I think offline functionality topic should become a trend in the future. Its great that Oracle already provides solution for offline - Oracle Offline Persistence toolkit. This is my second post related to offline support, read previous post - Oracle Offline Persistence Toolkit - Simple GET Response Example with JET. I have tested and explained with sample app how it works to handle simple GET response offline. While today I would like to go one step further and check how to...

Blockchain originally gained attention thanks to its connection to Bitcoin. But blockchain has emerged from under the crypto-currency’s shadow to become a powerful trend in enterprise IT -- and something that should be on every developer's radar.  For this program we’ve assembled a panel of blockchain experts to discuss the technology's impact, examine some use cases, and offer suggestions for developers who want to learn more in order to take advantage of the opportunities...

This week I had some interesting Oracle JET discussions with a couple of developers at one of our customers. One of the things was regarding the inline use of CSS that I found in the Views of the Modules. I didn't think that made sense so, after asking, I was told that this was because they did not find a way to use specific CSS per module. The question was if it was possible to use one specific CSS per Module in an Oracle JET Application. Besides that I thought it might also...

  In our previous blog we gave an overview of the various type of decisions that are available for a Decision Model. In this blog we show by means of an example that Decision Models can also be used for making complex decisions. We are going to make a decision model that determines the order of preparation of the pizzas in an order.The order of preparation is determined by the baking time, the total preparation time of each pizza and the number of available ovens (1 pizza per...

Welcome to the 3rd article on our new Blog series about Oracle JET and Oracle Cloud. Today we’ll start designing our application, starting with its Data Model. For that, well be focusing on Oracle’s SQL Developer Data Modeler as our tool and design the application’s underlying data model. So, without further ado, let’s dig right in. Data Modeling Workflow Let’s start our SQL Developer and go right into the Data Modeler. Open up the model browser and save the existing design with...

In one of our next posts we will implement the Decision Model in the Order Process. Before we do that we first explain the various type of decisions that are available for a Decision Model. The Decision Model editor in PCS (Process Cloud Service) or the later OIC (Oracle Integration Cloud) supports the DMN (Decision Modeling Notation) standard version 1.1, and uses FEEL (Friendly Enough Expression Language) to make decision modeling easier and more intuitive.In DMN all...

  JET Composite Components - are useful not only to build UI widgets, but also to group and simplify JET code. In this post, I will show how to wrap JET table into composite component and use all essential features, such as properties, methods, events and slots. Sample app code is available on GitHub. JET table is wrapped into composite component, it comes with slot for toolbar buttons: What is the benefit to wrap such components as JET table into your own composite? To name...

The essential message of this article is the automation for Oracle JET application of the flow from source code commit to a running application on Oracle Application Container Cloud, as shown in this picture: I will describe the inside of the “black box” (actually light blue in this picture) where the build, package and deploy are done for an Oracle JET application. The outline of the approach: a Docker Container is started in response to the code commit. This container...

In our previous blog we have made the first set up of our dynamic process. We created several stages and had the first processes, human tasks and milestones in there. Now that we have the first draft of the dynamic process, it is time to actually call some processes and human tasks from our dynamic process.In this blog we will explain how that is done. We already had imported the Preparation Process Application. But the delivery and payment are not part of this application....
