If you're going to store it locally, and use that as a reference, you'll need to refresh it as regular intervals (perhaps through thread). The amount of time between refreshes is your window for the data to go "stale". Also note that you'll need to synchronize access to this list so that your servlets can access it (or not) while it is being updated by the server. But, all in all, "it depends" on your application whether this technique is appropriate or not.
