在电脑上找到这个路径:D:\jakarta-tomcat-6\conf\Catalina,将localhost目录直接删除掉,再一运行,就没事了! 因为配置文件中配置了启动程序，而webapps文件夹下却没有此应用程序，所以出现了上述错误。

========================================================

1.该项目的War文件从***\apache-tomcat-6.0.16\webapps 移出；

2.该项目的某些配置从 ***apache-tomcat-6.0.16\work\Catalina\localhost 移除；

3.该项目的配置文件，目录： ***\apache-tomcat-6.0.16\conf\Catalina\localhost移除。

前2步，我想很多人都知道，做了1，2，是不够的，必须把第三步也做了才行
