I just had the same issue with Netbeans 8.2 and trying to connect to mySQL server on a Mac OS machine. The only thing that worked for me was to add the following to the url of the connection string: &serverTimezone=UTC (or if you are connecting via Hibernate.cfg.xml then escape the & as &) Not surprisingly I found the solution on this stack overflow post also:

Fist of all make sure your SQL server is running  Actually I m working on windows and I have installed a nice tool which is called MySQL workbench  you can find it here for almost any platform       Thus I just create a new database to test the connection  let s call it stackoverflow  with one table called user   SET  OLD UNIQUE CHECKS   UNIQUE CHECKS  UNIQUE CHECKS 0  SET  OLD FOREIGN KEY CHECKS   FOREIGN KEY CHECKS  FOREIGN KEY CHECKS 0  SET  OLD SQL MODE   SQL MODE  SQL MODE  TRADITIONAL ALLOW INVALID DATES    DROP SCHEMA IF EXISTS  stackoverflow    CREATE SCHEMA IF NOT EXISTS  stackoverflow  DEFAULT CHARACTER SET utf8 COLLATE utf8 general ci   USE  stackoverflow     -- ----------------------------------------------------- -- Table  stackoverflow   user  -- ----------------------------------------------------- DROP TABLE IF EXISTS  stackoverflow   user     CREATE TABLE IF NOT EXISTS  stackoverflow   user       iduser  INT NOT NULL AUTO INCREMENT     name  VARCHAR 75  NOT NULL     email  VARCHAR 150  NOT NULL    PRIMARY KEY   iduser      UNIQUE INDEX  iduser UNIQUE    iduser  ASC     UNIQUE INDEX  email UNIQUE    email  ASC   ENGINE   InnoDB    SET SQL MODE  OLD SQL MODE  SET FOREIGN KEY CHECKS  OLD FOREIGN KEY CHECKS  SET UNIQUE CHECKS  OLD UNIQUE CHECKS    You can reduce important part to    CREATE SCHEMA IF NOT EXISTS  stackoverflow    CREATE TABLE IF NOT EXISTS  stackoverflow   user           iduser  INT NOT NULL AUTO INCREMENT         name  VARCHAR 75  NOT NULL         email  VARCHAR 150  NOT NULL        PRIMARY KEY   iduser          UNIQUE INDEX  iduser UNIQUE    iduser  ASC         UNIQUE INDEX  email UNIQUE    email  ASC     So now I have my brand new stackoverflow database  Let s connect to it throught Netbeans  Launch netbeans and go to the services panel  Now right click on databases  new connection   Choose MySql connector  they already come packed with netbeans   Then fill in the gaps the data you need  As shown in the picture add the database name and remove from the connection url the optional parameters as l zeroDateTimeBehaviour convertToNull   Use the right user name and password and test the connection    As you can see connection is successful   Click FINISH   You will have your connection successfully working and available under the services

Close NetBeans   Stop MySQL Server   Update MySQL  if available   Start MySQL Server   Open NetBeans    If still doesn t connect  download MySQL Connector J and add mysql-connector-java- version  jar to your classpath and also to your Webserver s lib directory  For instance  Tomcat lib path in XAMPP is C  xampp tomcat lib  Then repeat the steps again
