The JMS API defines ten levels of priority value, with 0 as the lowest priority and 9 as the highest. In addition, clients should consider priorities 0-4 as gradations of normal priority and priorities 5-9 as gradations of expedited priority.
See the WebLogic documentation for information on how to configure destinations so that they sort in priority order.
Important: When a message is sent, this field is ignored. After completion of the
Publish method, the field holds the priority value set by the producer.
|MessageException||if JMS fails to get the message priority due to some internal error.|
