Hi ranchers,
My motivation comes from a problem in designing server-clients.If my client suddenly shut down while connecting server, my server need to get some information from such client.Should i use Unreferenced interface or some other classes?And how to use?

Unreferenced is only called when no client has a reference to the server. If you use the RMIRegistry, then it has a reference and Unreferenced is never called.

Your concern has been the concern of developers since the beginning of remote procedures. There have been numerous discussions on this subject on the RMI forum at java.sun.com. It all comes down to personal preferences.

My personal preference is: So What! I�m a Server. I�m here to service requests from remote clients. Because no clients call me for n-minutes, So What. If this is a big concern, then look into Activation. You can deactivate your server in times of no activity and reestablish it when next a client calls.
 
I agree. Here's the link: http://aspose.com/file-tools
