Sample code : //-- @Schedules ({ @Schedule(hour="*/1"), @Schedule(hour="*/3"), @Schedule(hour="*/6") }) public void timeOutHandler(){ if(currentHr % 1 == 0) //-- Check for hourly

One thing about EJB Timers is that they are by default persistent which means that when ever there is server restart the Timers will automatically be invoked with out calling them again. I have a requirement that these timers should be manually be started when ever server is restarted . For this I know we need to change some attribute in config XML which I don't know exact. Where do I need to change the attribute to set persistent=false . I am
