// Note: We currently have no requirement to provide a managed pooling implementation of javax.sql.XADataSource.
/**
This implementation of javax.sql.DataSource can be used to produce Connection objects that will automatically participate in connection pooling, and are managed by the Toolbox's built-in connection pooling manager.
A DataSource is a factory for connections to the physical data source that this DataSource object represents.
An alternative to the DriverManager facility, a DataSource object is the preferred means of getting a connection.
An object that implements the DataSource interface will typically be registered with a naming service based on the
Java Naming and Directory (JNDI) API.
A DataSource object has properties that can be modified when necessary. For example, if the data source is moved to a
different system, the property for the system can be changed. The benefit is that because the data source's properties
can be changed, any code accessing that data source does not need to be changed.
A driver that is accessed via a DataSource object does not register itself with the DriverManager. Rather, a DataSource o
bject is retrieved though a lookup operation and then used to create a Connection object. With a basic implementation,
the connection obtained through a DataSource object is identical to a connection obtained through the DriverManager facility.
Caution: To avoid the pitfalls of "double-managed" pools, do not use this class in conjunction with a separate
connection pool manager, such as that available in WebSphere. When a separate pool manager is provided,
use {@link AS400JDBCDataSource AS400JDBCDataSource} instead.
