Where does WS-Addressing fit into a correlation scenario?

WS-BPEL 2.0 does not specify the use of WS-Addressing. WS-BPEL uses an endpoint reference, manifested as a service reference container <sref:service-ref>, to represent the data required to describe a partner service endpoint. A partner service endpoint may be manifested using WS-Addressing.

Stateful WS-Addressing Endpoint References (i.e. EPRs with Reference Parameters) may be used for identifying instances of WS-BPEL processes. This approach can be used as an alternative to using WS-BPEL correlation sets.

Kind Regards
