we are in the process of rearchitecting our entire web channel architecture eventually extending to other delivery channels. There is strong emphasis of providing channel-independent services.
In this context, we are investigating whether SCA would provide a worthwhile approach to further reduce the dependencies between the various solution components (web application stack, ESB, backend systems). We are using spring to implement some of the services, WAS to host the web applications, WebSphere Message Broker as ESB.
It would be very helpful if you could post project experience from implementing SCA within the IBM websphere stack.
