while executing spring boot soap example keep getting error like below
The Tomcat connector configured to listen on port 8081 failed to start. The port may already be in use or the connector may be misconfigured.
Verify the connector's configuration, identify and stop any process that's listening on port 8081, or configure this application to listen on another port.
I tried 8080 as well in application.properties even that did not work
how to find what ports are free on my windows 10 laptop to use that ?
