Hi, I'm using RMI. I have defined all public methods from the Data class (not implementation) in the Remote Interface. I can't extend from the Data class to my Remote server since the server must extend java.rmi.server.UnicastRemoteObject. Is it a good idea to put the server in the Data class??
No, since the Data class is used locally and remotely, it's better to use delegation. I'm applying an Adapter/Proxy pattern: a server class which extends UnicastRemoteObject, implements the DataRemote interface and pass method calls to a Data instance. In addition, the server class deals with remote lock/unlock.
