Subject: NEW ISSUE: Callback Simplification
There’s 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 the JIRA. RAISER: TARGET: Java API and Annotation Specification DESCRIPTION: One of 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: - The scope of the client (4 possibilities) - The scope of the service provider (4 more possibilities) - Conversational or non-conversational on the main interface. - Conversational or non-conversational on the callback
interface. - User specified callback IDs - User specified callback objects. - The relationship of callback IDs to conversation IDs
(possibly user specified) - ...and probably more PROPOSAL: Not included. |
