Error in running tomcat

Hi

I installed Eclipse 3.1 and Tomcat5.5 in my Windows vista machine. When i tried starting the tomcat server i am getting the following error

"Several ports (8080, 8009) required by Tomcat v5.5 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)."

Can anyone please help me how to solve this issue?

Thanks in advance
