Re: [ebxmlms-develop] How to tell is

[Bob K. <py...@ce...>]

I think the case is that receiver may not know whether the ack is
received successful. The logic on reliable messaging is that if the
receiver receive a message with ackRequested, he MUST send back the ack.
to the sender. Whether the ack. will successfully deliver to the sender
is unknown, but if the sender doesn't get the ack, it will resend the
message again. Therefore, we cannot store whether the ack is
successfully received by the sender in receiver side.

The STATE_RECEIVED_ACKNOWLEDGED is used for state on a sent message
which an ack. is received.
