im using
So its looks like this dependicies chain:
ProcessApp -> TK_SAP -> TK_COM
There is the serviceFlow with inputs externalServiceName, operationName and a serviceFlow ask for oAuth-token and call to target system using externalServiceName, operationName.
The problem is - when i try to invoke the BPMRESTRequest from TK_COM, i get NullPointerException because "externalServiceName" cant be resolved.
var request = new BPMRESTRequest();
request.externalServiceName = "language-translator-v2";
request.operationName="checkout";
...
var response = tw.system.invokeREST(request);
Im understand that switching the layers can help (serviceDefinition in lower TK-dependency), but it unlogisch is:
ProcessApp -> TK_COM -> TK_SAP
the answer is: JS-lib implementation. Implementing common functionality as JS-Server-file in TK_COM makes that a call to it from TK_SAP will instatiate JS-execution context in the TK_SAP namespace so all defined in TK_SAP externalServices and variables will be accesible by executing of JS-code (actualy provided by lower-dependency Toolkit)
