Well I was believing it was the answer on the second one. Well I already do
this but I doesn't work like I expected. I'll try to retest this feature
soon.

What I mean is that when you take the MQSeries routing model when you send a
message to a remote queue, this message is directly forwarded from the
transmit queue - this is your private queue in fact - to the final
destination queue even if there is no consumer on this final destination
queue : that's what I call routing on the PUT...
On ActiveMQ - and so on Qpid if I understand well - the routing is on the
GET. The message stay in the transmit queue and will be forwarded until
there is a request on the final destination. For me this model raises some
problems - which are maybe not a problems but that's why I ask :) :
for example I have a network of broker with N node. Imagine that at time T
there is one message delivered at different time on each private queue
corresponding to one {exchange, routing key} and that at this time you do
not have a consumer started on a queue corresponding to this {exchange,
routing key}. Naturally we assume there is no network problem. Now at time
T+1 you start your consumer :
1) How will the FIFO ordering of the global delivery assumed ? I mean, how
can QPid assure the global FIFO ordering - I.E : that message mX delivered
on the private queue of the node X before message mY delivered on private
queue of node Y will be consumed before mY ?
2) for one {exchange, routing key} you can have severals destination queue
as I understood. Imagine you have 2 finals destination queues (Q1, Q2) for
our private queue corresponding to {exchange, routing key}. Our consumer
only consume Q1. Will Q2 received it's messages ? Or will the messages stay
on the private queue until there is a consumer on queue Q2 ?
I've others question about the routing model on QPID, but I prefer to test
this two cases as soon as possible before. Anyway I'll be very interested
about what you think.

I'm not sure to understand. Do you mean that we can't have more than one
producer for one consumer ?
Thanks for all
