Peter,
Is my understanding of the relationships between the Server object, Connection object and the Data object correct?
1, the Server is a connection factory, with the Data object as it's member variable (to keep it unique and pass its reference to all client connections)
2, the Connection object serves a single client, while accessing the shared Data object.
Thanks!
Jack

A single datasource does not necessarily mean only one table. If you allow multiple objects to open the same file, how could you provide record locking?

Thanks for the response! I still have the following question:
When a remote client lookup() a remote DataServer through RMI, (1) does it use the existing object (referenced by the jndi tree),
or (2) is a new object created ?
In case (1): the DataServer.finallize() won't be called when the client disappears, because the tree (and other clients) still have references to the object.
In case (2): how can multiple DataServer objects share a single DataObject?

Any comments on this will be appreciated!

To my understanding, all clients are sharing the same remote Data objet. How can you use unreferenced() to unlock a locked record when the locking client disappears, while other clients (and the jndi tree) are still holding references to the remote Data object?
