/** A client uses a QueueSender object to send messages to a queue.
*
* Normally, the Queue is specified when a
* QueueSender is created. In this case, an attempt to use
* the send methods for an unidentified
* QueueSender will throw a
* java.lang.UnsupportedOperationException.
*
*
If the QueueSender is created with an unidentified
* Queue, an attempt to use the send methods that
* assume that the Queue has been identified will throw a
* java.lang.UnsupportedOperationException.
*
*
During the execution of its send method, a message
* must not be changed by other threads within the client.
* If the message is modified, the result of the send is
* undefined.
*
*
After sending a message, a client may retain and modify it
* without affecting the message that has been sent. The same message
* object may be sent multiple times.
*
*
The following message headers are set as part of sending a
* message: JMSDestination, JMSDeliveryMode,
* JMSExpiration, JMSPriority,
* JMSMessageID and JMSTimeStamp.
* When the message is sent, the values of these headers are ignored.
* After the completion of the send, the headers hold the values
* specified by the method sending the message. It is possible for the
* send method not to set JMSMessageID and
* JMSTimeStamp if the
* setting of these headers is explicitly disabled by the
* MessageProducer.setDisableMessageID or
* MessageProducer.setDisableMessageTimestamp method.
*
*
Creating a MessageProducer provides the same features as
* creating a QueueSender. A MessageProducer object is
* recommended when creating new code. The QueueSender is
* provided to support existing code.
