Reliable Messaging

[iwasa <iwasa@fsc.fujitsu.com>]

Krishna and All,

Let me submit POC-Tokyo demo spec for Reliable 
Messaging function. I believe POC group can show 
Reliable Messaging at Tokyo-POC, because there 
are five vendors have committed to show Reliable Messaging 
function and two vendors may be able to show it.
And as you know, Specification is on the TR&P mailing list.

Regards,
Iwasa

Reliable Messaging

The latest version of the ebXML TR&P Reliable
Messaging Specification Ver0.080 with following
update should be followed for Reliable Messaging
demonstration communications.

Update: Following sentence which is located at lines 123-125
             in v0.080 should be removed.

"Service and the Sender's Messaging Service will not 
  initiate a new message transmission until a current 
  message transmission has been correctly received."

Track 1 Scenario should be used for Reliable Messaging
demonstrations.  To show Reliable Messaging function,
one of following case (or both) should be used.

Case 1: Seller Ack fail

             Buyer                                 Seller
                     1)  Purchase Order
                -----------------------------> 
                     2)   Ack Fail         
                                   X   <-------------
                     3)  Send same message again         
                 ------------------------------->
                     4)    Ack
                  <------------------------------
                      5)  Acceptance
                  <------------------------------
                       6) Ack
                   ------------------------------->

After messaging with case 1, Seller should have
only one Purchase Order.


Case 2:Buyer send double message

             Buyer                                 Seller
                     1)  Purchase Order
                -----------------------------> 
                     2)  Purchase Order(same messageID with 1))
                ----------------------------->
                     3)    Ack for 1)
                  <------------------------------
                     4)    Ack for 2)
                  <------------------------------
                      5)  Acceptance
                  <------------------------------
                       6) Ack
                   ------------------------------->

only one Purchase Order.
