These are the main parts of a EMS message.
Message Headers :
- JMSDestination
Destination to which message is sent.
- JMSDeliveryMode
Persistent, Non-persistent or Reliable.
Default is Persistent.
- JMSExpiration
Length of time the message will live before expiry.
If the server expiration property is set for a destination, it will override the JMSExpirationvalue set by the message producer.
- JMSPriority
Priority of the message. Larger numbers indicate higher priority.
- JMSMessageID
Unique identifier for a message.
- JMSTimeStamp
Timestamp of the time when the message was handed off to a provider to send. Message may actually be sent later than this timestamp.
- JMSCorrelationID
This ID can be used to link messages, such as linking a response message to a request message.
- JMSReplyTo
A destination to which a message reply should be sent.
- JMSRedelivered
If this field is set, it is possible that the message has been delivered to the client earlier, but not acknowledged at that time.
