java.rmi
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()
.
