Common JMS Properties and Headers
JMS properties comprise message headers and message properties. MessageHeader properties are set by the JMS client sending the message. You can view these after the message is received. You can also set MessageProperties on the outgoing messages on the Input tab of the activity that sends messages.
Message Headers
The following table describes the messages headers.
| MessageHeaders Property | Datatype | Description |
|---|---|---|
| JMSDestination | string | The destination where the message is sent. |
| JMSReplyTo | string | The JMS destination where the reply message should be sent. |
| JMSDeliveryMode | string | The delivery mode of the message. Can be one of the following:
|
| JMSMessageID | string | The unique ID of the message. |
| JMSTimestamp | long | The time a message was handed off to a JMS provider to be sent. The time is expressed as the amount of time, in milliseconds, since midnight, January 1, 1970, UTC. |
| JMSExpiration | long | The expiration time of the message. The time is expressed as the amount of time, in milliseconds since midnight, January 1, 1970, UTC. If set to 0, the message does not expire. |
| JMSRedelivered | boolean | Typically this item is set when the JMS provider has delivered the message at least once before. |
| JMSPriority | integer | The priority of the message. Priority is a value from 0-8. Higher numbers signify a higher priority (that is, 8 is a higher priority than 7). |
| JMSCorrelationID | string | This ID is used to link a response message with its related request message. This is usually the message ID of a request message when this field is found in a reply message. |
| JMSType | string | The JMS provider-supplied string to describe the type of the message. Some JMS providers use this property to define messages in the provider’s repository.
For more information about the use of this field, see the JMS provider documentation. |
