Broker does the work. This is standard in JMS 1.1. If you want to see exactly what is happening, use snoop or wireshark between client and broker.
>From the JMS 1.1 standard, chapter 3.8 "Message Selection": "JMS provides a facility that allows clients to delegate message selection to their JMS Provider" From: 3.8.1 "Message Selector": A JMS message selector allows a client to specify, by message header, the messages it's interested in. *Only messages whose headers and properties match the selector are delivered*." We are then sent to look at 5.8 "QueueReceiver"for the meaning of "not delivered"... unselected messages remain on the queue, following the principle that each Q message is consumed exactly once.
