java.rmi.NoSuchObjectException: no such object in table

Question

I am writing a very simple RMI server, and I am seeing intermittent java.rmi.NoSuchObjectExceptions in the unit tests.

I have a string of remote method

I have the same problem and now I've solved it. The solution is simple, you MUST create strong reference 'object' to avoid the object being GC'd.

for example in your server class:

...
private static ServiceImpl serviceImpl = null;

public static void register (int port) {
    serviceImpl = new ServiceImpl();
    Registry registry = LocateRegistry.createRegistry(port);
    registry.rebind ("serviceImpl", serviceImpl);
}

public static void main(String[] args) throws RemoteException, NotBoundException {
    register(1099);    
    ...the rest of your code...
}

So, it protects "serviceImpl" object from being GC'd. CMIIW
