OCI: When and How to Create an Integration to Call a Service from a Process? By Jan Kettenis

With the Oracle Integration Cloud, when you have to call a service from a Process you can choose to call an external service directly or you can put an Integration in between. This article gives some directives why you may want to do the latter, and how to prevent a pitfall that is easy to step in to.

To call a service you have to import the WSDL with it’s XSD’s. With that Business Types are auto-generated for all complexTypes in that XSD. Recently I was refactoring a case where this resulted in some 220 (!) Business Types being generated from 1 single external service, of which only a few were actually used. Granted, it concerned a service with a very complex interface, but for some reason all the external SOAP services we have to consume are moderate to very complex and easily generate 50+ Business Types. Not only that, they also use relatively long namespaces. Can you imagine what will happen when you have to call 5 of these services from the same Process application! You barely can see the forest from the trees, and you may find it pretty difficult to identify the correct Business Type to use for your request. The following example shows the selection list showing the types to chose from when creating a data object for one of the most simple cases we have. Read the complete article here.
