I am proud to announce that I will be giving two presentation at Oracle Open World
this year in San Francisco. So some shameless self-plug on my blog to put them both under a little extra attention.
The first one will be on the ODTUG's and ADF EMG ADF Sunday, together with Wilfred
. We will explain and demonstrate our new open source project/product the ADF EMG XML DataControl
If you’re working with Oracle ADF and (more...)
I’ll be going to the UKOUG Tech 14 conference in Liverpool in December to give one of my favorite presentations: “APEX or ADF? From Requirements to Tool Choice”. I’m also leading the Development Tools roundtable, which is always lively at the UKOUG conference. If you want to discuss your options as a developer in the Oracle world, UKOUG Tech 14 is the place to be.
APEX or ADF? From Requirements to Tool Choice
Tree bindings can be very handy, for example to combine details in the same row as the master. Let’s assume we have the following starting point based on the HR schema:
We see the department in a form layout with navigation buttons, with a table under the form showing information about the employees. As you can see in the screenshot below in the ApplicationModule, there is also a Jobs detail under the EmployeeView.
If you (more...)
Some days before ZeroTurnaround has released XRebel , a new tool to recognized problems in your web applications, when you make your developer test.
This was promising, so I give it a short try for Oracle ADF applications. For this blog I use the Summit ADF application, delivered by Oracle, but I have tried with our own application too. Test is done in JDeveloper 12.1.2.
After the download there are some easy steps (more...)
In our Enterprise Landscape the SOA Services and our Canonical Data Model (CDM) live on a different WebLogic Server than our ADF application. But often we want to use these services and CDM in our ADF application.
Calling WebServices from an ADF application is not that difficult, however, we often want to manipulate the result that comes from this WebService. In 90 percent of the time, this are little adjustments to the existing CDM (more...)
Oracle ADF version 12c runs on JEE6 container Weblogic 12c. ADF Faces 12c (current version 12.1.2) is based on Java Server Faces 2.1 standard.
Version 2 of JSF introduced support for Bean Validation , as described in JSF specification ( Chapter 2.5.7). To summarize: it basically states, that java bean properties , annotated with Bean Validation constraints, are going to be validated
I have presented today on DOAG Development 2014 in Dusseldorf. For all non DOAG members – you can find the german presentation on slideshare too.

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...)
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...)
