Re: [ebxmlms-general] Hermes servlet problem

[Patrick Y. <kc...@ce...>]

Hello,

It seems that there are some confusions here, so I have checked and=20
traced the source code once again. And here is my finding:

1. I found that the ACK over SMTP does work. So I apologize for I have=20
given out wrong information to the list before.

2. The reason why the line 464 of MessageServiceHandler.java ignores the=20
returned ACK is that, the returned message would only be processed in=20
the case of SYNC_REPLY. In SMTP case, all messages are sent in=20
asynchronous mode. Therefore, in our mail handling method, we ignore the=20
message generated for synchronous response, and the message generated=20
for asynchronous response will be processed before the return of the=20
onMessage() method.

3. Like DW has said, we don't recommend to use it when it is deployed in=20
an open environment, where the latency of the network is too unpredictabl=
e.

Hope this removes the confusion caused. Sorry about that, again.

Regards, -Patrick
