In-Depth Information
As we are discussing the cooperation of service edges (the composition member's end-
points) and composition controller, we do not have much freedom here at OSB, especially
at the South end (see the figure from the
Maintaining Exception Discoverability
section
again). We should be very careful with individual handlers, as they can be quite off from
the entire composition logic; technically, we should be concerned about three main things:
• Log the caught error (the first step in the preceding figure) properly.
• Update the message tracking information in the XML container to help the ser-
vice broker with error resolution. We can even perform the conversion of the error
code if necessary, but this will usually require SR lookup.
