[Solved]-Eclipse Tomcat server does not start-eclipse

this can happen if already an instance of tomcat server is running on the port(default is 8080). kindly run below command in command prompt

netstat -ano

to list down the list of process and the port they acquire that are running currently and see if there a process running on the port that your tomcat server is trying to acquire.

if yes, kill it and run the server again

had the same problem with tomcat 7 (liferay server), seems to be a compatibility bug in eclipse, i had to change to a lower version of eclipse.

i don't know how this worked, but merely restarting the pc and cleaning eclipse's tomcat server solved this issue.

also, if at any point of time there is a security alert asking permission to allow java to access public or private networks, check all the boxes.
