Server Tomcat v7.0 Server at localhost was unable to start within 101 seconds. If the server requires more time, try increasing the timeout in the server edit
I got the solution for your requirement.
I'm also getting the same error in my eclipse Luna.
Go to Windows option -> select preference.
Than Select General -> Network Connection.
Than select the Active Provider as Manual.
Then restart the tomcat and run. It will work.
Hope it will help you.
