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.
Following are the steps that will definitely work:
netstat -aon | find ":8080" | find "LISTENING"
Ctrl+Shift+Esc
)end process
NOTE : If you are running your program for the first time in Netbeans, it takes some time. So don't worry if it takes time.
