public class SharedPoolDataSource extends InstanceKeyDataSource
 A pooling DataSource appropriate for deployment within J2EE environment. There are many configuration
 options, most of which are defined in the parent class. All users (based on user name) share a single maximum number
 of Connections in this data source.
 
 User passwords can be changed without re-initializing the data source. When a
 getConnection(user name, password) request is processed with a password that is different from those
 used to create connections in the pool associated with user name, an attempt is made to create a new
 connection using the supplied password and if this succeeds, idle connections created using the old password are
 destroyed and new connections are created using the new password.
