> Currently when org.apache.commons.dbcp2.BasicDataSource is directly instantiated (e.g.
in an IoC environment), the only way to set the type of java.sql.Driver that is should use
is by passing in a String classname which is then passed to DriverManager.  The downside to
this is that it requires the DataSource and the Driver to be in the same classloader.  In
practice many times the Driver is in the application classloader while the DataSource is in
the container classloader meaning that other than packaging a Tomcat JAR in your application
you cannot use the DataSource directly.
> It'd be great to have a way to pass the actual instance of Driver to the DataSource and
have it use that instead of going to DriverManager to find it.  This would enable standard
classloader inheritance to work properly and allow the non-adjacent packaging of the Driver
and DataSource.
> An example of this style of configuration can be found in Spring's SimpleDriverDataSource[1].
