During the ADF community event at AMIS Services last Thursday (22 may 2014), Wilfred
and myself announced a new upcoming open source project, named XML DataControl.
On the AMIS Live blog
there was a good summary about the functionality of the XML DataControl:
“The XML Data Control is an ADF Data Control that is used by developers to create data bindings in ADF Faces pages, just like the ADF BC Data Control and the (more...)
If you speak german and you are interested in quality assurance for your ADF projects you should come and attend my presentation at DOAG Development on 06/04/2014 in Dusseldorf.
I will show you, how you can implement in the JDeveloper IDE and in Continous Integration server Jenkins:
- static code analysis with PMD, FindBugs and Checkstyle
- Commit tests with JUnit, Mockito and Powermock for Mockito
- Code coverage for commit tests with JaCoCo
- Acceptance tests with JUnit (more...)
There is a new release of the ADF EMG Audit Rules extension. With this release there is now support for both JDeveloper11R1 and JDeveloper12c. However, remember that JDeverlop11g does not support the suppression of violations, so this may lead to a lot of violation on existing projects.
Remember that you can define a custom profile in the Audit tab under preferences to unselect certain rules, but off course it is better to look at the (more...)
Packt Publishing has a “buy one, get two” offer that runs until Wednesday. If you don’t have my ADF books, this would be a great opportunity to buy my new book Oracle ADF Enterprise Application Development – Made Simple: Second Edition and get a free copy of Developing Web Applications with Oracle ADF Essentials (or the other way around
Last Tuesday, March 18, there was an UX Event
organized by AMIS Services
together with the Oracle Applications User Experience Team. Between noon and 8 p.m. I visited a total of 13 sessions, 3 demonstrations and had a lot of great discussions, overall a great day and amazing event.
I picked up various things, from small tips and tricks to big lessons. Instead of keeping my notes to myself, I will try to give (more...)
In a previous post
, I explained how you can use the property 'autoHeightRows' to stretch a table. This is mainly useful in JDeveloper 11g, because in JDeveloper12c the stretching of tables is a lot better.
The main reason for this is that JDeveloper 12c sets the context-parameter Default Dimensions to 'auto' in the web.xml file:
The default value of this property (if not set) is not (more...)
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”.
Application usage displays the “long tail” characteristic: A few screens are used much more than others.
If you are re-developing your application, for example moving from Oracle Forms (more...)
In web development, a lot of times you want to avoid your browser caching messing up different sessions. Luckily most browser have some sort of an incognito modus now a days. I myself use Google Chrome the most while developing in ADF.
There is a command line start up parameter to start Google Chrome in incognito modus, a great feature in JDeveloper is that you can set these command line parameters.
If you navigate to (more...)
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.

Our use case was to have a table displaying data, with under this table some content. The content needed to be directly under the last table row. In ADF 12c this goes a lot better, but in ADF 11g, the table takes up some default space.
I recreated this on a HR example application:
ADF has a cool feature which can help in situations like this, it’s called ‘autoHeightRows’. In the documentation
of the (more...)
Over the last few weeks, I gathered and produced more and more info about Audit Rules, JDeveloper Extension Projects and other stuff related to creating Audit Rules.
I thought it might be wise to create some sort of an index page to refer to all these blogs, guides, articles and (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...)
Today at the UKOUG I showed a new plug-in for JDeveloper 12c together with Wilfred
, the ADF EMG Audit Rules. You can find it through JDevelopers Check for Updates in the Help menu. This plug-in is a starting point for creating rules out of the code guidelines document you (more...)
Here is my experiences with installing ADF 18.104.22.168.0 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 22.214.171.124 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...)
