Last week I helped someone on the Oracle community forums with transforming a comma separated string to a list of elements. He needed this to process each element in BPM Suite, but it is a use case that can come around in SOA Suite or even in Oracle Integration Cloud. You would think that you could do something like a for-each and trimming the element from the variable. Recursion One typical thing with XSLT is that variables are immutable. That means that you can declare a...

The last article First steps in serverless with fnproject.io marked the start of my journey into serverless computing. My first proof of concept in this area was quite promising so I have decided to continue on this path and do a couple more experiments. I have a set of use cases in mind where serverless architectures might be beneficial for certain integration scenarios that include Systems, People and Developers. Overview In this article I’m going to explore the use of...

In the recent months I’m reading a lot about FaaS and Serverless as yet another way to build software systems and I must say I have become quite enthusiastic about it. In fact much more enthusiastic than with micro services when they were considered the greatest thing on earth for development for the Cloud. Not that Serverless doesn’t have any caveats but it seems to fit the idea of Cloud as an utility so much more than having tons of Microservices up and running for the...

Oracle Integration Cloud is finalizing its work of a UiPath specific adapter that allows Oracle Integration Cloud service subscribers to connect to a UiPath Orchestrator. Oracle Integration Cloud allows dispatching UiPath RPA Processes via UiPath’s public REST API. Oracle offers bi-directional communication between Oracle Integration Cloud and UiPath RPA solution. When Oracle Integration Cloud consumes developed and deployed UiPath RPA processes, Oracle Integration Cloud can...

What if we told you that you don’t have to create microservices with Java EE anymore? Meet Project Helidon, a set of Java libraries for writing microservices. This new project from Oracle currently supports two programming models: Helidon MP and SE. Let’s have a closer look at it! If you need an easier way to build microservices, you should give Project Helidon a try. Although Oracle has just open sourced this set of Java libraries, the project itself is not new, as Dmitry...

I define my input as follows – So now to the 2 simple rules – IF/THEN rule and a Decision Table – The rules are self-explanatory. I want to expose these as 2 separate services – I now Activate -Back in the Process App – Now I drop a Decision Activity in my process – Very succinct! Now all I need to do is the data mapping - Read the complete article here.   PaaS Partner Community For regular information on Oracle PaaS become a member in the SOA & BPM Partner Community for registration...

I was recently working on a simple process in PCS for a license approval flow. Given the purists that I am, I began by defining definitions for the various message based activities used in the process flow. The process was an asynchronous process with a few intermediate events. A simplified snippet is shown here for visualization. In order to implement the above process, I created a service definition (WSDL) with the following schematic. As you can notice, there is a portType...

Oracle have announced another Open Source project called Helidon (Helidon.io) as a microservices platform built on top of Netty (which is built around a contemporary async model). If you look at the literature you’ll note two flavours one called SE which aligns to the programming characteristics or Node.js – asynchronous. The other is MP which aligns to the rapidly evolving J2EE MicroProfile which essentially follows a coding style along the lines of J2EE annotations. Whilst...

Introduction There is a lot of hype around Microservices and the use of events for implementing the choreography pattern. However this is nice for companies like Netflix and Twitter, but there are a lot of organisations still struggling with files and ESB like products. Also my current client uses an ESB namely the Oracle SOA Suite 12c for integrations. We cannot just throw away this ESB, but we can make use of the event mechanism built in. This blog describes the way we use...
