I rote this 2 pages, but I don't see anything about my exemple. Shure I don't understand well.

What I said is, in other words :

forceqQueuing and PtP (destination QoS)
work fine in Asynchronous mode ( implements I_Callback )
but it seems not work in synchronous mode ( connection.get() ).

Is that you understood ?
So it's not possible ?

Is there a guide line for developping this need ?
Because I really need it, so if it's not to hard , I can do it.
But I need some help like guide line and architecture overview.
