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 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 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 […]
0 0 The first baby steps.. This is the first of a three part blog series. Each of these blog posts explain a small part of the ServiceWorker API. In this part, we begin with the basics. Even though ServiceWorkers are still a ‘working draft’, they are here to stay. Firefox, Chrome […]

0 0 In demos and tutorials we only care about the happy-flow of our applications. That is ok, because we only run that code in our own little predictable environment and leaving everything else out makes any framework look nice and easy. Often in blog posts “error handling and such is left as […]
0 0 “ There’s A Lot More Behind This Pretty Face “ The whitepaper “User Experience Frameworks – Future of optimal UI development -” starts with an overview of user experience guidelines. These guidelines translate to additional UX requirements when designing and building a new user interface on modern systems. We will also […]

0 0 Like other web applications, Oracle ADF applications potentially use a lot of JVM memory. Many times, the root cause of a high memory usage is that application data retrieved from the database into memory is not properly limited; hundreds or thousands of rows (with too many attributes) are fetched and […]
0 0 Performance needs to be ingrained in your application – it cannot be added in during the last stages of development. In this video I discuss how you can optimize the performance of your Oracle ADF Fusion application, diagnose and solve typical performance problems, and build an efficient, responsive, scalable ADF […]
0 0 Oracle wants to lead in User Experience. Plain and simple. To that end, it has established the Applications User Experience team (back in 2007) – a relatively independent team within Oracle that explores all kinds of UX options, conceptual and technology wise, and translates them into guidelines, templates, buildings blocks […]
0 0 Tag Clouds are an interesting way to present information. They very quickly convey an impression of the relative sizes of a substantial number of entities and they do so in an attractive, almost playful way. By making the tags clickable, tag cloud can also be used to quickly navigate or […]
0 0 The convergence project between Oracle’s JVMs JRockit and Hotspot is making significant progress. Included in the latest Java 7 JDK update (‘7u40’) is a new powerful monitor tool: Java Mission Control (JMC). JMC is a production time tool that has its roots in the JRockit JVM tooling. It is located in the […]
0 0 Last week’s JavaOne conference provided insights in the roadmap for the Java platform as well as in the current state of things in the Java community. The close relationship between Oracle and IBM concerning Java, the (continuing) lack of such a relationship with Google, the support from Microsoft for Java […]
0 0 As every year, Open World is again packed with sessions, meetings, announcements, Demo grounds, Hands-on labs, events, music. My calendar is rapidly filling up but I keep on discovering other interesting sessions and it’s a constant challenge to plan everything and to have a good overview of all alternatives. In […]

0 0 One of the brand new specifications in Java EE 7 is JSR-352 Batch Applications for the Java Platform. This specification describes how Java EE containers will allow applications to run batch jobs in a standardized way. Such a batch job can be scheduled (to be started by the container) or […]
0 0 In this article, I show how I have created a simple and fairly meaningless Java EE 7 application that uses a number of smart Java EE features: a stateless session bean has a scheduled method (that is triggered every 3 seconds) the stateless session bean publishes custom CDI events a […]
0 0 In this post I would like to share an example how to deploy an .ear file with an Ant script to the Oracle Application Server 10.1.3 (OAS). Automatic deployment can help improve the release process. First of all because manual deployment usually costs time of the developers. Especially the lead […]
0 0 Whether you are deciding on the framework to use for your next Java web or mobile project or whether you are contemplating your next career step as a Java EE developer, ADF should be on your short list for consideration. With a new free version, deployment on many application servers […]

0 0 The show is over, the people are gone and the cleaning can start. What do we take home from JavaOne 2012? That depends on who you ask. Some people primarily will have taken goodies from the exhibition floors with them while other may have focused on less tangible goods and […]
0 0 One of my favorite areas of ADF is Data Visualization. The rich, interactive and (un)usually attractive components that allow me to spice up an ADF application in a very easy straightforward way have a special appeal. We all know that pictures speak volumes. And that a plain table presents data […]
0 0 Session at JavaOne come in various shapes. Some are visionary, high level and future oriented. Others are detailed and discuss practical, sometimes very fine grained topics. One of the sessions I attended was somewhere in between: future oriented yet pretty concrete at the same time. It was probably my favorite […]
0 0 JavaOne 2012 is underway. While the double entendre of ‘SUNday’ no longer exists, this first day is still an important day. To set the stage, manage expectations, build on the atmosphere and layout the roadmap (starting that sometimes not even subtle massaging of the minds). The keynote sessions are the […]
0 0 Performance of Enterprise Java Applications is a requirement and usually a challenge. Business requirements on systems can be stiff, successful systems can easily be overloaded and complex application architectures can add a burden too. Improving performance by tuning the application after it has been built seldomly renders huge improvements. By […]
