Java APIs

I am having a problem where the call to, sock.setSoTimeout(1000*15), works great if a host accepts the connect,
but then doesn't respond quickly enough, and I get a 'Read timed out', exception. However, sometimes the host is
not reachable over the network, in which case the setSoTimeout has no effect, and I assume it is the OS that times
out the request. Is there a way to set the socket timeout to catch 'Connection timed out' exceptions?

The following program demonstrates the problem, where the first host responded to the connect but just sat there
not responding, and so the 15 second timeout worked. The second host is on the network, but doesn't respond to
connects and so it takes 3 minutes, 9 seconds to timeout. I am using Java 1.4.2_13

Thanks in advance.
