Tomcat：Several ports are already in use问题

Several ports (8005, 8080, 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).

在eclipse非正常关闭或者没关闭掉tomcat情况下，虽然eclipse关掉了，但是Tomcat服务器没有关。若重新使用eclipse会出现上述错误。这种状况解决方法把占用的端口关掉就可以了。目前我没找到能关闭端口的命令行工具。不过可以使用Microsoft的TcpView.zip 来关掉占用的端口，下载地址：http://technet.microsoft.com/en-us/sysinternals/bb897437.aspx

tomcat    oracle  占用8080端口

Program Files\Apache Software Foundation\Tomcat 6.0\conf\server.xml

1、修改端口为8000

<Connector port="8000" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" />

2、eclipse重新加载tomcat
