Host name: localhost
Port: 3306
Database name: Test

After the experiment, found that the cause of the error is MySQL version of the JDBC package is selected wrong, the use of Mysql-connector-java-5.1.30-bin.jar is no problem

By the right: newly created repository default "account: admin Password: admin" "Account: Guest Password: Guest"
