no, and I believe doing so it bad practice. use some OS controlled timer like cron to issue a HTTP call to your servlet. I once wrote a shell script that calls a http address on the local machine but cannot remember how ;) if you are using oracle then you can setup this timer thread inside the database itself. don't add a thread into your web application.
