Is it possible to write a java application that basically periodically checks for updates for a particular piece of information in a web page? The web page in question like EBay and such uses user logins(sessions). For ex: say i want to track an auction in Ebay for a particular product.
Please tell me if there are any frameworks for doing this sort of a thing easily and also handle the session logins. And I am also open to the idea of implementing it in any other language like python too.
