I am adding a 2 jpanel (CENTER AND PAGE_END) to another Jpanel that goes in a JFrame. There is a HUGE gap between the 2 panels (panneauDateDebut and panneauDateFin) that I would like to eliminate. I have tried to set them in different configurations (start/center, start/end, center/end) but without luck. How can this be done ?

Well for starters (and for enders, don't know if this is english or not): don't call setPreferredSize()! This is what is causing all your problems. Stop using that (forever in your life ~ bad sense of humour, don't take it harsh) and you will solve all your problems.
Try this instead:
