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.
