And again firewall issue... (but take a look, pls)

Question

I read posts here again and again, but didn't find an answer; situation:
1. my rmi-app works fine on local network;
2. i deployed Server-side of it on my web-server;
3. web-admin opened 2 ports (1099 & 3456) in server firewall;
4. server started;
5. client runs and binds server object
6. when trying to execute method, exception appears:
Connection refused to host: 127.0.0.1; nested exception is:
java.net.ConnectException: Connection refused: connect
I cannot understand why it wants to connect to 127.0.0.1 ???
Some server code:
Registry r = LocateRegistry.createRegistry(1099);
RmiImpl implementation = new RmiImpl("RmiImpl",3456);
RmiImpl code:
public RmiImpl(String name, int port) throws RemoteException
super(port);
try
Naming.rebind(name, this);
java.policy file on server:
grant
permission java.security.AllPermission;
running server: ./java Server
Client code:
java.rmi.registry.Registry r = java.rmi.registry.LocateRegistry.getRegistry(serverName, 1099);
// this works
myServerObject = (RmiInterface) r.lookup("RmiImpl");
// this is ok, too - I think I have pointer to server object now
myServerObject.getServerInfo();
// here I have Exception:
Connection refused to host: 127.0.0.1; nested exception is:
java.net.ConnectException: Connection refused: connect
any ideas, pls? I thought I almost reached final...
// and excuse my English

Answer 1

Your RMI server doesn't know its hostname or external IP address. Check your host file or whatever DNS configuration you use. If you can't fix that, set java.rmi.server.hostname at the server VM to the server host's external hostname or IP address.
