把web.xml文件删除，在tomcat中reload不会出错，一把web.xml放进去就报上面的错误。刚开始不知道是web.xml引起的，找了很多种方法没有解决，刚刚再试的时候才发现是web.xml问题。我就觉得奇怪，我导入以前一些没问题的项目，依然报错，我就觉得挺纳闷的，这个web.xml文件本身应该没问题才对的，也还没有写什么东西去。tomcat、MyEclips都重装过，还是有问题。Jar包试过两组，一组是struts 2.1.6，一组是2.2.1的，不过这个问题应该不大，以前都可以用的
这问题整了我好长时间了，求指点求解…………

LZ用了Spring么，没用Spring的话，就把struts.xml中的
<constant name="struts.objectFactory" value="spring" /> 这行注释掉，因为这行表示申明struts.objectFactory为Spring的对象池构建工厂。

把这个struts2-spring-plugin-2.2.1.jar去掉，你都没有用到spring，lib里面还加这个jar干什么。

说明了问题的存在，像楼上说的把那个.jar文件去掉，要么在web.xml文件中配置

<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
