Two questions are confusing me:
1. The remote client code that you write must provide all the public methods of the suncertify.db.Data class.
My understanding is for the local mode, the client will definitely implement all the public methods of suncertify.db.Data. But is this what this remote client refers to?
In network mode, the client will just make the connection with the rmi server and get a server handle and whenever client wants to do something with db on the server side, it just call the server method through the handle. Why should the remote client need to implement all the public methods of Data class? Why should the remote client care since the server already does this for him?
2.
Writing Data Client
To connect with your server,
you should create a client program. This implementation should include a class that implements the same public methods as the suncertify.db.Data class, although it will need different constructors to allow it to support the network configuration.
This talks about the same as implementing all the public methods as the Data class. I guess the remote client is probably the same as Data client. But I still don't get it why client needs to implement all the public methods as in Data class in remote mode. I understand the client needs to do that in local mode.
Could somebody have the same kind of questions and somebody else have different thought? Any comments are appreciated!
