/** A QueueSession object provides methods for creating
* QueueReceiver, QueueSender,
* QueueBrowser, and TemporaryQueue objects.
*
* If there are messages that have been received but not acknowledged
* when a QueueSession terminates, these messages will be retained
* and redelivered when a consumer next accesses the queue.
*
*
A QueueSession is used for creating Point-to-Point specific
* objects. In general, use the Session object.
* The QueueSession is used to support
* existing code. Using the Session object simplifies the
* programming model, and allows transactions to be used across the two
* messaging domains.
*
*
A QueueSession cannot be used to create objects specific to the
* publish/subscribe domain. The following methods inherit from
* Session, but must throw an
* IllegalStateException
* if they are used from QueueSession:
*
* createDurableSubscriber
* createTemporaryTopic
* createTopic
* unsubscribe
