Derby only provides an implementation of ConnectionPoolDataSource, it
does not provide a connection pool manager. An application server such
as WebSphere or Geronimo provides a connection pool manager which
handles the actual pooling on top of Derby's ConnectionPoolDataSource.
Thus the application server documents how to configure the pool.

Derby follows the model described in Chapter 11 of JDBC 3.0 spec and
shown well in figure 11.1.
