The connection MANAGEMENT contract describes the understanding a J2EE container has with the adapter regarding establishing, pooling, and tearing down connections. The connection management contract ALSO allows listeners created on a connection to respond to events (for instance if the connection becomes lost or experiences an error). Also note that the underlying protocol an adapter uses to connect to an EIS is outside the scope of the JCA specification.

All JCA resource adapters MUST supply two implementations with the adapter. First, a ConnectionFactor provides a VEHICLE for creating connections. Second, the Connection class represents this particular resource adapter's underlying connection.
