Run ADF & SOA on the IntegratedWLS in separated domain

In JDeveloper 12c, it is possible to run SOA Suite on the InternalWLS, which is a great feature. However, once you have done this, your domain will be filled with SOA extensions. Meaning the server start up time will increase drastically.
When you do both ADF & SOA development, this can be annoying when you just want to run your ADF application and the IntegratedWLS is busy starting up the SOA domain. One way to (more...)

Stretch your table to full page

In a previous blog I mentioned dynamic stretching table height with the autoHeightRows property. However, I have noticed people are having more troubles with stretching the height of the table.

This time I will focus on stretching your table to fill the total page height. We start with a simple ADF table on the employee table, showing all employees. Although I have seen more complex questions, including regions and more components in the structure, it (more...)

The Real Future of Oracle Forms – Not the Demise of Forms! Response to LinkedIn Thred

There is quite a debate going around based on Simon’s linkedin post regarding the future of Forms; but when you read it you’ll see, he doesn’t actually talk about the future of Forms – he talks about the demise of Forms and its replacement with Oracle APEX. As someone who does believe in the future of forms, there are several things  I wanted to clarify.

Firstly, it mentions that despite the release of Oracle Forms 12c, Oracle (more...)

Clear ADF 12c deployment on Integrated WLS

Sometimes you want to cancel your Integrated WebLogic Server, however, if you do this while a deployment is currently going on, you might run into trouble. The log window will not tell you anymore than a remote deployment failed and that the Application can not be run:



You need to clear some directories in your JDevHome before the application deployment works again. Before clearing the directories, make sure you close JDeveloper.

ODTUG Kscope15 Review: It was the best of times, it was the best of times!

Last week AuraPlayer headed south to attend ODTUG’s annual KScope conference in Hollywood, Florida. It was very exciting to play many pivotal roles; serving as an ODTUG Board member, an Exhibitor, a 2 time speaker and an Oracle ACE Director. The event was definitely a highlight – I truly learned a lot and, of course, had a lot of fun.

With that being said, so much happened that it would be nearly impossible to provide an (more...)

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:

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.
