IBM Content Collector error receiving response after external WS call - filenet-p8

Question

In my current project using IBM Content Collector 4.0.1 SP5 with IBM Filenet P8 Content Engine 5.2.1 I need to collect files from file system and add them to a certain P8's object store.
This issue is related and comes after this one.
The WS response must conform to a custom metadata source called Esito which contains two metadata properties called resultCode and message.
The call seems correct but when getting the response I can read this message in the log and the file is not uploaded into P8 Content Manager:

Could someone please explain me the correct format of the WS response JSON?
Could it be possible to use the One-Way mode instead of the Request-Response mode?

Answer 1

This issue seems to happen because of the incompatibility between the produce and the response body definition, based on the code snippet I had for your first post, your problem should be here:
produces = {MediaType.APPLICATION_JSON_VALUE, MediaType.APPLICATION_XML_VALUE })
#ResponseBody
String notificaArchiviazione(#RequestParam("fileName") String fileName, #RequestParam("esito") String esito)
The first parameter in produce is sat as JSONMediaType.APPLICATION_JSON_VALUE while in the response body you expect a string #RequestParam("fileName") String fileName
