Registry Interfaces

The RMI system uses the java.rmi.registry.Registry interface and the java.rmi.registry.LocateRegistry class to provide a well-known bootstrap service for retrieving and registering objects by simple names.

A registry is a remote object that maps names to remote objects. Any server process can support its own registry or a single registry can be used for a host.

The methods of LocateRegistry are used to get a registry operating on a particular host or host and port. The methods of the java.rmi.Naming class makes calls to a remote object that implements the Registry interface using the appropriate LocateRegistry.getRegistry method.
