OpenShift is the "open hybrid cloud application platform by Red Hat". It comes in different flavors and the most interesting part for most of the things you want to do is the public cloud application development and hosting platform "OpenShift Online
". You can easily try it out because using OpenShift Online in the cloud is free and it's easy. All it takes is an email address
. The free offering allows for up to three basic (more...)
If you want to run the Unified Push Server behind a firewall, you still need to expose those RESTful endpoints that are accessed from the mobile apps running on the different devices:
With the help of the Fabric8 Gateway Servlet this is a fairly simple task!
I have created such a gateway that only exposes the above URLs, nothing else. Checkout therepository on github!
Tableau Software is a self-service BI-tool that allows data visualisation, meaning that even business users should be able to easily visualise their data (without needing help of IT). You can check out the Tableau website for more information about this great tool.
As you may have already seen in several guides or tutorials, Tableau is able to link certain dimensions like postal code, countries, etc. to a certain geographical area. Unfortunately, most of these (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...)

I talked about scoping breakpoints for debugging purposes, next to scoping breakpoints JDeveloper has more interesting debugging features to offer.
I created a simple example to show both the watchpoint as well as the beep functionality. To illustrate this, I created a page with an inputText and a button, both bound to a backingBean.
This is the jsf code:
The code from the bean is also pretty straight forward:
We’ve been getting a lot of inquiries asking whether we have a tool that will automatically convert Oracle Forms applications to Formspider
We don’t have an automatic converter. We don’t view this as a disadvantage at all. We are solving the modernization problem with a different approach:
Formspider does not automatically converts your Forms applications to web apps but it converts your Forms developers to first rate web developers.
We think this approach produces the (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...)
Images are heavily used in Mobile apps. For instance a list that contains employees usually shows the images of these employees. This works well when you have a WIFI connection, but what if you are using slower connections ? 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...)
is a free version control tool for PL/SQL. Gitora hooks Git to the Oracle database and helps you manage your PL/SQL code easily.
It helps you perform common version control tasks such as reverting to previous commit point, branching, merging and cloning. Gitora updates the PL/SQL objects in the database automatically when version control tasks are performed eliminating the need to save files to an OS folder manually. It also implements a check-in check out (more...)
DZone made it again. Another one of their famous guides got published yesterday. This time it is all about Enterprise Integration. It contains articles by industry experts and the complete result from a survey of over 500 practitioners and developers which is probably the most interesting part. So, looking at the distribution of the different integration solutions:
"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
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.
OUM aims at supporting the (more...)
At Oracle OpenWorld, there was a lot of Oracle ADF material. I presented on Oracle ADF Bindings as part of the well-attended ADF track on User Group Sunday, and Oracle also gave some very interesting presentations on new and coming features in ADF. For example there is now an ADF component that you can use to visualize any network of nodes and edges.
But what struck me more was the fact that when Oracle buys (more...)
I am traveling a lot lately and catching up with the trip reports is not easy. One of my favorite trips lately was my visit in St. Petersburg, Russia for Jokerconf
