/**
* <p>
* This package provides support for pooling of ManagedConnections. A managed
* connection is responsible for managing a database connection in a
* transactional environment (typically called <em>Container Managed</em>).
* A managed connection operates like any other connection when no global
* transaction (a.k.a. XA transaction or JTA Transaction) is in progress.
* When a global transaction is active a single physical connection to the
* database is used by all ManagedConnections accessed in the scope of the
* transaction. Connection sharing means that all data access during a
* transaction has a consistent view of the database. When the global
* transaction is committed or rolled back the enlisted connections are
* committed or rolled back.
* </p>
* <p>
* This package supports full XADataSources and non-XA data sources using
* local transaction semantics. non-XA data sources commit and rollback as
* part of the transaction but are not recoverable in the case of an error
* because they do not implement the two-phase commit protocol.
* </p>
