You can decide to not acknowledge. But then you need some way expire the messages off the broker sooner or later.
>From the JMS 1.1 spec: "JMS retains a record of this durable subscription and insures that all messages from the Topic’s publishers are retained until either they are acknowledged by this durable subscriber or they have expired." 6.12 "Recovery and Redelivery" defines the standard behaviour in this area. You should understand that choosing to never acknowledge a message, while possible, is not part of the pub/sub paradigm. ----- Michael Hayes B.Sc. (NUI), M.Sc.
