struts 问题

menglianjing

在web.xml写好了struts的部分，启动时出现Error deploying web application directory ROOT java.lang.NoClassDefFoundError:javax/servlet/http/HttpServlet
这是怎么会事？还有叫查什么网站或者叫翻资料的回答不必了，如果这样我想我没必要来此发问，谢谢。
我的web.xml

java.lang.NoClassDefFoundError:javax/servlet/http/HttpServlet
tomcat找不到servlet.jar文件

menglianjing

这个我知道，但是怎么解决呢？Thanks

fangshun

tomcat居然找不到servlet.jar???

menglianjing

那我有什么办法，我也不想的。只是它就是这样，怎么解决？

fangshun

是不是你把servlet.jar从common/lib中删除了???

menglianjing

绝对没有

hantsy

tomcat webapps 目录下的ROOT目录放了什么东东

hantsy

请看下webapps 下xml文件，和tomcat/conf/server.xml文件，这觉得应该是这哪个文件配置有问题。。。有没有手动修改过

menglianjing

没有修改过，只是在ROOT下建立了我自己的目录
