VBCS: Calling a REST endpoint by Richard Olrichs

Oracle Application Builder Cloud Service (ABCS) has been renamed to Visual Builder Cloud Service (VBCS), so this blog series about ABCS continues as a blog series about VBCS. In this blog I will explain how to call a REST endpoint and create a Business Object based on this REST Service. There are several ways to do this, but I will start with the most basic one. The data that we get from the REST service will only be presented (read-only), we will not send updates/posts to the REST endpoint.

To call the REST endpoint, we will use a template provided within VBCS that we are going to adjust just a little bit. We can do the editing of the 2 javascript files within VBCS itself. This is a temporary solution, Oracle is working on making these configurable and even more easy to use for users. Read the complete article here.

Jarvis Pizzeria: Decision Model in the Delivery Process by Richard Olrichs

To make the delivery of the pizzas to our customer, we need to decide how to deliver the pizzas. In our process we’ve already got the order data, so we know what the order is and where it needs to be delivered, but what is the best way to deliver the pizzas?

We will create a decision model in PCS to help us with this decision. In the delivery process we will call the decision model like a service and use the answer to make the correct decision.

The input for the decision model will be the amount of pizzas and the distance to the customer. Based on these data we will decide to either use a bike, moped or car to do the delivery. A very common decision to make in the Netherlands, since we love our bikes and often deliver pizzas by bike rather than by car.

We start with going to the PCS home. All the way out of the jarvis application and on this home menu we click the create button. Here we see that besides new applications, we can also create a new decision model. This means the decision is not coupled directly to the application with our processes, but it is a stand alone decision model. Read the complete article here.

Jarvis Pizzeria: Using the SOAP interface to start a Process by Richard Olrichs

We as old-fashioned SOA/BPM Suite developers, are used to test deployed services using tools like SoapUI. In this blog post, we will show you how to start a Process in the Oracle Process Cloud from the SOAP UI interface.

On premises with SOA or BPM we used to start by obtaining the required wsdl from the Enterprise Manager.

However, for PCS there is no such thing as an Enterprise Manager, so how do we get the WSDL?
In the top right corner of the PCS Composer there is a ‘Management’ button. Read the complete article here.

Jarvis Pizzeria: Implementing Rules by Richard Olrichs

When the order comes in, payment needs to be made first before we start preparing the pizza. Our order payment process supports three possible payment options:

• Creditcard: obviously a commonly accepted payment option
• Cash: although we are a very tech-savvy company we would also like our old-fashioned customers to be able to pay the pizza with cash money
• Deferred payment: our most trusted customers can pay their order in a deferred way.  Deferred payment means the customer receives an invoice per email and is asked to pay the order within two weeks.

The payment process is depicted below. The first activity in the process is concerned with determining which payment options are available. What component can we use to insert some facts, start reasoning about those facts and give us an answer based on those facts? Of course…Oracle’s own business rules! Read the complete article here.

CORS Support in Oracle Process Cloud Service by Antonis Antoniou

The latest August 2017 release has announced the long awaited support of Oracle Process Cloud Service embeddable components and REST APIs in CORS.
CORS stands for Cross-Origin Resource Sharing and it is a mechanism that allows restricted resources  on a web page to be requested from another domain outside the domain from which the first resource was served [1].
CORS is especially useful with REST services since in most of the cases, you will have a REST endpoint residing in a dedicated "API" domain. A very common scenario is consuming one of the Oracle PCS REST APIs from a completely different "client" domain.
Without Oracle’s PCS support in CORS this would not have been possible.
Another very powerful feature that has been around in Oracle PCS is the ability to embed Oracle PCS functionality in external applications in the form of jQuery widgets.

The following functionality is exposed as jQuery components: Read the complete article here.
