simply instanciate an runnable object in the init() of the servlet and
let this thread sleep for the desired duration, do its job and let it
sleep again. but make sure that you keep a reference to the thread
object in your servlet like:
init(...){
...
MyRunnable myRunnable=new myRunnble();
}
this prevents this object from being garbage collected (at least as long
your servlet lives ;)
also make sure to nullify the object in the destroy method of your
servlet.
if you want to avoid trouble with garbage collection and to start your
thread with server startup simply make your servlet preload.
