Pivotal Cloud Foundry Spring Boot JPA demo written in Kotlin

I created the following demo for PCF using spring boot / PCF. After showing a colleague he decided he would write a Kotlin version of the same application. It's interesting to see how the Kotlin classes differ to those of Java.

The Kotlin version of the same application is here.

Kotlin is a functional language developed by the JetBrains guys. Its main benefits are:

  • Conciseness of code
  • Code safety - Null (more...)

Oracle SOA: Using Sensors on Optional Elements

In this posting I describe an issue you may run into when configuring composite sensors on optional elements, and why it is good practice to always add a filter that checks if the element is actually present.

If you define a sensor on a composite to record elements that are optional, you may find an error in the logs similar to the below:


If that is the case you probably have a composite that takes (more...)

Integrating Telstra SMS API with the Apigee Edge Service Broker for Pivotal Cloud Foundry (PCF)

Apigee and Pivotal partnered to provide comprehensive API management capabilities that expedite the scalable delivery of apps on the powerful Pivotal Cloud Foundry platform. Apigee Edge is available for rapid deployment as a partner service in the Pivotal Network

The following link talks about this service in detail

Why in Oracle BPM/SOA Suite Attaching a Fault Policy to a Synchronous Service Is Not a Good Idea

In this posting I will explain why in the Oracle BPM/SOA Suite you should not attach fault policies to synchronous services.

The other day I investigated some BPM process instance that had an unrecoverable error. It was calling a synchronous service, that on its turn was calling another synchronous service, that on its turn was calling a external, synchronous service exposed through the Oracle Service Bus. That latter call failed (due to a timeout). As (more...)

Red Samurai Oracle JET Mobile Hybrid App Live on Android

We have implemented Oracle JET mobile hybrid app in less than 30 minutes and deployed it to Android device. This was done as a demo to the customer and could prove Oracle JET offers effective approach for hybrid mobile app development. Development process isn't much complicated with JET once you familiarize yourself with JavaScript development process and learn how to interact with REST services.

Red Samurai app based on JET (using out of the box (more...)

Go Mobile with Oracle JET As Easy As 1 2 3

Oracle JET allows to build and run mobile hybrid applications. It is using Cordova to run on mobile device and provide access to device services. This is cool and what is great about it - it allows to get you started with mobile development in minutes. Besides all this - it is free.

I will describe steps I followed, to generate JET mobile hybrid app and run it in local browser (in the next posts (more...)

ADF BC Range Paging and ADF UI Table Pagination Use Case

ADF UI table pagination and ADF BC range paging sounds like a perfect combination. But to make it work perfect, a bit of extra effort is required. In the case of search/edit implementation, it can't remember updated record when navigating back to search screen (VO runs with Range Paging and UI table is displayed with pagination). I will explain how to solve it and show how to keep UI table displaying current page and prevent (more...)

Using the Oracle JET QuickStart Template

I will show in the post, how you can create single page applications with multiple modules in Oracle JET. As a starting point, you should use the Oracle JET QuickStart template, read about it here. This template comes with sample structure and you could follow it to split application functionality into different groups.

Download sample application, which is based on Oracle JET QuickStart template - JETCRUDApp_v10.zip (you must run ADF BC REST application in (more...)

How To Control Row Removal in ADF BC

There is a flaw in ADF BC remove operation. Row could be successfully removed in ADF BC - it dissapears from UI as well, but if there is DB integrity constraint violation - row is not removed in DB and error message is displayed to the user. This could be misleading to the user, he sees message about failed removal, but at the same time row is not present anymore.

Easier to explain with example. (more...)

#AMIS25 and The Oracle Cloud Shift : Insights from my first Holland trip


I would like to take this opportunity to wish AMIS Netherlands a very happy 25th birthday. In the context of Oracle SOA, the the name AMIS often keeps popping up - they have contributed a lot to the knowledge available to the community around this and related Oracle technology. 

As they chose to celebrate this occasion in a uniquely signature style - by holding a global Oracle conference with an impressive lineup of speakers (more...)

Oracle JET Executing Dynamic ADF BC REST URL

I'm going to explain how to call ADF BC REST service from JET API and how to control parameters passed through to REST URL. Most of the time, REST should return data based on different parameter values, URL is not static. I will be exploring two cases - search functionality, where parameter value is entered by the user and LOV functionality, where current employee key is submitted to fetch colleagues list.

How Cloud, Containers, Microservices and you can help Charity!

No, this isn't a customer success story. And this isn't the typical post about some awesome stuff that you can do with technology. This time it is actually about knowledge in a different kind. Lightbend would love to know how you use the Cloud, Containers and Microservices in your daily work. How Enterprises are adopting these technologies and last but not least, how influential are the decisions that are made in development to the final (more...)

Getting a name for someone to connect back to your server.

When doing test automation it is often the case you need to know the name of the current machine in order to prompt another machine to connect to it, particularly if you are running your tests in parallel. This week I was trying to get the server under test to connect back to a WireMock server running on the slave test machine.

The standard response on stack overflow is to use the following pattern to (more...)

Oracle JET Handling ADF BC 12.2.1 REST Validation Event

I already had a post about how to handle ADF BC validation messages in Oracle JET - Handling ADF BC 12.2.1 REST Validation in Oracle JET. There is an improvement I would like to share. JET submits data to ADF BC REST and there happens validation. In JET perspective data is correct, however it may fail validation in ADF BC and we need to reset values back to original in JET. Previously I (more...)
