有个问题在网上各种找解决方案无果。错误：
HTTP Status 404 - /abc/type Status reportmessage /abc/description The requested resource is not available.Apache Tomcat/7.0.42
abc是在webapps目录下的一个目录，我在里面放了一个hello.jsp文件，tomcat启动后我访问localhost:8080/manager/html
然后再点击abc这个目录就报了这个错误。
我把hello.jsp放在ROOT目录下可以正常打开Tomcat Version JVM Version
Apache Tomcat/7.0.42 1.7.0_25-b17web.xml文件的内容：

楼上有说是我jsp文件路径不对。我是看韩顺平老师的视频学的servlet和jsp。我的jsp路径和他的jsp路径完全一致，他成功了为何我不成功。。这是我想不通的地方。
你的工程名叫abc,不代表访问tomcat的时候你的路径名为abc
你这里肯定是填了别的了，所以访问不到资源。你看看你这里的路径是什么
