thks a lot for ur response, two years after ;) I'm trying actualy , a little bit the same way , but for moment with db provider. I was also thinking about JbossCache as I use it in other parts. I was wondering what is the goods and bads between JbossCache and a database . One good point for database, is that all tasks are persistents, but when one node is broken, the order node take only the tasks which contains a date after the actual date, lets see my sql request I used in MySql: SELECT target, method_name, method_signature, start_date, period, repetitions, date_format FROM Schedule where start_date>NOW() Nice trick ?! How do you make that with JbossCache ? do u take all task in cache and look at the date parameter if it is superior ?? and how do you "clean" the cache with executed tasks ?
