A long tail is a distribution of some data point where a few data point have a high value, but most of the data points have a much lower value. When sorting the data points by value, there will be a large “head” and a long “tail”.

If you are working with Oracle software as a developer, DBA or application server administrator, you should read the new OTech Magazine.
The Winter 2014 issue is almost a book: 136 pages of high-quality technology articles by some of the leading experts in their respective fields. My contribution is the article “From Requirements to Tool Choice” about how to choose the right Oracle development tools (ADF, APEX, or Forms).
And did I mention it (more...)
The first issue of my ADF Mastery newsletter has just been published (sign up here if you missed it). In this issue, I discuss Oracle ADF skill levels.
If builders built buildings the way programmers wrote programs, then the first woodpecker that came along would destroy civilization.

Too many programmers simply Google for a code snippet that seems like it might solve the problem at hand, and use it (more...)
I’m establishing an ADF community here in Denmark (primarily Copenhagen) where we can meet face to face and discuss our ADF projects and challenges across companies and projects. The next meeting is on January 7 – please sign up here:
In 2014, I’ll be sending out a monthly ADF newsletter to help you on your way towards mastering ADF. If you sign up for the newsletter before Christmas, you’ll be entered into the drawing for a copy of my latest book “Developing Web Applications with Oracle ADF Essentials”. Sign up (more...)
Here is my experiences with installing ADF 188.8.131.52.0 on Red Hat 6 (64-bit) using Java 7.
FMW releases are big and complicated. Between the main FMW releases, Oracle release some products on separate “branches”. This is to fast track new features.
ADF 11g Release 2 is such a fast track product. The latest ADF 11g release 1 version is 184.108.40.206 and the latest release 2 is 11.1. (more...)

There are lots of ways of building ADF applications, so there is a very large number of possible architectures. I’ve found that three good architectures are:
In a simple architecture, you build the entire application in one workspace. Business components go into a model project in the (more...)
With JDeveloper 12c (12.1.2) Oracle added some great updates to the ADF EJB / Java Facade Datacontrol. Oracle already added the Java Facade and Named Criteria support in its previous versions of JDeveloper but now also added the so wanted List of Values feature, just like we have (more...)
One of the great features of ADF is the easy out-of-the-box support for Partial Page Rendering (PPR) using the partialTriggers, autoSubmit and partialSubmit properties. And when things get a bit more complex there is a very easy API to do it programmatically. But what if
Next week, I’m off for the OUGN Spring Conference that the Norwegian Oracle User Group arranges on board a cruise ship sailing from Oslo to Kiel and back. This event gathers the Oracle A-List, including Tom Kyte, Cary Millsap, Bryn Llewellyn, Mark Rittman, Markus Eisele and many others – it’s (more...)
Here one day before deadline, I have entered almost my entire current catalog of presentations for consideration in the Oracle OpenWorld 2013 agenda. One new for this year: “Worst Oracle ADF Project Ever”
If you would like me to speak at one of your events, the following are the presentations (more...)
I recently had to upgrade a WebLogic Server with ADF for a customer. It was WebLogic 10.3.4 to 10.3.6 and ADF 18.104.22.168 to 22.214.171.124. They also used Enterprise Manager.
Everything went fine except for the Enterprise Manager which ended up (more...)
With the IdentityStore framework of Fusion Middleware you can change or create any user or role in almost every LDAP server. With this framework the authenticated user change their own password from ADF or in your own ADF Admin page you can create an user with its roles without knowing (more...)
In the current version of ADF Mobile the ADF DataControls ( URL and WS ) only supports SOAP and JSON-XML. But this does not mean we cannot use JSON. To handle JSON we can use the RestServiceAdapter
classes. The RestServiceAdapter will handle the Rest Service and JSONBeanSerializationHelper helps (more...)
This years visit to Oracle Open World is for me the best of both worlds. First of all I get to attend one of the biggest, if not the biggest, IT conferences in the world. Second, I have two presentations. Both are on Sunday afternoon. The first one is a (more...)
This blog post is a follow up to the previous one about modularity in Oracle ADF.
Sample applications provided in a blog posts are simplified focusing on one or few aspects described.
Real world ADF applications and task flows can be more sophisticated:
