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.<P><P><DL><DT><B>Version:</B></DT> <DD>1.1 - February 2, 2002</DD><DT><B>Author:</B></DT> <DD>Mark Hapner, Rich Burridge, Kate
