Glassfish V3 … the Port is NOT in use!
If you’re trying to start Glassfish (any version) and it complains that it can not start the server or create a domain because the port is in use, don’t check the port, check your hosts file. Glassfish gives this error if the hostname does not resolve (including for localhost).
Or maybe it’s really in use or blocked. But probably not. You checked that first, right?
