At four days of my birthday, my book about Java EE 5 has been published. Even if I wrote it own my own, it is a team effort. And I would like to thank my publisher Eyrolles, my friends who review the book while I was working on it (Zouheir Cadi, David Dewalle, Alexis Midon and Matthieu Riou), the Cnam University where I teach a Java EE course (Professor Jean-Louis Dewez of course but also all my students), the Community and my family who gave me the energy to write it. I let you discover more about its content.
