Modify the default Apache Tomcat port

With the default configuration, Apache Tomcat will listen for requests on port 8080. To use a different port, edit the server.xml file and modify the value specified in the Port directive.

<Connector port="8080" URIEncoding="UTF-8" protocol="HTTP/1.1"
connectionTimeout="20000" redirectPort="8443" />

Restart the Apache Tomcat server for the changes to take effect.
