Triggering Dynamic actions from javascript code in APEX

Since APEX 4.0, dynamic actions have made our lives easier. But sometimes they feel a little restrictive in what you can do with them. Executing them upon the successful completion of another dynamic action, for example, or forcing a dynamic action to fire, triggered by something that happened in your javascript code.

APEX 4.2

Since APEX 4.2, there is a way to do this easily.

We start by creating the application process (more...)

How To Add New Operation in Oracle Mobile Suite Service Bus REST Service

I will use sample app from my previous blog post as the basis - Oracle Mobile Suite Service Bus REST and ADF BC SOAP. I was describing there the main steps in defining transformation from SOAP WS based on ADF BC to the REST WS interface. I will dive a little bit deeper into the same topic and will explain how to add new operation to the REST WS interface.

Using Code Snippets in JDeveloper

In JDeveloper, it can be helpful to set up code snippets to be of easy use later. Personally I use this mainly to set up code snippets for demo purposes and this is rather easy to set up.
First of all, if not already open, open your Components Window in JDeveloper: 

Now open the file that you want to create the code snippet from, this can be any file in JDeveloper as example I opened (more...)

You’re Cleverer Than You Think

I often train experienced developers in new tools, and I’ve found that most underestimate what they can do – their actual skill level is higher than their own perceived skill level.

Skill development

This is different from new developers, who tend to overestimate their skills.

The reason this happens to most experienced people is the “loss of control” feeling overcomes the feeling of accomplishment. If you are very skilled with one tool, you are acutely aware that (more...)

SSL with WildFly 8 and Undertow

I've been working my way through some security topics along WildFly 8 and stumbled upon some configuration options, that are not very well documented. One of them is the TLS/SSL configuration for the new web-subsystem Undertow. There's plenty of documentation for the older web-subsystem and it is indeed still available to use, but here is the short how-to configure it the new way.

First step is to generate a (more...)

Free Version Control Tool for PL/SQL is now available for download

We are pleased to announced that Gitora, the free version control tool for PL/SQL, is available for download.

Grails on Openshift

I created a simple Grails application which makes it possible to store client data inside a MySQL database. I created this application since I want to learn more about GORM (Grails Object Relational Mapping).

I already tested the application in the internal server from Grails, but I wanted to deploy it to a remote server. So I created a development account on Openshift and there I created the following server:

showPopupBehavior align property examples

I always struggle to understand the official descriptions for the align attribute of the af:showPopupBehavior tag. A picture is worth a thousands words so I just created screenshots of all the possible values:

afterStart: The popup appears underneath the element with the popup's upper-left corner aligned with the lower-left corner of the element. The left edges of the element and the popup are aligned


afterEnd: The popup appears underneath the element with the (more...)

Developer Interview (#DI 12) – Henryk Konsek (@hekonsek) about Camel on Docker

About WildFlies, Camel and Large Enterprise Projects

Just wanted to quickly publish my slides from the recent JDK.io talks about WildFlies, Apache Camel, Java EE and large enterprise projects.
Thanks to all the attendees for great questions and the attention.
JDK.io is the two day conference of the Danish Java User Group. The venue is pretty unique as it is the IT-University. Which is an amazing building and a unique atmosphere in the session rooms. Check out their website (more...)

5 Minute JavaScript #2 Scopes

In our last blog post we showed that JavaScript is different from Java when talking about functions. Another difference with regard to these object-oriented language lies in the code scope. Scopes are blocks of code in which a variable is known. It’s a context in which some variables are accessible, others are hidden, destroyed, etc.

In Object-Oriented languages such as Java, everything inside a  { } – pair is confined into a scope. For (more...)

Hardware is Cheap, Developers are Expensive

When advising customers on ADF projects, I often find development environments where many or all developers are working against the same database. That introduces a hard dependency between different parts of the project – if one developer deploys a defective PL/SQL package to the database, nobody else can run the application.

This approach made sense back when hardware was expensive and databases had to be managed by high priests in glass-walled, climate-controlled rooms. Today, you (more...)

Getting Started With OpenShift – A Quick Hands-On Introduction To OpenShift

Did you know, that there is a free ebook about OpenShift? Free, like in free beer? You’ll learn the steps necessary to build, deploy, and host a complete real-world application on OpenShift, without having to read long, detailed explanations of the technologies involved.
Though the book uses Python, application examples in other languages are available on GitHub. If you can build web applications, use a command line, and program in Java, Python, Ruby (more...)

DevNation – Call For Papers, Program Committee and Raising Excitement

DevNation Pictures from 2014
You have heard about DevNation before, did you? It is a 3-day technical, open source, polyglot conference for full-stack application developers and maintainers. The inaugural edition was held last year in San Francisco and delivered a promising start. You can find my trip report on this blog. While I've just been one among others in this incredible speaker lineup, the one things that changed for me working for Red Hat is, that I now actually (more...)

Developer Interview (#DI 11) – Stuart Douglas (@stuartwdouglas) about WildFly9 and Undertow

You know, that I am a Java EE guy. And I love looking into what comes up with latest servers. JBoss is working on WildFly 9 these days, and one particular area that always caught my interest is scaling, clustering and failover. So, this is a great chance to look at what the new version of Untertow will have to offer. And it is my pleasure to welcome Stuart Douglas to my developer interview series.

Reading MAF iOS Simulator Logging Output

It could be very handy to know how and where to read MAF logging output from iOS simulator. This is not that obvious to find logging output on Mac OS system. All log is written into application.log file, this file is located inside temporary application directory. I will explain how to locate this directory and how to open application.log file. You can read more about MAF testing and logging here - 18.5 (more...)

Kickstart on API Management with JBoss Apiman 1.0

The JBoss apiman project hit its first public milestone release (1.0.0.Final) recently, making it the perfect time to go out and have a look at it! Now that the first public release is out the door, we’re planning on iterating quickly on new features and bug fixes.  You should expect to see apiman community releases at least monthly.
