<div class="block">A client uses a <code>QueueSender</code> object to send messages to a queue.
<p>
Normally, the <code>Queue</code> is specified when a <code>QueueSender</code> is created. In this case, an attempt to use the
<code>send</code> methods for an unidentified <code>QueueSender</code> will throw a
<code>java.lang.UnsupportedOperationException</code>.
<p>
If the <code>QueueSender</code> is created with an unidentified <code>Queue</code>, an attempt to use the <code>send</code> methods
that assume that the <code>Queue</code> has been identified will throw a <code>java.lang.UnsupportedOperationException</code>.
<p>
During the execution of its <code>send</code> method, a message must not be changed by other threads within the client. If
the message is modified, the result of the <code>send</code> is undefined.
<p>
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.
<p>
The following message headers are set as part of sending a message: <code>JMSDestination</code>, <code>JMSDeliveryMode</code>,
<code>JMSExpiration</code>, <code>JMSPriority</code>, <code>JMSMessageID</code> and <code>JMSTimeStamp</code>. When the message is sent,
the values of these headers are ignored. After the completion of the <code>send</code>, the headers hold the values
specified by the method sending the message. It is possible for the <code>send</code> method not to set
<code>JMSMessageID</code> and <code>JMSTimeStamp</code> if the setting of these headers is explicitly disabled by the
<code>MessageProducer.setDisableMessageID</code> or <code>MessageProducer.setDisableMessageTimestamp</code> method.
<p>
Creating a <code>MessageProducer</code> provides the same features as creating a <code>QueueSender</code>. A
<code>MessageProducer</code> object is recommended when creating new code. The <code>QueueSender</code> is provided to support
existing code.</div>
