Answer 1

Use this Server code -

Registry registry = null;
try {
    registry = LocateRegistry.getRegistry(52365);//use any no. less than 55000
    registry.list();
    // This call will throw an exception if the registry does not already exist
}
catch (RemoteException e) { 
    registry = LocateRegistry.createRegistry(52365);
}

Answer 2

If you're using macOS, you can stop port following as:

First thing you need to find the PID_number: lsof -i :1099

And then kill that port: kill -9 PID_number

Answer 3

Try this:

lsof -P | grep ':1099' | awk '{print $2}' | xargs kill -9

Answer 4

Re-check if the port 1099 is not used by any other process or user or start the rmiregistry on some other port.

Answer 5

The rmiregistry is using port 1099 in its process so you can't use it in yours. Either:

1. Start the registry in the same process, via LocateRegistry.createRegistry() (preferred).
2. Export your object on a different port.
3. Start the rmiregistry on a different port other than 1099.

Answer 6

Use ps -aef |grep rmiregistry. find the pid which rmiregistry use. Kill the pid Den run the server again...!!!!
