Great tutorial. I'm pasting here the sql script to generate the table used in the video, in case anyone needs it:

create table t_user(
id INTEGER(10) NOT NULL AUTO_INCREMENT,
username VARCHAR(45) NOT NULL,
PRIMARY KEY(id)
) ENGINE=INNODB;

READ ME: for people who will be using glassfish 5 or may be higher in the future, the latest sql Connector/J 8.0.16+ might not work, and when you ping, it might throw Please check the server.log for more details" error!
So a possible solution is to get the old version of the connector - Connector/J 5.1.47 -> This solved my issue! hopefully this will help someone and save some time! :D i love you guys.. good luck programming.. guys
