Starting Tomcatv6.0 Server at localhost has encoutered a problem, Port 80 required by Tomcat v6.0 server at localhost already in use. the server may already 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)

While working with tomcat, you might come across this glitch. Here is how to get rid of it easily.

1. Go to server tab in your eclipse. If you cant see it you can have it through window->show view->servers
2. double click on the tomcat server and you will be directed to page for tomcat configuration.
3. On the page you will see list of ports that the current server is using.
4. Change the HTTP/1.1 from 80 – or whatever it is complaining to new one like 9181.
5. what… you’re done… :)

Happy TomCatting.
