/** A QueueConnection object is an active connection to a
* point-to-point JMS provider. A client uses a QueueConnection
* object to create one or more QueueSession objects
* for producing and consuming messages.
*
*A QueueConnection can be used to create a
* QueueSession, from which specialized queue-related objects
* can be created.
* A more general, and recommended, approach is to use the
* Connection object.
*
*
*
The QueueConnection object
* should be used to support existing code that has already used it.
*
*
A QueueConnection cannot be used to create objects
* specific to the publish/subscribe domain. The
* createDurableConnectionConsumer method inherits
* from Connection, but must throw an
* IllegalStateException
* if used from QueueConnection.
