tomcat configuring with eclipse

Question

whats the cause of this error while running tomcat 6.0 on eclipse ide helious:

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).

Answer 1

Just read the error message: Tomcat is already running.

Answer 2

Or:

• you have tomcat running in your eclipse workspace (solution: stop the server in eclipse or the eclipse process from your task manager)
• your tomcat is running in the background as a service (solution: kill the tomcat process from your task manager and disable the windows service)
• the ports tomcat use are used by other programs running in the background (solution: kill the processes using these ports from your task manager)
