For deployment// you may need a stricter security policy.//// For more information see:// http://java.sun.com/docs/books/tutorial/rmi/running.html// http://java.sun.com/j2se/1.5.0/docs/guide/security/PolicyFiles.html//grant {permission java.security.AllPermission;// Other options:// permission java.net.SocketPermission "127.0.0.1:1024-", "accept, connect, listen, resolve";// permission java.net.SocketPermission "localhost:1024-", "accept, connect, listen, resolve";// From http://java.sun.com/docs/books/tutorial/rmi/running.html// Copyright 1995-2005 Sun Microsystems, Inc.

Design Example:• In this example you will use Java RMI to create asmall distributed application. The application is asimple Domain Name Service (SDNS) that maintainsa table of (IP address, Domain Name) pairs.• The SDNS server is a service that maintains adirectory of (domain name, ip address) pairs. Aclient makes request of the remote SDNS serverobject using RMI. The SDNS protocol is defined byan interface that allows an SDNS client to performupdates and requests on a remote SDNS server.
