Class Naming

java.lang.Object
  extended by java.rmi.Naming

public final class Naming
extends Object

The Naming class handles interactions with RMI registries. Each method takes a URL in String form, which points to the RMI registry. The scheme of the URL is irrelevant. The relevant part is:

//host:port/name

which tells the method how to locate and access the registry. The host and port are both optional, and default to `localhost' and the standard RMI registry port (1099) respectively. The name is simply a string used to refer to a particular service hosted by the registry. The registry does not attempt to interpret this further.

RMI services are registered using one of these names, and the same name is later used by the client to lookup the service and access its methods. Registries can be shared by multiple services, or a service can create its own registry using createRegistry().
