positive.code: To configure a `DriverManagerDataSource`:
  
  . Obtain a connection with `DriverManagerDataSource` as you typically obtain a JDBC
  connection.
  . Specify the fully qualified classname of the JDBC driver so that the
  `DriverManager` can load the driver class.
  . Provide a URL that varies between JDBC
  drivers. (See the documentation for your driver for the correct value.)
  . Provide
  a username and a password to connect to the database.
  
  The following example shows how to
  configure a `DriverManagerDataSource` in Java:

  For an SQL statement that uses the classic `?` placeholders, you pass in a list
  containing an object array with the update values. This object array must have one entry

  defined in the SQL statement.
  
  The following example is the same as the preceding example, except that it uses classic
  JDBC `?` placeholders:

  [source,java,indent=0]
