MyEclipse_IDE Problem Port already in use:1098 JVM_Bind exception

Hi all,
I am using MyEclipse IDE for developing a jsp application.I am using Tomcat server.Server starts correctly.But when i try to run the application i get following error in consol window.
Any idea?

Another application already has port 1098 open. You will have to either stop that app, change that other app to use another port, or change Tomcat to use another port.

What OS are you using? If Windows or Linux you can use netstat to determine which app is using port 1098. If Windows you will be better off using TCPView from sysinternals.

Thanks for your reply.
I am using Window XP professional.
I downloaded tcpview and found javaw.exe running on port 1098.I ended that process.
Then again tried to run my project. Then i got the following message on console.but application still is not running.
