Re: [ebxmlms-general] Hermes servlet problem

Thanks for the clarification - then I don't know why I couldn't get it =
to work, I'm quite sure my smtp config was correct as I was able to send =
messages trough hermes, just not deliver ack's.=20
It's not so important for me any more - but if someone can see what's =
wrong from the following log transcript I'd be happy to know about it:

I've been trying to set up Hermes to recieve messages from the ebMail =
client application, and send read acknowledgements, but it looks like =
Hermes isn't sending the requested acks. =20
I check off "request read reciept" in ebMail (using the default PO =
example plugin). Looking at the message repository for Hermes, it seems =
like Hermes is preparing the acknowledgements, it just doesn't seem like =
it gets sent. Am I missing something...?
Here is some of the log data for the reception of the message:=20

Emne: Re: [ebxmlms-general] Hermes servlet problem

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 =

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 =

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 =

an open environment, where the latency of the network is too =
unpredictable.

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

Regards, -Patrick
