新建dynamic web project ,就创建一个index.jsp 然后点那个绿色三角
跳出对话框报错： Several ports (8081, 8009) required by web1sq at localhost are already in use. The server may already
be running in another process, or a system process may be using the port. To start this server you will need
to stop the other process or change the port number(s).直接通过网页打开，提示：
HTTP Status 404 - /web1/index.jsp--------------------------------------------------------------------------------
type Status report
message /web1/index.jsp
description The requested resource (/web1/index.jsp) is not available.应该是占了端口，也基本肯定是tomcat的原因，大家帮我想下怎么解决，谢谢
Tips:
网页结构是正确的并且有web.xml的，tomcat的8080改成了8081
http://localhost:8081/ tomcat的网页是可以打开的 tomcat安装的时候必须是默认路径 如果改成其他路径（比如d:\mytomcat）是装不上去的，但环境变量肯定是对的在C:\Program Files\Apache Software Foundation\Tomcat 7.0\work\Catalina\localhost下面没有web1这个目录
