Thanks for your demonstration, I'll try that as soon as possible and will surely tell you what it did for me .. as far as i see it, the only thing different is inside the spring configuration file ..
i hadn't declare the DAO the same way .. I'll try your way and tell you what it changed.
Thank's for your answer.
I don't know if it was a bug in older version .. but as you were using the "abstract" attribute of bean element, I noticed that i was using spring 1.0.2 and not spring 1.1.
I tested with your declaration and spring 1.1 and it worked fine.
Thank you very much !
