I’ve been doing apex for about 7 years now, and along the way I discovered a few things that made my life as a developer a lot easier. I made a list of 5 things thar I wish I had known wen I just started. Those things will be explained to you in a series of 5 posts.

One of the most tiresome things to do when managing multiple applications is to keep things like (more...)

Developer Interview (#DI15) with Niko Köbler (@dasniko) Java EE and Node.js Performance

Developer interview Friday. Today it is my pleasure to welcome Niko Köbler (@dasniko). We meet a couple of times before and I love following his ramblings about JavaScript on the server side. I talked to him about why and how he came in contact with server side JavaScript in general and made him show a little more about his recent performance test, that he ran against RESTFUL backends (WIldFly and node.js). For (more...)

5 Minute JavaScript #7 Closures

In the previous blogpost we discussed a way to reduce the amount of global variables by using namespaces. Today, we will be looking into a different way to hide functions and variables.

If you are JavaScript on a regular basis (without being an expert) you might have heard about ‘closures’. While closures are becoming increasingly popular in other programming languages as well, JavaScript allows you to take them one step further.

Sometimes you want to run (more...)

Created the first version of the JavaFX Browser inside Oracle Forms

I created the first version of the JavaFX browser inside Oracle Forms.

It still needs some adjustments, but the first version can be found at https://sites.google.com/site/oraont/jxbrowser-bean


I created a Form with two java beans components. I added the JavaFX browser with a socket server to one component and I added a socket client to the other component. With the socket server I made it possible to communicate to the java browser.

Fronting Oracle Maven Repository with Sonatype Nexus

The Sonatype team have announced the release of Nexus 2.1.1 which is a minor update that now works with the Oracle Maven Repository.

I was going to write a bit up about it but Manfred Moser from Sonatype has already put together a blog and video on it:
With the new Nexus 2.11.2 release we are supporting the authentication mechanism used for the Oracle Maven repository in both Nexus OSS and (more...)

Red Samurai ADF Performance Audit Tool v 3.4 – ADF Task Flow Statistics with Oracle DMS Servlet Integration

We have integrated Red Samurai ADF Performance Audit Tool with Oracle DMS Spy Servlet. Integration is dynamic and doesn't require any extra configuration. It brings out of the box information about ADF Task Flow usage and performance. This means we are analysing from now on not only ADF BC performance data, but ADF Controller data also.

DMS Spy Servlet context is accessed in certain intervals and we are not only displaying DMS data, but storing (more...)

IBM Bluemix – Deploy your app the way you want

We recently upgraded our capability in the IBM public cloud. Before this new version you could build, test, and deploy apps on Bluemix by using open source Cloud Foundry technology. But now you have more choice bringing two new options as follows

Plug in Policies Into JBoss Apiman

The JBoss apiman project did just release 1.0.3.Final this week.  It's mostly a bug fix release, with just a couple of relatively minor improvements. One particular feature, that made it's way into the framework since I last blogged about it is the support for plugins. Those plugins can easily be added to the system in order to provide additional functionality.

Add Policies As Plugins
Currently the only functionality that can be contributed through (more...)

ADF BC Range Paging and REST Pagination

In this post I would like to explore and integrate two thing - ADF BC Range Paging and REST service pagination. It would inefficient to retrieve entire set of data in the REST service, ideally should be available option to specify number of rows and range number to fetch. ADF BC allows to query VO in Range Paging mode - SQL query will be constructed with row numbers, to query data in certain range of (more...)

Marcus Lagergren 20 years of Java In Review

We know each other since some years now. And I am very very pleased to see, that we finally could make it happen to have him speaking at JavaLand as a Keynoter. And what would be better for a JVM veteran than talking about this years anniversary: Happy Birthday Java!
Thank you Marcus, for taking the time!

I am looking forward to a beer or two at JavaLand! Follow his rumblings about dynamic languages on (more...)

5 Minute JavaScript #6 Namespaces

Last post we noticed that variables can easily be attached to the global scope. This isn’t a good thing. The more variables are linked to the global scope the more chance you have creating conflicts.

A great way to reduce the impact of your code on the global object is to define namespaces. We do this by creating one global object that we extend with extra modules which on their turn can be extended with new (more...)

Playing around with JavaFx inside Oracle Forms

Sometime ago someone asked me some questions about the Enhanced java bean. That java bean was based on the JDIC (java desktop integration component) of sun. The project of  jdic hasn't been updated for quite some time. So the java bean is getting harder to use.

So I was searching for a different solution, when I stumbled on JavaFX. I now have the following results:


This a JavaFX browser inside Oracle Forms. It now displays (more...)

ADF Faces 12c Components Demo and Test Automation

You might have noticed that I am working on a series of blog articles on using Selenium to automate testing of Oracle ADF applications. This includes work on a little framework to make this easier and a set of sample JUnit tests against the public Oracle ADF Faces 12c Components Demo.

Getting the Faces 12c Component Demo running with test automation had some challenges. I wanted to write them down here in case somebody wants (more...)

Byteman – a swiss army knife for byte code manipulation

I am working with a bunch of communities in JBoss and there is so much interesting stuff to talk about, that I can't wrap my head around every little bit myself. This is the main reason why I am very thankful to have the opportunity to welcome guest bloggers here from time to time. Today it is Jochen Mader, who  is part of the nerd herd at codecentric. He currently spends his professional time coding Vert. (more...)

Java 8 and Spring 4

On March 27, 2014, the Spring community was happy to announce the Spring Framework 4.0.3. The reason why is that it was the first release of the Spring Framework with Java 8 support. Since then, the Spring team worked very hard to provide major updates for the Spring Framework to be even more supportive towards Java 8. As of September 4, 2014, the Spring Framework 4.1 has arrived with even more support towards the Java (more...)
