OIC: Handling Optional Elements in a REST Integration by Jan Kettenis

This article is a follow-up of the a previous article where I discuss how to handle optional elements in case of XML in the Oracle Integration Cloud (OIC). In the following I discuss how to create an integration that invokes VBCS REST service and works in (almost) the same way as the VBCS REST service itself.
A challenge with mapping is always how to handle optional elements. In the previous posting that I refer to above, I describe a way how to deal with this in case of XML messages. As I found out (the hard way) this is cannot be applied 100% to JSON.
I have made it work for an integration that invokes the REST service on a VBCS business object. As there are challenges especially with numeric fields and references (foreign keys), I have used a simple BO called Detail having a string field, a number field and a reference. With VBCS BO’s the latter implies a number field that references the (number) id field of another BO it refers to, which in this case is called Master. Read the complete article here.
