JMSXAppID
Java Message Service
This property is a String that is set automatically by the JMS provider when the
message is sent. Some JMS providers can assign an identifier to a specific JMS
application, which is a set of consumers and subscribers that communicate using a
set of destinations.
JMSXProducerTXID and JMSXConsumerTXID
Messages can be produced and consumed within a transaction. Every transaction in a
system has a unique identity that can be obtained from the producer or consumer
using these properties. The JMSXProducerTXID is set by the JMS provider when the
message is sent, and the JMSXConsumerTXID is set by the JMS provider when the
message is received.
JMSXRcvTimestamp
This property is a primitive long value that is set automatically by the JMS provider
when the message is received. It represents the UTC time (see UTC in Appendix B)
that the message was received by the consumer.
JMSXDeliveryCount
JMSXState
This property is an int that is set automatically by the JMS provider when the
message is received. If a message is not properly acknowledged by a consumer it
may be redelivered. This property keeps a tally of the number of times the message
server attempts to deliver the message to that particular consumer.
This property is an int that is set automatically by the JMS provider. The property is
for use by repositories and JMS provider tools and is not available to either the
consumer or producer - as a developer, you will never have access to this property.
The property provides a standard way for a JMS provider to annotate the state of a
message. States can be one of the following: 1 (waiting), 2 (ready), 3 (expired), or 4
(retained). This property can be safely ignored by most JMS developers, but an
explanation of its purpose is provided for completeness.
The JMS-defined properties that are assigned when the message is received
(JMSXConsumerTXID, JMSXRcvTimestamp, and JMSXDeliveryCount) are not available to the
message's producer, but only available to the message consumer.
C.7.2 Group JMS-Defined Properties
While the bulk of JMSX properties are optional, the group properties are not optional; they
must be supported by the JMS provider. The group properties allow a JMS client to group
messages together and assign each message in the group with a sequence ID. Here are the
group properties:
