Windows first-time use of demo

How does windows know to listen on port 8080 for the demo?
I ran start.bat in c:\openhab to launch the server
but netstat -a shows nothing listening on port 8080

when I browse using the following url:
http://localhost:8080/openhab.app?sitemap=demo
…the browser tells me:
“Google Chrome’s connection attempt to localhost was rejected. The website may be down, or your network may not be properly configured.”

Totally new to openhab so would appreciate any advice you can give. Thanks

Did you start the batch from cmd-line?

Looks like openHAB is not actually running. Loke @Udo_Hartmann suggests, run the start.bat from the command line and look for errors. If you see no errors then try again. It might be your Windows firewall is blocking the requests.
