In fact, this is your mysql driver package version is too low, I use the mysql-connector-java-3.1.12-bin.jar, version too old to cause a problem;

Solution: change a little higher version, such as mysql-connector-java-5.1.47-bin.jar, in lib package will replace the low version, and then restart the server on it!
