anonymous wrote : JBossMQ already has redelivery delay/count I know, the specs (and comment in the jboss code) specifically state however that ordered delivery of redelivered messages is not gueranteed. This would be a first addition I think. Bea also does this and mentiones this as a unique selling point. A second addition would be a kind of windowing mechanism, which could be achieved partly by using a session and not realy acknowledge e.g. message 1...5 but these have to be kept at hand since an ack on message 5 also acks all previous messages in that session (in accordance with the spec)
anonymous wrote : There is currently no mechanism to override the spec defined order of | priority/arrival sequence, but I would accept a patch that allowed a | Comparator to be defined per Queue/Topic. You mean a comparator for the TreeSet that is used in the BasicQueue? Nice thinking. This could be parameterized so the names of jms headers could be passed to it and used for the sorting. But would it also add the possibility of ordered delivery of redeliverd messages? Probably not, but I did not look in the code yet on that part. Besides that, I have no idea how the TreeSet would be passed this new comparator, let alone a comnfigurable comparator. anonymous wrote : I would doubt this would make it into JMS spec. | JMS is a lowest common denominator spec designed to plug disparate | messaging systems. I know, but it would be a waste of already good functioning code (jms) if it does not fit the new, higler level, specs. The jms specs should (im(ns)ho) be more in line with these.
