Re: [ebxmlms-develop] Sending/receiving acknowledgements

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

Sending/receiving acknowledgementsSorry for our late response.. you =
know, we hardly can find a break to breath recently.. :-(

1. We have added the ToUrlResolver interface (similar to Peter's =
suggestion) in the nightly build. We also added an implementation =
ToUrlResolverImpl. This implementation looks for URL from the ToPartyID. =
Of course, you can make your own implementation (to look up LDAP, etc.) =
and install the resolver in the msh.properties.xml. (Yes, this is a =
server-wide setting..., any objection?)

2. We have done the flowing the ACK to message listener long time ago.. =
:-) To use it, please turn on the "PositiveAcknowledgment" option in =
msh.properties.xml. When turned on and upon receiving the MSH-level ACK, =
Hermes will generate a StatusResponse message to message listener, with =
the RefToMessageID pointing to the referenced message. Prophetic =
feature, huh? ;-)

Regards, -Patrick

  A two part question on acknowledgements.=20

  First, I'd like to check some logic.=20

  The party ids of our messages are not of the form=20

  <eb:From>=20
    <eb:PartyId>http://from/msh/</eb:PartyId>=20
  </eb:From>=20

  Instead, they look like this:=20

  <eb:From>=20
    <eb:PartyId eb:type=3D"ABN">123456789</eb:PartyId>=20
    <eb:Role>Buyer</eb:Role>=20
  </eb:From>=20

  Normally, this doesn't seem to matter. However, when an =
acknowledgement is requested, MessageProcessor attempts to build the URL =
of the message recipient from the From PartyId. In our case, this is =
doomed to failure, and the acknowledgement message is sent to the local =
Hermes instead.

  Is this correct? If so, I'll have to add some more code to resolve a =
destination URL from a partyid, and fix MessageProcessor to use it.

  Second question: when an acknowledgement message is received, Hermes =
appears to swallow it, and doesn't send it on to my listener. How can I =
tell if an acknowledgement has arrived?

  Thanks.=20
