Use Oracle Integration to Add Attachments to a Process Instance

Use Oracle Integration to Add Attachments to a Process Instance by Bogdan Eremiaimage

The other day it came to my attention that it’s not really straightforward to add attachments to an Oracle Process Instance using the REST API.

One reason for this is that it requires multipart/mixed media type for the request body message format, and producing this kind format is not so common for JavaScript clients. The JS clients are more used to working with multipart/form-data, the de-facto standard for form-based file upload in HTML.

One way of overcoming this is to use Oracle Integration Cloud (OIC) between the JS client and Process REST API. OIC has a REST Technology Adapter that supports sending/receiving attachments in both multipart/mixed and multipart/form-data media types. The goal is to shape in OIC a REST interface that accepts multipart/form-data, to do a translation into multipart/mixed (alongside with other transformations/actions if required) and to call the Process REST API. Below are the main steps for achieving this.

1. Create a REST Connection in OIC for Process REST API.

Go to OIC Homepage > Designer > Connections to create a new connection by selecting the REST Adapter. Read the complete article here.
