Hi,
I need to distinguish these errors in a service call:
1) The application does not answer (timeout)
2) The connector is down
3) The application answers with an error
I put a decision node but I am not able to distinguish the situations (2) and (3). I think they both return a ServiceCall exception.
It is very important because while (2) is a technical problem, (3) is a business error.
Any idea?

If application answers with an error that should be a part of your response BO and is not a Service Call Exception.

Ok, let's say that the application answers with an Error and that I have an application specific business object that contains the error.
I belive that only the application specific business error would have the error information while the generic business object would not. In that case, the map should fail (throw a MapFailureException), but how will the collaboration distinguish that exception if the connector sends it as a ServiceCallException?
On the other hand, the generic business object could contain the error information too, but would every generic business object contain that information?
Thanks for your help. |

I am not sure that I understand you. For Service call exceptions have a decision node with Exception path to handle them.
