-- How to check port 80 used ?

netstat -lnp | grep 80

A very basic example to change port 8080 to 80 would be:

1. Stop tomcat

2. Goto Tomcat/conf and take a backup of server.xml file

Open server.xml and you will finde entries like <Connector port="8080" and <Connector executor="8080".

Change port from 8080 to 80 . (Verify that there is no other application listening on port 80)

(this will make tomcat listen on default port which is 80, and hence will not require a port number to mention after midtierserver name)

3.Start tomcat
