Tom,
There is certainly a lack of good definitions
in the area of conversations and callbacks that needs
to be dealt with at the Assembly level.
The current discussions in the SCA Java TC are giving the
conversation and callback capabilities
a thorough going-over.
The question of the correlation of callback
operations with specific forward operations arises when
considering the "callbackID"
defined in the Java specifications. This does in principle allow
the
client to set a callbackID which is
subsequently returned with each callback operation which
results from the original forward request
- and then to set a different callbackID for the next
forward operation.
So, this DOES imply correlation at the
message level when dealing with callbacks. Now, you
(and other folks!) may not agree with
this function, but that's how it's defined today.
Yours, Mike.

Subject
| [sca-bindings] Callbacks are correlated
at interface level, not operation level |
|
From assembly defintions, the callback inteface operations
are not
correlated to individual operations in the service interace. All
that is
required is the address to the callback interface port, corresponding to
the service interface.
I do not understand why we are talking about correlating callback
operation request messages with a specific service interface operation
request message.
Example Bidir Interace
Service interface PurchaseOrder
{
PostPO (in proposedPO type PO, out agreedPO type PO)
ammendPO (in proposedAmmend type PO, out agreedAmmend type PO)
}
Callback interface Invoice
{
PostInvoice (in proposedInvoice type Invoice, out agreedInvoice
type
Invoice)
ammendInvoice (in proposedAmmend type Invoice, out agreedAmmend
type
Invoice)
}
Question, which service interface operation request message should the
message id (or callback id) on the callback “request” message for
an
ammendInvoice operation invocation refer to?
