Yes,
when a procuder calls send() method, I'd like to intercept
the request, verify number of messages in destination queue,
throw an exception if number of msg, after this last send(),
exceed a predefined limit.
In AMQ 5.3 I can define a memoryLimit for a queue but
there are two "problems".
1) memoryLimit is expressed in Kb/Mb and not in number of messages.
2) I specified a memoryLimit for a queue (1 Mb)
I ran 10 tests where a producer send thousand of messages to the queue.
I verified that number of messages sent to the queue, before a
memoryLimit exception
is thrown by AMQ, differ a lot from one test to another (test1=15885
msg,
test2=29362, test3=32413 then 15861, 24260, 12276, 11692, 24306,
24762, 20269).
I expected a deterministic result.
For this reason I tried to follow the "interceptor way".
Thank you,
Moreno
