Configuring Mediator in Agnostic Composition Controller
Do you remember that in the first release of our Service Broker, we have two mediators
for synchronous and asynchronous processes? The logic we will cover next is applicable
for each of them.
Firstly, by decoupling (isolation) our business delegate BPEL process from actual service-
workers, we have to anticipate different MEPS involved in service activities. Yes, we have
already demonstrated that Mediator can initially be created with either synchronous or
asynchronous interfaces (we will discuss one-way and event-based later).
This fact, though, is significant for SCA dehydration routines (Mediator
is
a stateful com-
ponent whereas OSB is
not
) and for the definition of the Port Type; naturally, the sync in-
terface has one Port Type as the response that is returned to the caller, whereas, for async,
you can define Callback Port Type for response messages.
