Closing a Message Group

+ +

You generally don't need to close a message group; just keep using it. However if you really do want to close a group you can add a zero sequence number.

+ +
+
message.setIntProperty("JMSXGroupSeq", 0);
+
+ +

This then closes the message group so if another message is sent in the future with the same message group ID it will be reassigned to a new consumer.

+

Example

Lets say we are doing some kind of order matching system where people are buying and selling things (stocks, shares, placing online bets, whatever).
