如何在Java EE中实现通用队列监视组件？

I'd like to create a queue monitoring container-managed component in a Java EE 5 app. The queue is a database table and every 5 mins or so the monitor would look for records that match certain criteria in that table. If there are any matching records, the monitor starts some kind of processing in a new thread. This sleep-check-do work loop should continue as long as the app is started and occur independently of any client session.I'd like to create a queue monitoring container
