RMI registry is empty after restart

Question

I am using this plugin (it's pretty cool).

Needless to say, I am an RMI novice. I followed the tutorials and was able to put together a sample application.

I do not understand though why every time I stop and restart my local RMI registry the remote objects that were bound to it just vanish. Is this normal behavior? I was under the impression that the rmi registry could be used as a persistence tool - so the contents of the registry should not vanish when the registry is stopped and restarted.

I am probably missing something very obvious but, again, I am new to rmi.

Any pointers appreciated!

Answer 1

By default the RMI registry does not persist information about the objects registered with it. Therefore, you need to register your remote objects each time the server starts.

As a matter of curiosity, what was it that led you to believe that the registry would somehow "remember" the objects that were last registered with it?

Answer 2

no need for a standalone registry. you can create a registry right in the server VM:

    Registry reg = LocateRegistry.createRegistry(1099);
    reg.bind("service", myService);
