/**
* A pooling DataSource appropriate for deployment within
* J2EE environment. There are many configuration options, most of which are
* defined in the parent class. This datasource uses individual pools per
* user, and some properties can be set specifically for a given user, if the
* deployment environment can support initialization of mapped properties.
* So for example, a pool of admin or write-access Connections can be
* guaranteed a certain number of connections, separate from a maximum
* set for users with read-only connections.
*
* User passwords can be changed without re-initializing the datasource.
* When a getConnection(username, password) request is processed
* with a password that is different from those used to create connections in
* the pool associated with username, an attempt is made to create
* a new connection using the supplied password and if this succeeds, the
* existing pool is cleared and a new pool is created for connections using the
* new password.
