I'm building a feed reader that's supposed to be run for long periods of time collecting feed data.  I've noticed that if I lose internet connectivity the application freezes.  Is there a way to tell if an application is 'online'?  The processing online() function apparently only works for applets running in a browser window.  I figure there are probably quite a few different methods for determining whether an application has access to the internet.  Before delving into the specifics of which line of code is causing the problem and working out a try ... catch routine, I was wondering if there are other methods ... or even an explicit try ... catch function I could run to check before the code attempts to connect and d/l more feed data.
