Oracle Cloud and Fusion Middleware, Oracle JET, Jakarta EE and all other Open Source Blog!

Since 2019 I have not been active blogging or participating in speaking conferences. In addition, I stopped working with Oracle technologies and that's why this blog has been since that stopped. I am going to start now blogging about: Camunda BPM Pure Java Spring Boot Old videoconsole games programming such as Nintendo NES, Sega Saturn etc... (which is a new hobby for me) About Methodologies, Enterprise Architecture and specially about mistakes and bad decisions taken in real life projects. I am going to keep this old blog open just in case there are still Oracle Fusion Middleware or old Oracle ADF people who needs some content

Hello Oracle JET lovers, In this post I will bring a small example on how to handle two common errors when Routing in Oracle JET. Routing to a State Id which has not been registered as part of the Router configuration Routing to an existing State Id, however when calculating the corresponding View and View Model they are missplaced, no-exist or whatever cause it makes the module to do not load properly The example is based on the scaffold Oracle JET Application navdrawer (without TypeScript). GitHub: ojet-page-not-found-handling Taking a look into the code provided by navdrawer , navigation is implemented as following: The index.html uses oj-navigation-list where selection is bind to router.stateId which will immediately trigger the Router to route to the new stateId The appController.js (View Model for the index.html) configure the possible Router States // Router setup self.router = oj.Router.rootInstance; self.router.configure({ 'dashboar

This is an example on how to select all other options by using another oj-checkboxset. GitHub: ojet-checkbockset-select-all The idea is to keep track of the selection and make use of the on-value-changed as described in the following code. self.colorOptions = ko.observableArray([ { id: "blueopt", value: "blue", color: "Blue" }, { id: "greenopt", value: "green", color: "Green" }, { id: "redopt", value: "red", color: "Red" }, { id: "limeopt", value: "lime", color: "Lime" }, { id: "aquaopt", value: "aqua", color: "Aqua" }, ]); self.selectAll = ko.observableArray([]); self.currentColor = ko.observableArray(["red"]); self.selectAllOptionChanged = (event) => { const newSelection = event.detail.value; if (newSelection.indexOf('all')

Recently I have been asked of one of my team colleagues about how we can generate some Oracle JET components once the View Model has been loaded. GitHub: ojet-add-jet-comp-programmatically Researching a bit in Knockout / JET and how the Binding Context works I found the following approach. In the transitionCompleted lifecycle method, the DOM has already been generated, so we can use JavaScript API to get the DOM component what will we use to add Oracle JET Components. By using insertAdjacentHTML method, we will add our Oracle JET Components. In addition, you can already bind the methods / attributes to Knockout Obvervables if required. self.transitionCompleted = function () { // Implement if needed const fakeDiv = document.getElementById('fake'); fakeDiv.insertAdjacentHTML('beforeend',' '); fakeDiv.insertAdjacentHTML('beforeend',' Desktop Laptop Tablet ' ) ko.cleanNode(fakeDiv); ko.ap

Hi, After a long time waiting for it, the Oracle Fusion Middleware 12.2.1.4 has been finally released. Oracle Fusion Middleware 12.2.1.4 Official Documentation In this post, I will focus on my personal view over the Oracle Fusion Middleware products which I most commonly use over the last 8 years which are the SOA Suite (including BPM and OSB), WebCenter Suite (Portal, Content, Sites), Oracle ADF and Oracle WebLogic Application Server mainly. Certification Matrix As every release, I make a round around the Certification Matrix of every Oracle Fusion Middleware Release to check if the Java JDK accepted has been increased or not. Oracle Certification Matrix for Oracle Fusion Middleware 12.2.1.4 Java However, I found that we are still in the J2SE / J2EE 8 and the maximum certified JDK is Oracle JDK 1.8.0_211+ which means any 1.8.0_xxx if you are using Oracle JDK as the JDK vendor. Database The biggest new is the certification with 18.3+ and 19.3+ of the On-Premise vers

In this post I bring another example on how to Communicate Modules using the Oracle JET - TypeScript Template based on the Oracle JET Cookbook: InterModule Communication From now and so on will create multiple examples using TypeScript for those who are not familiar with it and wants to turn the Cookbook examples into TypeScript :). The example ( ojet-typescript-list-detail ) can be found as usual in my GitHub repository: https://github.com/DanielMerchan/ojet-examples This example is a bit different compared to the Cookbook example where the modules are not running at the same time within a Module. This example is built as described in the following images: Customers module acts as the Wrapper Module. It coordinates when to load the list and detail modules. Customers module makes use also of signals npm module for communication between Customers-List, Customers-Detail. Explanation of the Example customers.js is the coordinator responsible module for: initiali

Oracle JET supports officially TypeScript for your application development. OJET CLI does NOT include templates which uses by default TypeScript. However, in the Oracle website they provide an starting point template in case you want to use TypeScript. JET TypeScript Starter Template - Web NavBar In my GitHub you can find the app fixed: ( ojet-typescript-template ) https://github.com/DanielMerchan/ojet-examples The application has a minor bug in its Router configuration which makes the following strange behaviour: If you copy any module URL such as http://localhost:8000/? root=incidents in your browsers it always load the default module which is the dashboard Why? How to fix it? In the TypeScript template there is a duplication of the Router configuration. You can find a self.router.configure in: root.ts which acts as the "main.js" of the Oralce JET Out-of-the-box basic templates created with OJET CLI appController.ts which is the appController.js of t
