Problems with setting up rmi on two linux systems

For more information about how to set up rmi on two linux systems-Linux Enterprise applications-Linux server applications, see the following. Setting up rmi in two linux systems often causes the following exceptions: Naming. in lookup (url), the ip address of the url is clearly the ip address of the server, but the returned information is rejected by the local ip address. It is really weird. The exception is as follows:

Java. rmi. ConnectException: Connection refused to host: 127.0.0.1; nested exception is: java.net. ConnectException: Connection refused

The solution is to add a line of code to the server code:

System. setProperty ("java. rmi. server. hostname", server ip address); // Add this line of code
LocateRegistry. createRegistry (1099 );
RemoteImpl service = new RemoteImpl ();
Naming. rebind ("RmiServer", service );
