instantiations using RMI. This class also contains utility routines to publish a RemoteFileManager
for remote use, and to lookup a remote one for local use.
To make a RemoteFileManager
available to remote clients:
System.setSecurityManager(new RMISecurityManager()); LocateRegistry.createRegistry(Registry.REGISTRY_PORT); new RemoteFileManager().bind();
To create a local Dictionary
backed by a remote RemoteFileManager
:
Dictionary dictionary = new FileBackedDictionary(RemoteFileManager.lookup(hostname));
