thanks for your quick reply jaikiran. is it correct to use timertask for file change listeners from my ejb3 application ? i had already some problems with threads into my ejb application. i thought maybe there is some abstract class for listening configs into jboss. i could do this by timertask. thank you very much again. ____________________ Regards Paata Lominadze Magticom LTD.
