I'm parsing the video and at 8 minutes everything went to dust (starting the derby as I understand it)
GlassFish writes:

[2015- 10-01 08:13:32,479] Artifact SampleApp:war exploded: Error during artifact deployment. See server log for details.
the logs are something like this:
Error connecting to the localhost server on port 1527 with the message Connection refused: connect.
and flashes:
Caused by: org.apache.derby.client.am.DisconnectException: java.net.ConnectException : Error connecting to server localhost on port 1527 with message Connection refused: connect.

...and so on
tried to start derby manually (downloaded, started startNetworkServer, which, by the way, doesn't start).
What could be the problem?
