Answer 1

javax.servlet.ServletContext.getContextPath(String path)，是无此方法的错误，很可能是版本问题，你用的那三个jar包 ，serlvet是那个版本的

Answer 2

网上查看你这个错误的话说
页面的action和serlevt里面的path(即是路径)没对应上，你检查下你页面有没写错什么
这个是在项目发布就报错的么...把你jsp贴上来看看

追问

项目发布是没问题，主要是只要有这3个JAR包项目就无法启动，删除这3个就没问题，我没有Servlet就用了JSP action 没问题

追答

检查下几个包的版本是不有什么问题阿..还没遇到这种问题..

Answer 3

jar名称和配置发上来看看，肯定是空格或者路径的问题

追问

不是那 问题，我把我同学的配置文件复制了一份还不行，没有那3个包 JSTL没办法用，有那个3个包项目就无法启动，真纠结！！！！！！！！！
