No, I can't. 1) I have no idea what your app is about or how it works 2) I don't want to take all the fun away from you!! Write a thread or something to poll the db and check for updates. You may need a versioning field or a tstamp. Alterlatively, have the app that DOES change the DB somehow inform your app. Perhaps via a messaging system. Then have your app remove appropriate portions from the cache. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4008397#...
