Answer 1

根据你的描述
首先确认tomcat是否启动成功：在webapps文件夹下寻找看是否有自带的项目（默认情况下是会有项目的），比如我文件夹下有个manager,就访问：
localhost:8080/manager即可弹出一个密码输入框，就表明tomcat启动成功。
如果没有成功，查看日志文件再到csdn上贴出。
如果成功，就把你的项目放到webapps文件夹下运行tomcat即可。
---------------------------------------------------------如果仍然报以上的错误
有可能是项目重复添加catalina.jar包，在项目的lib文件夹下找看看是不是多放了这个。凡是和tomcat相关的包在项目中都不要出现。
