I just came across the following in the SCA Web Service binding spec:
227 2.2.3 Example PolicySet Providing The Conversation Intent 228 This policy set applies to binding.ws and provides the conversation intent. The conversation 229 intent is provided by using WS-ReliableMessaging protocol which has a concept of a Sequence. 230 This Sequence (which appears as a wsrm:Sequence SOAP header in the message) is used as a 231 correlation mechanism, on the wire, to implement conversational semantics. 232 <policySet name="WSRM-Sequence-based-conversation" 233 provides="sca:conversation" 234 appliesTo="sca:binding.ws"> 235 <wsp:Policy> 236 <wsrmp:RMAssertion 237 xmlns:wsrmp="http://docs.oasis-open.org/ws-rx/wsrmp/200608"/> 238 </wsp:Policy> 239 </policySet> It seems that we will need to do some more work in the Web Service binding to implement this. The WS-RM protocol looks quite complicated, much more so than WS-Addressing. I'm not sure yet what the minimal subset would be to support SCA conversational semantics. There's nothing in the Web Service binding spec about callbacks. I have sent a note to the OASIS Bindings TC mailing list requesting that the Bindings TC consider adding an interoperable protocol for callbacks to the Web Service binding specification.
