使用Eclipse编写JSP调试的时候出现错误，错误提示是Several ports (8005, 80, 8009) required by Tomcat v6.0 Server 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).，电脑上安装了TOMCAT，根据上面的提示说是端口已被使用，但我重新改TOMCAT使用的端口后，还是出现这种错误该怎么解决？
可能是因为你的eclipse 没有正常关闭 tomcat的进程还在导致的 如果端口改不好的话 可以打开任务管理器到进程中把java.exe关掉就可以了
