If you want to dynamically load a datasource try something like:
Class dsClass = Class.forName("datasource.class.name.here");
javax.sql.DataSource ds = (javax.sql.DataSource)dsClass.newInstance();
then use reflection to configure the datasource (see the JDBC spec for
standardized methods). The same approach works for ConnectionPoolDataSource.
