CAF Service modeling power limited?

Question

Hi, I tried to wrap a web service with a CAF service. All works fine except for the mapping between the model in CAF and the model from the web service: in web service you can have arbitrarily deep structure in your model, but it seems CAF modeling allows at most a depth of three: the root, under the root complex attributes are allowed, which can only contain simple attributes or reference to existing custom simple data types. so it looks like (at least to me) it's not possible to wrap a complex web service to a CAF service. Am I wrong? Is there any workaround for this?
Best regards,

Answer 1

mapping CAF entity attributes to External service attributes is limited. You cannot defiend nested structures on the CAF entity side. You cannot map collection structures between CAF entity and external service.
The solution at least in nw04s is to create an application service on top of the entity and do the mapping via java coding.
CAF is useful if you need local data persistency. If you just need a service layer abstraction (wrapper layer) to sub-systems, without additional data or logic, it can be a little cumbersome to add CAF between the UI or Process Layers and the Service Layer. But at the end it depends on your solution architecture. It'll make sense if your UI or Process Layer is very different (technologywise) from your Service Layer.
