RMI remoting Timeout for host disappeared
Hi
I am using RmiServiceExporter for RMI remoting on an application that needs to fail over.
When I pull the network cable out of the remote computer to test the failover, the call takes about a minute to fail with RemoteLookupFailureException (cause java.net.ConnectException: Connection timed out: connect)
Does anyone know a way to make it fail quicker than that?
The stack trace while it is waiting for the timeout is:

After the one minute timeout, I get:

I notice that it is possible for a timeout to be set on the socket classes but I can't work out how to influence that from my Spring config or anywhere else.
I thought about using this: http://forum.springframework.org/showthread.php?t=20127
...except that I only want a quick timeout in the cases where the host is unreachable. At other times, remote calls may legitimately take several minutes.
Any help would be much appreciated. Thanks
Paul.
