严重: Error loading WebappClassLoader
问题描述：
本人在新建strut1项目的时候，tomcat加载项目的时候出现了这样的问题；
我把这个项目设置成tomcat的根项目，也就是通过http://localhost:8080直接这样就能访问的形式，才出现这样的问题。
请问高手，

[解决办法]
java.lang.ClassNotFoundException: org.apache.struts.action.ActionServlet
少了struts.jar这个包吧？ 或者是struts包的其他依赖jar
[解决办法]
java.lang.ClassNotFoundException: org.apache.struts.action.ActionServlet
确实少了这个jar包，你把它放到tomcat/shared/lib 目录下面
如果是tomcat 6.x 那放到 tomcat/lib 下面
[解决办法]
恩，支持，struts项目里没有把struts应用到的包加入到项目中去.在项目中，add struts libraies...就可以了
[解决办法]
楼主，我解决了
关掉myeclipse，把原来的tomcat换掉，如果是安装版的就卸载，重新放一个tomcat，启动myeclipse，配置tomcat，部署，再启动tomcat，一切OK
