Interface QueueSender
- All Superinterfaces:
AutoCloseable
,MessageProducer
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.

send
Sends a message to a queue for an unidentified message producer. Uses theQueueSender
's default delivery mode, priority, and time to live.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.
- Parameters:
queue
- the queue to send this message tomessage
- the message to send- Throws:
JMSException
- if the JMS provider fails to send the message due to some internal error.MessageFormatException
- if an invalid message is specified.InvalidDestinationException
- if a client uses this method with an invalid queue.- See Also:

- Parameters:
queue
- the queue to send this message tomessage
- the message to senddeliveryMode
- the delivery mode to usepriority
- the priority for this messagetimeToLive
- the message's lifetime (in milliseconds)- Throws:
JMSException
