My Oracle OpenWorld presentation “Mastering Oracle ADF Bindings: Advanced Techniques” is now available for download from the OpenWorld web site. In this presentation, I talk about
- Reading the Bindings tab
- Bindings in the ADF lifecycle
- Working programmatically with bindings
- Getting the binding from a component
- Working with dynamic bindings
- Creating a binding programmatically
If you are interested in creating bindings programmatically, you should read Eugene Fedorenko’s blog post on this. He also makes (more...)
This article describes how to standardize your JDeveloper Installation as requested in Planning & Getting Started – Team, Skills and Development Environments. It is part of the ADF Architecture Practice lessons and describes the installation with examples for windows.
In this version the Oracle Universal Installer allows the silent installation of JDeveloper. All what you need is the installer file for your platform (e.g. jdev_suite_121300_win64.exe) and a response file. You (more...)
Being an ADF developer, off course a lot of my focus and attention went to the ADF related sessions. I left OOW with a mixed feeling about the ADF sessions. On the downside I felt there was not a lot of attention for ADF during the OOW conference. You see ADF or ADF related features during almost all the presentations, whether it is the Cloud, SOA Suite and Service Bus or MAF, but not a (more...)
Oracle Open World was once again very inspiring, last week I’ve been summarizing my own notes. I decided to share them with the world, if not only for me to find them back in my own blog archive in the (near) future.
As you might have guessed, there was a lot going on about the cloud. So much, it was almost confusing. The most interesting clouds that stayed with me after OOW14 where:
Today at Oracle Open World
, we (Wilfred
and myself) officially announced the 1.0.0 version of the ADF EMG XML Data Control. Check out the presentation
on slideshare if you missed it.
You can get this extension through the JDeveloper Help -> Check for Updates menu. Make sure you select the 'Open Source and Partner Extensions' checkbox:
There you should see the 'ADF EMG Data Control' extension:
A brief description for those (more...)
I got a few questions from people why the ADF EMG Audit Rules are not available in JDeveloper 12.1.3. So there has been a new release of the ADF EMG Audit Rules. No new functionality is implemented this time, but the extension is now available for JDeveloper 12.1.3.
If you go to Help -> Check for Updates, tick the Open source and Partner Extensions checkbox and press Next:
Select the ADF (more...)
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
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...)
