    For bootstrapping, the RMI system provides a remote object registry
	that allows you to bind a URL-formatted name of the form 
	"//host/objectname" to the remote object, where objectname is a simple 
	string name.For example, the following code binds the name "Rem" to a 
	reference for the remote object.
