| * A client uses a <CODE>QueueSender</CODE> object to send messages to a |
| * queue. <p/> |
| * <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/> |
| * <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/> |
| * <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/> |
| * <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/> |
| * <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/> |
| * <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. |
