У меня была похожая проблема, но разница заключалась в том, что я запускал свое JavaApp не из localhost, а с удаленного компьютера. Итак, у меня получилось что-то вроде java.sql.SQLException: Access denied for user 'root'@'a.remote.ip.adress' (using password: YES) Чтобы решить эту проблему, вы можете просто войти в phpMyAdmin, перейти на Users, нажать add user и ввести хост, с которого вы хотите запустить свое JavaApp (или выбрать Any Host)
