You want JAXB to unmarshal singletons? You already spent lots of time coding rather complex workarounds applying XmlAdapters and afterUnmarshal callbacks? The solution is astonishingly simple!

This page is for introducing Grizzly-Thrift server/client modules and sharing various benchmarking results.
Object serialization/deserialization of Java comes expensive. For improving this lack, we sometimes used to use other frameworks for RPC such as Protobuf and Thrift which support various programming languages, RPC and own data structures.
Especilally, Thrift has already provided various...

You know how nowadays everyone loves to tweet at conferences or presentations in middle of the talk? Sometimes you as a presenter might want to return the favor and tweet something in response. If you know upfront that what you are going to present will provoke a response from audience, you can now actually put the tweets in your presenter notes and have Keynote or PowerPoint to tweet on the...
As some of you already know. The next edition of JCertif is coming.
This year again the JCertif Conference will bring together developers from across Africa to learn, collaborate, and inspire each other.
This year, we're happy to announce 3 days of Java and Android training and 2 days of great talk, focusing on key areas where Java and open source are driving innovation: Java, Android, HTML5, JavaFX and JavaME.
The month of July was a global gathering for all Java Communities around the world to say "Hello" to Java 7.
JUG-AFRICA also hosted multiple events to celebrate Java 7 (see the photos below). I have traveled in Africa to give technical Java7 talks and met with hundreds of vibrant Java and Android developers. In Dakar, Senegal (July 7), Brazzaville, Congo (July 9) and Kinshasa, DRC Congo(July 10).

I know what you are thinking...consulting has always been a service. But the Cloud is making it evolve.
Cloud Computing has been one of my favourite topics in the last couple of years. Coming from a sysadmin background I am frequently in awe of how easy it is nowadays to conjure up vast amounts of computing and storage resources out of thin air. Of course I know that its not "out of...
Hibernate and OSGI Implementation Made Simple
Last April I kicked off FossESI to discuss how to take existing Java applications built using older technologies and implement them using new technologies like OSGi, Spring, Camel and NOSQL databases. At the time of the kickoff, we intended to begin comparing and contrasting 3 NOSQL databases. And just after that started, I got a real-life...

I've wanted to know how to do this for over a year. Not having the time in the past, well, the task just got delayed over and over. Now I finally figured this out, and I'm sharing with you. Surely there are other bloggers that prefer to use their own blog client and MarsEdit in particular if you're using an OS X client.
So, without further delay, here is how I set up my own MarsEdit client to...

In this short entry, I'd like to bring to your attention a nifty CMS engine built on top of JavaEE: flexive.

My 3 years old MacBook Pro went suddenly dead this week. Annoying as it is, this event allowed me to experience cloud computing like never before.
This notebook has been my main computer for the past 3 years. I used it for everything and carried it around wherever I went.
One day this week I was using it with tons of apps open as usual (I am known to never close anything...why do we have 4GB RAM...

JUG-AFRICA and JCertif 2011 honored in the first Java Magazine Premier Issue (Page 7) and I have published the first of a three part series of technical article in Java Magazine Premier Issue (Page 17) on how to build and deploy RESTful Web Services.

I'm used to find my name on my very own articles. But today I was rather excited when seeing myself cited on JavaWorld's web site.
