|Subject:||NEW ISSUE: The EJB bindings specification should provide explicity statesupport or non-support for Callbacks|

I'm forwarding this binding TC email to the SCA-J TC for awareness and consideration. This TC owns one binding spec, the EJB binding, and I believe we should also at least consider this issue.
FWIW, a search of the latest EJB binding working draft does not reveal any references to "callback" (though my memory was that we made statements of non-support in the spec, apparently we don't). There is a section on conversations mapped to stateful session beans so I believe that aspect is covered. Thus the issue:
Raiser: Dave Booz
Target: EJB Binding specification
At present, the EJB binding spec is completely silent on callbacks as described in the Assembly specification. My assertion is that each binding spec is obligated to clearly state what is and is not supported from the Assembly specification. I don't believe that silence is sufficient due to the inter-relationship of the various SCA specifications.
The SCA-Bindings TC is considering a similar question for each of the binding specs owned by that TC.
None at present.

At present, it is not clear which, if any, of the Bindings specifications enable the implementation of two important features of SCA described in the Assembly specification - namely Callback interfaces and Conversational interfaces.
Each of the Bindings specifications should explicitly declare if it is possible to support each of these features.
For each of the Bindings specifications that claim to support either or both of these features, the specification should provide a full description of at least one exemplary implementation of the feature using the Binding technology described in the specification. Multiple alternative implementations are permitted and may be added to the specification.
For example, it may be possible to implement Callbacks using WS-Addressing capabilities with Web services. If so, and example, showing the use of appropriate features of WS-Addressing and other relevant WS-* capabilities should be added to the specification. If an alternative exists using (say) WS-Context, then an example based on that technology can also be provided.
None at present.
