refreshing data

[hopefulcharlie]

I have a jsp/servlet appilcation that reads a csv from the web and stores the data in the application session. I need a way of polling the source of the CSV once or twice a week and if the data has changed refresh it in my session. Can anyone advise me of the best solution?

you can create a class that will use threads and will run (as many times as you want) and check the file if its changed....
