Finally, i build a simple sample who works.
Then i include my entire old project in it step by step.
So, the main problem i think was due to a classpath eror.
Indeed, i have try a lot a thing in my project so include a lot of libraries
in the classpath.
No the problem is solved.
Thanks you for your help and answers.

Denez
