I have a server running on rudra.eng.sun.com, as well as a registry at port
10099. When I try to invoke a method on a Remote reference obtained via a
registry lookup from ohio.central.sun.com, I get an unknown host exception for
the server host. Somehow RMI loses the domainname when making the newServer
remote call.

- jre1.1.5/bin/jre -cp .:jma.zip xDomain rudra.eng.sun.com
local host is ohio

test case follows. to duplicate, one will have to replace JmaDispatcherRmi...

import java.rmi.*;
import java.net.*;

import com.sun.em.server.jma.JmaDispatcherRmi;

public class xDomain extends java.applet.Applet {

    public void init() {
    }

    public void start() {
        String hostname = getCodeBase().getHost();
        connectTo(hostname);
    }

    public static void main(String[] args) {
        if (args.length < 1) {
            System.err.println("Missing argument: hostname");
            return;
        }
        try {
            String localhost =
                java.net.InetAddress.getLocalHost().getHostName();
            System.out.println("local host is "+localhost);
        }
        catch (java.net.UnknownHostException e) {
            e.printStackTrace();
        }
        
        String hostname = args[0];
        connectTo(hostname);
    }

    static void connectTo(String hostname) {
        String serverName = "rmi://" + hostname + ":" +
            Integer.toString(10099) +
            "/managedObjFactory/JmaDispatch";
        System.out.println("looking up "+serverName);
        try {
            JmaDispatcherRmi remoteObj =
                (JmaDispatcherRmi) Naming.lookup(serverName);
            System.out.println("looked up "+remoteObj);

            System.out.println("creating new server "+hostname);
            String newSrvrName = remoteObj.newServer(hostname); <<-- fails
            System.out.println("created server "+newSrvrName);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
