Though
"com.mysql.jdbc.Driver" is the driver url, i would suggest you to just check the version of the driver against the version of your MySQL database.
If both of them are incompatible, then you would still get an error!
You just refer the same in the website.
For example, this
link lists the latest version of ConnectorJ (the
JDBC driver for MySQL) here. You can choose the appropriate the version in the box on the left side.
