/**
* The <code>Naming</code> class provides methods for storing and obtaining
* references to remote objects in a remote object registry. Each method of
* the <code>Naming</code> class takes as one of its arguments a name that
* is a <code>java.lang.String</code> in URL format (without the
* scheme component) of the form:
*
* <PRE>
* //host:port/name
* </PRE>
*
* <P>where <code>host</code> is the host (remote or local) where the registry
* is located, <code>port</code> is the port number on which the registry
* accepts calls, and where <code>name</code> is a simple string uninterpreted
* by the registry. Both <code>host</code> and <code>port</code> are optional.
* If <code>host</code> is omitted, the host defaults to the local host. If
* <code>port</code> is omitted, then the port defaults to 1099, the
* "well-known" port that RMI's registry, <code>rmiregistry</code>, uses.
*
* <P><em>Binding</em> a name for a remote object is associating or
* registering a name for a remote object that can be used at a later time to
* look up that remote object. A remote object can be associated with a name
* using the <code>Naming</code> class's <code>bind</code> or
* <code>rebind</code> methods.
*
* <P>Once a remote object is registered (bound) with the RMI registry on the
* local host, callers on a remote (or local) host can lookup the remote
* object by name, obtain its reference, and then invoke remote methods on the
* object. A registry may be shared by all servers running on a host or an
* individual server process may create and use its own registry if desired
* (see <code>java.rmi.registry.LocateRegistry.createRegistry</code> method
* for details).
