Yes, you can change the default port number (8080) on the file
%CATALINA_HOME%\conf\server.xml , search the

A usual combination in Win/NT Systems is the IIS (Running in another port)as the front to the web (working together with DNS server to provide names
and security:
https://www.myapplication.mycompany.com ), and internally the IIS is pointing to a local application in another port:
http://localhost:8040/myapplication
