Improved JET Rendering in ADF

This post is supposed to provide improved solution for the approach described previously - ADF and Oracle JET - Integration Pattern with ADF Regions. Many thanks to John Brock, Product Manager for Oracle JET, for his proactive comments and suggestions.

I have changed it to JET rendering in ADF, instead of integration. Perhaps word 'integration' is too strong in this context. You should not mix two frameworks together, like trying to render data from (more...)

OOW15: New features in ADF 12.2.1

The whole stack of Fusion Middleware 12c  was launched just before open world. This means there is also a new, cooler and better version of Oracle Application Development Framework (ADF) out!

So what is new? To start with, the infrastructure, we can now use JDK 8 in ADF and (more...)

OOW15: Announcing Oracle JET

One of the most heard questions is what is the different from Oracle JET with Oracle ADF? Will the one replace the other? Or (more...)

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.

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.
