ServerSocket does not detect a disconnected client

Question

Hi,
I have created a serverscoket, which will accept 'n' number of clients and send data to all the connected clients.
And the server should detect when any client goes down or disconnected from network and give the appropriate message to the use that this particluar client has got disconnected.
I'm able to detect the disconnected client, when the client application is shut down properly (and the application closes the socket). But while the application is running, when the network card is unplugged, then my server is not able to detect this connection loss, and it continues to send the data to the client without throwing any exception.
Any help would really be greatly appreciated.
Thanks,
Hema

I Asume you don't mean the ServerSocket but the Socket the ServerSocket accepted, for this Socket you can try using
acceptedSocket.setKeepAlive (true);This may speed up the disconnection detection depending on the implementation of the keepalive mechanism.
But it then may be that the connection will be terminated, although the connection is only very slow.
You have to test out, what is better for your purpose.
