之前一直有用，今天添加了一些东西就挂了，删掉之后还是无法启动tomcat服务器
MyEclipse报错：

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）

希望各位看看，可能是 jar包，struts.xml配置 出了问题 可是就是找不到它的症结，不知道从哪里下手。
------解决思路----------------------
<filter>
<filter-name>struts</filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
</filter>
这个就是过滤器，我觉得应该是struts的包问题吧，你这是struts2.0的包吗
