Luckily, neither CallbackIDs nor CallbackObjects
are mentioned in the assembly spec, so we may be able to handle a large part of
this simplification project entirely within the Java TC.

Subject: Re: [sca-j] NEW ISSUE:
you perhaps remember from the Assembly F2F meeting, I'm certainly all in favour
of simplification in
area of callbacks and conversations.
this issue being raised in the Java TC raises the question of whether all that
is intended is some
with the Java API for these capabilities, or whether the aim is a more general
a more general reworking is intended, then I think that a parallel issue needs
raising in the Assembly TC
I think that the Assembly TC defines the general concepts that must then be
implemented by the
affected TCs (which include at least the language implementation TCs and the

[sca-j] NEW ISSUE: Callback Simplification
been some informal discussion about the need to simplify callbacks and now some
email on the subject. I’ll suggest this issue to hang this
discussion on. I won’t put in a proposal, since I don’t think
we are yet at the stage where it is appropriate to have a proposal stored in
Java API and Annotation Specification
SCA’s goals is to present a simple programming model to service
developers. Unfortunately, the current capabilities related to callbacks
don’t really qualify as simple. Developers have to be able to
understand all of the possible combinations of:
scope of the client (4 possibilities)
scope of the service provider (4 more possibilities)
Conversational or non-conversational on the main interface.
Conversational or non-conversational on the callback interface.
specified callback IDs
specified callback objects.
relationship of callback IDs to conversation IDs (possibly user specified)
