Create a Custom ADF Component

During UKOUG Tech14 in Liverpool, Wilfred and I had a presentation about how to create your own Custom ADF Component. Since we were busy on preparing the presentation there were no blogs about these beforehand.
I thought it would be nice to give a small recap, for anyone interested in going into creating Custom ADF Components.

In our sample application we created an ADF Component called ‘multi select’ which offers the user the ability to (more...)

JDeveloper Debugging Tips (Watchpoints & Beep)

In a previous blog post I talked about scoping breakpoints for debugging purposes, next to scoping breakpoints JDeveloper has more interesting debugging features to offer.

I created a simple example to show both the watchpoint as well as the beep functionality. To illustrate this, I created a page with an inputText and a button, both bound to a backingBean. 

This  is the jsf code:
 



The code from the bean is also pretty straight forward:

OOW14 summary: Oracle ADF

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...)

What I learned at Oracle Open World 2014

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:

OOW14 summary: Oracle Service Bus

Since I am fairly new to the Oracle Service Bus I gathered a lot of information about this product. Most of it is not shocking and has been mentioned already, but this gave me a nice summarized overview of what 12c has to offer in comparing to 11g.

Since the 12.1.3 release, you don’t need eclipse anymore to create your service bus projects. Just as for the SOA Suite you can do (more...)

ADF EMG XML Data Control version 1.0.0

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:

ADF EMG Audit Rules moved to Atlassian

For those contributing and using the ADF EMG Audit Rules extension, this is now moved to the Atlassian Suite. Here we have better integration and more modern tools than on java.net.
Big thanks to Wilfred for helping me out with the conversion.

Make sure to save/bookmark the following links:
- Bitbucket
- Confluence / wiki
- Jira
- Bamboo

The old svn repository on java.net is deleted and you can now use git (more...)

ADF EMG Audit Rules available on JDeveloper 12.1.3

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:

Presentations at Oracle Open World 2014

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...)

Use tree binding accessors to show detail rows

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.

Access your MDS-SOA repository from your ADF application

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...)

Disabling and Enabling the Auto Map for XSL

When working with more complex XSL files, it can sometimes be useful to disable the Auto Map option. This can easily be achieved in the Auto Map Preferences popup you get when drawing lines in the design view of an XSL Map.


However, once disabled, you will not get this popup anymore to re-enable the Auto Map option. You need to do this through the Tools -> Preferences menu in JDeveloper. On the bottom of (more...)

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...)

Share your source between projects

Normally we pack functionality into libraries and use this library to share the functionality. However, during development of several JDeveloper Extensions our goal was to have one shared java source between our JDeveloper 11g and JDeveloper 12c extension.
Off course we wanted the ability to easily develop, test, debug and run the extension, but we also want to share the java code to introduce reusability.

We accomplished this, by creating a separated ‘coresrc’ folder and (more...)

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...)

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...)

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...)

Manually clear your JDeveloper cache

Recently I’ve been working more and more with JDeveloper Extension Projects. When working with Extension Projects, you deploy to your target platform a lot. I’ve noticed that sometimes, your JDeveloper Platform gets confused with this and the extension you’re working on doesn’t load correctly.

For example, you deploy your extension to the target platform, you follow this deployment in the log file and you see it got deployed successfully. After this, you debug the extension (more...)

Distribute your Extension with an JDeveloper Update Center

If you created an extension project, you can share this with others by creating a zip file. However, there is a powerful mechanism in JDeveloper called Update Centers. This blog will show you how you create an Update Center to share your own Extension Projects.

I’ll use my workspace from this blog about Audit Rules as example. Step 1 is creating an bundle.xml within your Project source. The bundle.xml should like like this:
