When trying to create the Data Source -> selecting JDBC -> Manage Drivers -> adding mysql-connector-java-5.1.48-bin.jar to the list, but the Driver Class dropdown list stays empty !
In my logs, I get warnings like :
Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
