Standard JMS Properties

JMS defines a set of standard properties. The property names starting with the string ‘JMSX’ are reserved for standard JMS properties. The providers need not implement all the standard JMS properties and JMS clients can find the supported JMSX properties using the connection's metadata. The providers set most of the JMSX properties and the JMS clients set a couple of them. The table below explains the different JMS standard properties:

Property	Type	Set by	Description
JMSXUserID	String	Provider	Identifies the user who sent the message.
JMSXAppID	String	Provider	Identifies the application that sent the message.
JMSXDeliveryCount	int	Provider	Indicates the number of times the message has been delivered.
JMSXGroupID	String	Client	Identifies a custom message group.
JMSXGroupSeq	int	Client	Identifies the sequence number of the message in the current group.
JMSXProducerTXID	String	Provider	Identifies the transaction in which the message was produced.
JMSXConsumerTXID	String	Provider	Identifies the transaction in which the message was consumed.
JMSXRcvTimestamp	long	Provider	Identifies the time at which the message was delivered to the client. The time is defined as the number of milliseconds since the 1st of January 1970.
