Hi,
I found this in Web Services Coordination (WS-Coordination) Version
1.1 which was released on 12 July 2007. According to my understanding,
there is an issue like this.
In Figure 2 (i.e. Two applications with their own coordinators), the
step number 4 says, "Register Passing Y and App2 Returning Ya". Here I
think it should be "Register Passing Y and App2 Returning Yb". In other
words, App2 receiver the EPR of Yb but not that of Ya.
Please correct me if I am wrong.

Cheers,

Danushka

Hi Danushka,
Thanks for your comment.

I believe the figure is correct as it stands - steps 4 and 5 show in
principle how a received CoordinationContext at App2 can result in the
registration of a transaction participant associated with App2 with the
transaction coordinator associated with App 1. The end result of the
registration of Yb is a response that contains Ya. This is clear from the
text that describes Figure 2; the notation "Returning Ya" on the arrow for
step 4 in the figure is really the result of both steps 4 and 5. The
figure is simply an illustration of one possible implementation in which
step 4 calls step 5 and returns its result. In practise, the
WS-Coordination specification precisely defines the interoperable protocol
illustrated in step 5 whereas step 4 in the figure simply illustrates one
mechanism by which this can be caused to occur.

Regards,
Ian Robinson
