Arnaud in Tunis : 

Also after I planned with the god maven maven Arnaud Héritier evening, he speaks of it here: 

" Bon, peut être pas si loin que ça :-).La semaine du 18 juin je serai au soleil en Tunisie ( pour le travail avec les équipes d’eXo platform évidemment !! ).A cette occasion je devrais être de passage au TnJug (La date exacte n’est pas encore fixée). Si vous avez des idées de sujets que vous voulez que j’aborde n’hésitez pas à m’en parler ci-dessous dans les commentaires et je ferai mon possible pour vous faire une session en adéquation avec vos envies. Vous pouvez retrouver tout mon catalogue de présentations sur slideshare. "

But it did not end because we have a lot of organizational problem.

Hot-swap with Dynamic Code Evolution VM

Introduction :

I am currently working in my business on a project that contains over thirty sub maven projects. To do programming very well, we have to use every minute a java debboger this is a good link to know how to debbug java program in eclipse). I have presented in this context, the dcevm framework, and it's pleasure to share this experience with all. 

First Step : What is  DCEVM : 

I found this definition in the Dynamic Code Evolution VM site 

The Dynamic Code Evolution Virtual Machine (DCE VM) is a modification of the Java HotSpot(TM) VM that allows unlimited redefinition of loaded classes at runtime. The current hotswapping mechanism of the HotSpot(TM) VM allows only changing method bodies. Our enhanced VM allows adding and removing fields and methods as well as changes to the super types of a class.

For me, it's simple to define DCEVM : 

Is a technique that allows to modify java source code without restart or redeploy your packaging.

Second Step : Installation: 

The installation is so simple : 
1. You should download the jar file from dcevm site, there are many jar package for windows, mac and linux :

• dcevm-0.2-win.jar (5.6 MB)
• dcevm-0.2-mac.jar (6.0 MB)
• dcevm-0.2-linux.jar (5.8 MB)

If you don't see your JVM version, you can get the sources and compil it to get the right version.

2. Now to lunch the installer under windows, you should write in command line the command : 

 java -jar dcevm-0.2-win.jar  

After this step, we will install the new JVM, to do this just click on install : 

3. To verify installation, you should turn application in debug mode.
