Sit back, relax and get a #Coffee+++! Thanks to the team for taking the time!
I had a post about the solution to suppress ADF LOV Like operator and prevent LOV popup loading when user is typing existing value - Suppressing ADF LOV Like Operator Filtering. Thanks to a blog reader, there was one use case found, when Like operator was not suppressed properly. This is fixed now and I would like to post updated sample application here.
Additional method is overridden in LOV VO implementation class - applyViewCriteria(ViewCriteria, boolean). (more...)

In this article I describe why you always should base your business object based upon an element, instead of a complexType.
With the Oracle BPM Suite your process data consists of project or process variables. Whenever the variable is based on a component, that component is either defined by some external composite (like a service), or is defined by the BPM composite itself, in which case it will be a Business Object. That Business (more...)
Just a short few days back I was at Devoxx Belgium. For those not in the know. Devoxx Belgium is the premier European java conference and is often referred to as the Java One of Europe. It's a developer centric conference. The folks in attendance are generally language geeks, jvm junkies, performance nuts and general java enthusiasts. We, Red Hat, have been sponsoring the event for a few years now and had a premier stand (more...)

If you look at a mobile twitter app you will see that, depending on connectivity, images are loaded instantaneously or delayed. In this post I explain how you can load the
Every now and then you look at some code and think that it cannot be possibly be wrong. Once you have ruled out a simple programmer screw up / enemy action in code (Make sure you read Java Puzzlers or similar) or a concurrency issue (Read Java Concurrency or go on Dr Heniz excellent course) you should sit back and take a few days and then starting thinking about whether the JDK is indeed (more...)

DZone made it again. Another one of their famous guides got published yesterday. This time it is all about Enterprise Integration.

"Out of all integration frameworks (EIP), ESBs, and integration suites, Spring Integration is the most popular (42%) and (more...)
Devoxx is nearly a wrap. Beside the general awesomeness, Stephan and his team launched a new content website to be the number one stop for all topics related to technologies which are relevant for Devoxx attendees. While I've been at GeeCon, Lucy asked me for an interview which I happily gave. So we get to chat about WildFly development and explains why the Java EE needs you. And about JBUGs (http://www.jboss.org/usergroups) (more...)
BPM Human Task activity is configured with outcomes. Based on these outcomes, buttons in ADF UI are constructed allowing user to perform different actions with the task. Auto generated ADF Human Task form contains a set of predefined buttons and this set is controller with rendered flag.

The Oracle Unified Method (OUM) Customer Program has been changed in that, next to the already existing option to get it by involving Oracle Consulting, you now also can buy it if (for some reason) you don't want to involve Consulting.
Next to that there also is the option to purchase a subscription (initial for 3 years, after which it can be renewed annually) allowing to download updates for OUM.
