    WS-Eventing, EDA

    ahmingus

      The JBoss ESB literature references EDA support, a "notification service to allow the ESB to register events", and WS-Eventing support. I notice, for example, that there is WS-Eventing support in JBossWS, but the ws-eventing tests are missing from the 2.0.2 download. I wasn't able to identify ws-eventing support, nor any reference to any other notification service in the ESB documentation.

      I would love some help in comprehending the extent to which eventing support exists in the product, and whether anyone has any experience implementing it.

      Thank you in advance.

          You should ask in the JBossWS forum about WS-Eventing (but note that WS-Eventing as a specification is going to be significantly changed in the future).

          As for the ESB, the underlying infrastructure is event-oriented. Your services register for the receive-message event. I view EDA as a way of layering on a SOA, or reasoning about a SOA, rather than in just terms of messages. The next major release of the ESB should provide more support for events at the higher level.

          You may want to take a look at the sandbox too.

            Thanks for the prompt reply Mark.

            I suppose I was half-hoping that there was some configurable, abstracted bus support for web service-based pub sub, whether layered on the JBossWS WS-Eventing or not.

            I envy you feeling comfortable about what EDA is ;). To me it just looks like mediated pub/sub messaging + CEP and is thus orthagonal to SOA, but opinions on this are pretty diverse.

              Different opinions are good :-)
