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

Answer 1

Got the same error but probably for the other (yet unknown) reason.

I was casting exported object to the type of my remote interface and then while binding to name I was getting NoSuchObjectException. Removing casting fixed the problem.

Briefly:

public interface MyRemoteInterface extedns Remote {
    ...
}

public class MyRemoteObject implements MyRemoteInterface {
    ...
}

public static MyRemoteObject obj = new MyRemoteObject();

public static void main(String[] args) {
    //removing cast to MyRemoteInterface fixes the problem
    this.obj = UnicastRemoteObject.exportObject((MyRemoteInterface) this.obj, 0);

    //unless the above cast is removed, this throws NoSuchObjectException occasionally
    LocateRegisry.getRegistry("127.0.0.1", 1099).bind("name", this.obj);
}
