public class ActiveMQQueueSender extends ActiveMQMessageProducer implements QueueSender
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.

Typically, a message producer is assigned a queue at creation time; however, the JMS API also supports unidentified message producers, which require that the queue be supplied every time a message is sent.
