I'm a bit lost so let me try to give a concrete example. I am trying to understand the relationship between the EPR passed as a param here ( BpelEngine.createMessageExchange() ) and what the ODE deployment tooling has registered into the ODE process definition repository. I am assuming that the ODE message router will use the EPR to lookup a process definition from the repository. That being said the EndpointReference in Maciej's API looks quite opaque and so I'm a bit lost as to how deployment tooling and client collaborate through this EPR. It seems like we need to define a client key for identifying a process within the ODE registry.
I thought those are one and the same (i.e. EPRs you register into the process and the ones you use for message exchange), but I'll wait for Maceij to respond on that. If we use a bus, then the currency for communication is EPRs. The bus won't have any provision specific to process engines, it will use EPRs because they apply to any engine you deploy. But perhaps I'm not understanding the question correctly. Assaf
