Does this look ok?
interface DB - provided by Sun
class Data implements DB - provided by Sun
interface DataClient - will have all the methods of DB, except lock/unlock
class DataAdapter implements DataClient - threadsafe wrapper class for Data. holds an internal reference to a Data object, wraps modification calls between lock and unlock calls.
interface DataRemote extends DataClient, Remote - the remote object
class DataRemoteImpl extends
, implements DataRemote
class DataConnector - client-side class that determines whether to return a new DataAdapter instance (for local mode), or a reference to the existing remote object (for network mode)
class DataRemoteObjReg - creates and registers the remote object on the server.
Does this look ok? I've never done RMI before, or anything network-related for that matter. It's kinda confusing for me.
