>From JMS Spec on Message setPriority: "Sets the priority level for this message. JMS providers set this field when a message is sent. This method can be used to change the value for a message that has been received." So you can see this method is only applicable after you receive a message, not when its sent. The producer is the one that sets the priority on each Message when the send method is called. >From MessageProducer JMS API for setPriority "Sets the producer's default priority. The JMS API defines ten levels of priority value, with 0 as the lowest priority and 9 as the highest. Clients should consider priorities 0-4 as gradations of normal priority and priorities 5-9 as gradations of expedited priority. Priority is set to 4 by default." Or you can do it on each Message send via the five argument send method in MessageProducer: "public void send(Destination destination, Message message, int deliveryMode, int priority, long timeToLive) throws JMSException Sends a message to a destination for an unidentified message producer, specifying delivery mode, priority and time to live. Typically, a message producer is assigned a destination at creation time; however, the JMS API also supports unidentified message producers, which require that the destination be supplied every time a message is sent. Parameters: destination - the destination to send this message to message - the message to send deliveryMode - the delivery mode to use priority - the priority for this message timeToLive - the message's lifetime (in milliseconds) " Regards -- Tim Bish ------------ FuseSource Email: tim.b...@fusesource.com Web: http://fusesource.com Twitter: tabish121 Blog: http://timbish.blogspot.com/
