I'm new to Java and RMI, but I'm trying to write my app in such a way that there are many clients connecting to a single server. So far, so good....
But when I close the server (simulating a crash or communication issue) my clients remain unaware until I make my next call to the server. It is a requirement that my clients continue to work without the server in an 'offline mode' and the sooner I know that I'm offline the better the user-experience will be.
Is there an active connection that remains open that the client can detect a problem with or something similar - or will I simply have to wait until the next call fails? I figured I could have a 'health-check' ping the server but it seemed like it might not be the best approach.
Thanks for any help
actually i'm just trying to learn more about RMI and CORBA but i'm not that far as you are. all i know is that those systems are also built to be less expensive, and as far as i know an active conneciton is an expensive thing.
i would suggest you use a multicast address to which your server sends somehow "i'm still here" but without using TCP connections, UDP should be enough for that purpose and more efficient.
