Answer 1

when you want to connect to remote server with RMI you must add a system property same as:

System.setProperty("java.rmi.server.hostname","Ip or DNS of the server");

or add environment variable.

For me I got Connection Refused and solve it by adding this line of code in server side:

 java -jar -Djava.rmi.server.hostname="ip or dns of the server" packageName.jar

Thank to other guy for guide me to solve it.

Answer 2

PROBLEM SOLVED

I had exactly the same error. When the remote object got binded to the rmiregistry it was attached with the loopback IP Address which will obviously fail if you try to invoke a method from a remote address. In order to fix this we need to set the java.rmi.server.hostname property to the IP address where other devices can reach your rmiregistry over the network. It doesn't work when you try to set the parameter through the JVM. It worked for me just by adding the following line to my code just before binding the object to the rmiregistry:

System.setProperty("java.rmi.server.hostname","192.168.1.2");

In this case the IP address on the local network of the PC binding the remote object on the RMI Registry is 192.168.1.2.
