Best practice for calling web services from Oracle Process Cloud Service by Lykle Thijssen

More often than not, you will want your processes to interact with other services or processes inside or outside your enterprise. Since integration options are rather typical in Oracle Process Cloud Service, this article will help you to apply best practices for creating and managing your connections in a sustainable fashion.

Process Cloud integration points

Let’s say you have modelled a process in Oracle Process Cloud Service (PCS) for a private home loan application. Chances are quite high that this process will need some extra information to make the right decisions, like a credit check or a risk assessment and you will want to store the result of the application somewhere, for example in a database.

This requires several integration points in your PCS application. Now if you would directly import the WSDLs of those web services that you need to integrate with, it’s most likely not going to work. For example, Oracle Policy Automation, which you can use for risk assessment, has a highly generic interface and without XSLT support in PCS, you can’t make a proper request. Other services might require WS-Addressing or other technical aspects that PCS doesn’t support, so you need to put something in between. For this something, you can use various SOA and Service Bus products or Oracle’s Integration Cloud Service, once it has matured some more to deal with web services properly.

Creating the interface – challenges

So, you have decided to put one or more layers of services between PCS and the web services that you need to invoke. Regardless of your architecture, you need to keep some considerations in mind: Read the complete article here.
