Java RMI

[Christopher Keah]

I got an issue running the java RMI tutorial on my macbook.
I can start the RMI registry the first time I run the server app.
But the 2nd and subsequent run, I get the following exception.

Unexpected exception

            ComputeEngine remote = REMOTE_COMPUTEENGINE;
            ComputeEngine stub = (ComputeEngine) UnicastRemoteObject.exportObject(remote, port);

            // register the remote object with the RMI registry
            Registry registry = rmiServerManager.getRmiRegistry(port);
            registry.bind(name, stub);

            LOGGER.debug("ComputeEngine bound");
        }
        catch (RemoteException ex)
        {
            LOGGER.error("ComputeEngine exception: " + ex.getMessage(), ex);
        }
        catch (Throwable t)
        {
            LOGGER.error(t.getMessage(), t);
        }

        while (running)
        {
            try
            {
                Thread.sleep(30000);
            }
            catch (InterruptedException ex)
            {
                // ignore on InterruptedException
            }

            LOGGER.debug("waiting...");
        }

It looks like the RMI registry is already running in the background or the port is never freed after the server application terminates.
Any ideas?

This answer doesn't help with your specific issue, but why are you trying to use RMI?

Its completely obsolete. See http://www.coderanch.com/t/570237/java/java/Why-there-still-interest-lots

Thanks.
I do understand that RMI is "blown glass" fragile.
I'm trying to get familiar with the protocol for an upcoming SCJD.

Best of luck on the test.

I do wish they would drop that whole topic. Would be better for all of us.

This tutorial attempts to appearance the aspect of RMI, after discussing any accidental features. Sun has provided a Adviser to RMI, but it includes a lot of actual that is not accordant to RMI itself. For example, it discusses how to absorb RMI into an Applet, how to use bales and how to abode aggregate classes in a altered agenda than the antecedent code. All of these are absorbing in themselves, but they accept annihilation at all to do with RMI. As a result, Sun's adviser is unnecessarily confusing. Moreover, Sun's adviser and examples omit a amount of data that are important for RMI.

There are three processes that participate in acknowledging limited adjustment invocation.
