接口 NameServerRemote

public interface NameServerRemote

A read-only name service. The name service provides hierarchical object lookup. The path names are separated by '/'.

Because the name service is hierarchical, a lookup of an intermediate node will return a NameServer instance.

The following example is a simple use of the NameServer:

 /dir-1/1 - where foo contains the string "foo-1"
 /dir-1/2 - where foo contains the string "foo-2"
 /dir-2/1 - where foo contains the string "foo-1"
 /dir-2/2 - where foo contains the string "foo-2"
 

The root server might have a URL like:

 http://www.caucho.com/hessian/hessian/name?ejbid=/
 

So root.lookup("/dir-1/1") will return the string "foo-1", and root.lookup("/dir-1") will return the NameServer with the URL:

 http://www.caucho.com/hessian/hessian/name?ejbid=/dir-1
