On Windows 7 I downloaded the \'netbeans-8.0.1-javaee-windows.exe\' installer from this site https://netbeans.org/downloads/. The installer installs GlassFish 4.1, Java 1.8.
I have the same problem. Mine is caused by a vmware installation. It is vmware worstation v8 on windows 7 and was a default installation.
Running netstat -aon | find ":80" | find "LISTENING" from cmd showed PID of the service causing the problem, this related to vmware. Going to services, I manually stopped all of the running vmware services (did not change their start up type, just a manual stop - I want them to work again after the next reboot) I could immediately test my webservice, glassfish 4 started as it should.
Hope it helps
