struts.xml配置文件中
另一个Action的方法 如果这样写就会出现上面的错误
但是如果
把/error.jsp 就不会报错 ，并且报错之后，改回来了服务器还是无法启动。
出现问题的原因找到了，但是为什么出现以及如何解决还不清楚，希望有出错的可以一起探讨下补充下出错时的日志文件：
