0 0 Even though ADF does not always play nice with guests, it is becoming increasingly common to have ADF applications – pure ADF or WebCenter Portal – that are the host to embedded user interfaces, created in technologies such as Oracle JET, Vue.js, Angular or React. This is not the ideal […]
0 0 To select a country (or any other geographical entity), we can offer our end users a dropdown list, a list of values in a popup window, an auto suggest input text component or a more visual, map based approach. In this article, I describe the latter: Open a modal popup […]
0 0 In a recent article I discussed how the open source geo, GIS and map library OpenLayers can be used in an Oracle JET application. That article shows how countries selected in a standard Oracle JET Checkbox Set component are represented on a world map. In this article, we take this […]
0 0 Oracle JET is a toolkit for the creation of rich web applications. Many applications will have location-related aspects. Such applications can benefit from advanced map capabilities – for presenting data in maps, allowing users to interact with maps in order to formulate queries, navigate to relevant details or manipulate data. […]
0 0 The situation discussed in this article is as follows: a rich client web application (JavaScript based, could be created with Oracle JET or based on Angular/Vue/React/Ember/…) is embedded in an ADF or WebCenter Portal application. Users are authenticated in that application through a regular login procedure that leverages the OPSS […]
0 0 Here is my entry for the Oracle Developer Community ODC Appreciation Day (#ThanksODC). It is quite hard to make a choice for a feature to write about. So many to talk about. And almost every day another favorite of the month. Sliding time windows. The Oracle Developer Community – well, […]

0 0 Introduction AMIS has recently set up a brand new Enterprise Web Application team, of which I am proud to be a member. We will working in front-end development using a variety of Javascript based frameworks. As a first framework, we are currently investigating Oracle JET. After working through the Oracle […]
0 0 My objective in this article: describe how I (and therefore you) can use JSFiddle to create running, shared samples of Oracle JET code. This is useful for question on the JET Forum or on StackOverflow and also as demo/illustration along a blog post or other publication. JSFiddle is an IDE-like […]
0 0 As part of a SaaS Enablement project we are currently working on for a customer using Oracle JET, a requirement came up to present an hierarchical data set – in a way that quickly provides an overview as well as allows access to detail information and the ability to focus […]
0 0 A common requirement in any web application: allow the user to quickly drill down to records of interest by specifying relevant filters. The figure overhead shows two way of setting filters: by selecting from the [limited number of] existing values in a certain column – here Location – and by […]
0 0 Vue.js is a popular framework for developing rich client web applications, leveraging browsers for all they are worth. Vue.js has attracted a large number of developers that together have produced a large number of quite interesting reusable components. ADF Faces is itself a quite mature framework for the development of […]
0 0 A quick and rough guide on getting going with Node, npm and Vue.js 2 on a Enterprise Linux platform (Oracle Linux based on RedHat Linux) Install Node.JS on a Oracle Enterprise Linux system: as root: curl –silent –location https://rpm.nodesource.com/setup_8.x | bash – and: yum -y install nodejs (in order […]
0 0 In a recent blog article, I fiddle around a little with Vue.JS – Auto suggest with HTML5 Data List in Vue.js 2 application. For me, it was a nice little exercise to get going with properties and events, the basics for creating a custom component. It was fun to do, […]
0 0 This article shows data (News stories) retrieved from a public REST API (https://newsapi.org) in a nice and simple yet attractive Vue.js 2 application. In the example, the user selects a news source using a dropdown select component. I was wondering how hard – or easy – it would be to […]
0 0 Development of rich web applications can be done in various ways, using one or more of many frameworks. In the end it all boils down to HTML(5), CSS and JavaScript, run and interpreted by the browser. But the exact way of getting there differs. Server side oriented Web applications with […]
0 0 Node can push messages to browser clients, using WebSockets and the simpler Server Sent Events (SSE) mechanism. We will use the latter in this article – to push updates (event) to all subscribed browser clients. The browser loads index.html from the Node.js server. This file contains a JavaScript fragment that […]
0 0 In my previous blog I explained how to get ADF Data in a Jet Component, this was done by iterating through a ViewObject and rendering a component per element in the View Object. When you want to use the DVT’s from Oracle Jet, this won’t do the thing, because you […]
0 0 Oracle JET has been around for a while, and at this moment we are investigating what it would take to integrate JET with our existing ADF Application. In the current ADF application we want to make a dashboard in JET, however we still need to know for what project we […]
0 0 This article describes a simple Node.js application that uses Server Sent Events (SSE) technology to push updates to a simple HTML client, served through the Express framework. The updates originate from messages consumed from a Kafka Topic. Although the approach outlined in this article stands on its own, and does […]
0 0 In a recent article (Client Side Event Bus in Rich ADF Web Applications – for easier, faster decoupled interaction across regions), I proposed an approach for a client side event bus in ADF Faces Web Applications – as light weight, straightforward, simple alternative to contextual events. The article demonstrated how […]
0 0 The challenge is well known: our ADF Faces Web application is composed of various taskflows that have been developed as stand alone, encapsulated units that can be used and reused in various contexts. These taskflows can have come from third parties, remote development teams, other applications are we may have […]
0 0 Our challenge: we are building the new ERP system – a pure HTML5 browser based application in Oracle ADF. This application replaces the current Oracle Forms based application. For more than a year and a half – the users will have a hybrid situation on their hands: some of their […]
0 0 While developing a Oracle JET application against APIs on Oracle Service Bus interacting to JD Edwards and Oracle Transportation Management, we ran into a challenge. In the table (ojTable) that we had included in a page, we wanted to have column filters – fields in each column header where the […]

0 0 This is a short article about a big topic. About how JET Composite Components – small or pretty substantial – can be reused and integrated, not only in other JET applications (or components) but also in Oracle ADF applications and Application Builder CS. JET Composite Components are based on the […]
0 0 Recently, I used Heroku to deploy a website in the great wide open! In this blogpost I want to tell about my first steps using Heroku, including the rookie mistakes I made: so you don’t have to make them. Heroku in a nutshell: “Heroku is a cloud platform that lets […]
0 0 For one of my projects I need my users to log in to an 3rd party api (in my case strava) using oauth2.0 Framework of choice: AngularJS 1.5 in plain javascript, with the Angular 1.5 componentrouter. Since I have apikeys which I do not want to be known the the […]
0 0 While working on my Ionic 2 application, I made use of the exif.js library (for extracting meta-data from image files). Some of the key functions in this library are called and passed a callback function that is invoked when the image has been analyzed. From this callback function, I wanted […]
0 0 While working on a Ionic 2 (and Angular 2) application, I needed to make use of a 3rd party library (exif – https://github.com/exif-js/exif-js – to be exact, a JavaScript library for client side image analysis). This article describes the few steps I learned I had to go through in order […]
0 0 It has been a long standing ambition of mine to create an app that I could run on my iPhone. This weekend I finally realized that ambition – in what turned out to be a surprisingly simple fashion. Using various tutorials, tips from colleagues and the Ionic 2 framework, I […]
0 0 The challenge is simple: users of an ADF Faces web application are only allowed to enter uppercase characters into a field. We want to help them by turning any lowercase character they type into its uppercase equivalent – as they are typing. And we of course need to make sure […]
0 0 Adding Angular 2 to an existing ADF application Reality sometimes can be a bit surprising. The desire to build a new module using Angular 2 on top of an existing ADF 12.1.3 application for example probably wouldn’t be the first thing you would expect. But hey, with AMIS’ strong background […]
