RMI Connect Exception

Question

I have a client server application,
1) Server is running on a Linux Suse machine
2) Client is running on a Windows 2000 machine
I had been running this application for some time now, but now i started getting this weird problem.
When i try to run the client i get this exception below:
java.rmi.ConnectException: Connection refused to host: 127.0.0.2;
and im unable to bring up the client.

Answer 1

I'm inclined to doubt that a security policy error, especially on the client side, would given you such a general error. You't get an exception from the security manager instead.
The "connection refused" is pretty much always down to not having a listener running on the port you're trying to connect to.
Pinging uses a lower level of connection than TCP/IP so it doesn't tell you anything about ports being open. All it establishes is that the server's operating system is up and reachable.
On unix you can use netstat to check what ports are being listened to by what tasks, don't know if you can do that on Windows. There's a netstat but I haven't explored the options.
Agreed, it's probably not a problem with the code, it's more likely to be a problem with the scripts that start the server, or nameserver.
