Eclipse: Tomcat Server ports are already in use

Working with Eclipse IDE, I use Apache Tomcat to hosting applications on Windows. I forgot what I've done when encounter this problem:"Several ports required by Tomcat  are already in use."

Yes, there must be another process using the ports. Apache Tomcat service was not started on Windows Sevices. Also I've checked using web browser http://localhost:8080/ and I got status report 404 message. Yes Apache Tomcat still run and listening on 8080. I suspect that the problem arises because using Eclipse incorrectly.

To list the listening port using: C:>NETSTAT -na | find "LISTENING"

Yes they were running. The running process could not stopped when exit from Eclipse IDE. Oh yeah, i've terminated the Eclipse IDE abnormally using End Process on Task Manager. So I have to kill the PID:

C:>TASKLIST /FI "PID eq 5740"
C:>TASKKILL /F PID 5740

then re run the server from Eclipse environment.

It works.
