I received the following error while attempting to execute a Servlet program in Eclipse Mars EE.
'Starting Tomcat v8.0 Sever at localhost' has encountered a problem.
Port 8080 required by Tomcat v8.0 Server at localhost is already in
use. There 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).
