A remote object registry is a bootstrap naming service that's used by RMI servers on the same host to bind remote objects to names. Clients on local and remote hosts can then look up remote objects and make remote method invocations.

The registry is typically used to locate the first remote object on which an application needs to call methods. That object then provides application-specific support for finding other objects.

The methods of the java.rmi.registry.LocateRegistry class are used to get a registry operating on the local host or local host and port.

The URL-based methods of the java.rmi.Naming class operate on a registry and can be used to:

•: Bind the specified name to a remote object
•: Return an array of the names bound in the registry
•: Return a reference, a stub, for the remote object associated with the specified name
•: Rebind the specified name to a new remote object
•: Destroy the binding for the specified name that's associated with a remote object
