Announcement: ADF EMG XML DataControl

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...)

Quality Assurance for ADF projects

New release of the ADF EMG Audit Rules

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...)

UX – No Time To Kill

There’s no time to kill between the cradle and the grave
Father Time still takes a toll on every minute that you save
Legal tenders never gonna change the number of your days
The highest cost of livin’s dyin’, that’s one everybody pays
So have it spent before you get the bill, there’s no time to kill

ADF Book Bundle – get one free!

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 ;-)

What I learned from the UX Event

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...)

Web.xml parameter Default Dimensions

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:

oracle.adf.view.rich.geometry.DEFAULT_DIMENSIONS
auto

The default value of this property (if not set) is not (more...)

A Crazy Game Of Poker, Verse 2

A few months ago, I announced my resignation from EiS Technologies ("A Crazy Game Of Poker").  Another one of those leaps of faith - agreeing to part months ahead of time, not quite knowing where I was going next.  It's a great approach to parting ways with an employer if all parties can step up to behaving like grown-ups.  It gives the employer time to find and train a replacement as well as picking your (more...)

The Long Tail of Application Usage

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.

Long tail of app usage

If you are re-developing your application, for example moving from Oracle Forms (more...)

Start an incognito browser from JDeveloper

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...)

New publication for Oracle professionals

OTech Magazine Winter 2014If 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 Sorcerer’s Apprentice

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...)

Dynamic table height with the autoHeightRows property

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...)

Fusion Applications: Some Suggested Reading

I just finished a really nifty book:  Oracle Fusion Applications Development and Extensibility Handbook.  Required reading for anyone working with Fusion Applications.

The organization of the book is one of the reasons I highly recommend it.  The first four chapters lay out a foundation of knowledge need by anyone working with Fusion Applications in a functional or technical role.  The remaining 11 chapters provide deep detail (including instructions with pictures) on personalizing, (more...)

Index page for Audit Rules

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...)

14 for 14

So all the cool kids are sharing their predictions for 2014.  While I'm not much of a prognosticator, I thought it would be fun to share my own thoughts on the upcoming year.  If nothing else, we can all have a good laugh in 12 months over how poorly my (more...)

Extra Christmas Present?

Webservice interaction patterns – part 2 – Synchronous Webservice call timeouts

Goal: For reasons of performance and more importantly, good user experience, he client application (ADF) should be able to timeout gracefully instead of hanging indefinitely (and/or potentially causing STUCK threads on the ADF server) when invoking an external 'synchronous' web service.

At runtime
When I run the application,
If I (more...)
