Introduction
In this 3 part blog series, I will be demonstrating on how to use PCS to invoke OSB (On-Prem or SOACS) services and upload a report/doc generated using BI Publisher to DOCS. The following components are used in this demonstration:
- Oracle Document Cloud Service (DOCS)
- Process Cloud Service (PCS) with DOCS integration configured.
- BI Publisher 12.2.1 with sample reports installed
- SOACS with OSB or OSB On-Prem.
In this blog series, I will be covering the following topics:
Part 1 – Overview and Setup (Part 1) – cover the use case, configuration steps for PCS, BI Publisher and DOCS REST Services.
Part 2 – OSB Services Design (Part 2) – cover the OSB service design in details and what you need to look out for when you design your OSB services.
Part 3 – PCS Application Design and Testing (Part 3) – cover the PCS process design and how to test the sample project.
Use Case
We will use PCS to design a Salary Report request process, the process allows the user to submit a salary report request and generate a PDF report in BI Publisher. We also need to create a report folder dynamically and attach the PDF report to the newly created folder in the same PCS process instance so that we can review and approve the generated report.
PCS and DOCS Integration
We will need to configure PCS and DOCS integration in order for this demonstration to work, the instruction for PCS and DOCS configuration can be found here.
We will use the default folder structure in this demonstration. However, you can also configure the folder structure (shown below) if it’s required.
Once the PCS and DOCS integration has been configured, when a process is initiated, a process folder for that process instance will be created in DOCS. We can then login to DOCS using the same username and password we used to configure PCS and DOCS integration to review the folder structure:
DOCS REST Services
DOCS exposes number of REST services to retrieve folder/item information and upload the file using multipart messages. In this demonstration, we will use the following DOCS REST API to retrieve the folder ID and upload file:
| Resource URI | Method | Description |
| /api/1.1/folders/items | GET | Get a collection of all items (folders and files) that user has access to, including folders that others have shared with that user. The type field indicates if an item is a folder or file. |
| /api/1.1/folders/{folder id} | GET | Get folder information (metadata) for the specified folder. |
| /api/1.1/folders/{folder id} | POST | Create a new subfolder in the specified destination folder. |
| /api/1.1/folders/{folder id}/items | GET | Get a collection of child items (folders and files) in the specified folder. The type field indicates if an item is a folder or file. |
| /api/1.1/files/data | POST | Upload a new file using a multipart request to specify destination and file information. |
BI Publisher
BI Publisher exposes a web service called report service, which has an operation called runReport. This operation allows you to run a report with or without input parameters and return the generated report in base64 encoded data format. A list of operations available in BI Report Service is here
In this demonstration, we will be using the sample report called SalaryReport without parameter, the generated report will be a PDF file in base64 encoded data format.
SOACS and OSB on-premise
If you are planning to use SOACS, you will need to expose the BI Publisher report service externally so it can be invoked by SOACS. If you are using OSB on-premise to invoke the BI Publisher report service, you will need to expose the OSB service externally to allow PCS to invoke, and you will also need to import the SSL certificate from DOCS to your OSB managed server trust store.
Summary
In this first part of this blog series, we have covered the use case, basic integration configuration and setup required for the PCS, DOCS, BI Publisher and OSB. In part 2 of the blog, we will examine OSB services design in detail.
