Error:Tomcat using ports are already being in usage by some other resources

Hi,
I am a beginner to j2EE.I am am trying to run some jsp pages in my eclipse.
Made the server installed runtime as Tomcat 6.0
But when i am running my jsp page i am getting a message."Serval ports (8005,8080,8009) reuqired by tomcat 6.0 server at localhost are already in use. Server may be running in another process or system may be using those ports. To start the server ,you need stop other process or change the ports".
Btw when i am running this in my browser http://localhost:8080/ . It is showing Apache page.
How to solve this ?
I have reconfigure the tomcat to use other port?
Please suggest me a solution.I am trying let's see!
Regards,
Arjun.

"So, Tomcat was already started outside control of Eclipse. Instead of restarting the computer you can also just stop it using the command console scripts, or by service manager, or by killing the java.exe (or whatever it is called in Mac) in the task manager. "
Thanks problem solved.
