Answer / qim2010
An application simply uses the DataSource.getConnection
method to get the pooled connection and uses it the same way
it uses any Connection object.
The classes and interfaces used for connection pooling are:
ConnectionPoolDataSource
PooledConnection
ConnectionEvent
ConnectionEventListener
The connection pool manager, a facility in the middle tier
of a three-tier architecture, uses these classes and
interfaces behind the scenes. When a
ConnectionPoolDataSource object is called on to create a
PooledConnection object, the connection pool manager will
register as a ConnectionEventListener object with the new
PooledConnection object. When the connection is closed or
there is an error, the connection pool manager (being a
listener) gets a notification that includes a
ConnectionEvent object.
