Help!!getting Connection Exception &permission denied for my local system

Question

Hi,
I am getting this connect Exception when i am running my RMI program.It is not comming when i am running all the programs[server,client] in my local system.
When i put the server program in the server which is linux server and i am calling it from my local system its giving ConnectException permission denied to 127.0.0.1,no more further infoemation.
These are the programs..
server :
import java.net.*;
import java.rmi.*;
public class AddServer
public static void main(String args[])
     try
     AddServerImpl addServerImpl=new AddServerImpl();
     Naming.rebind("AddServer",addServerImpl);
     catch(Exception e)
     System.out.println("Exception :"+e);
Implement:
import java.rmi.*;
import java.rmi.server.*;
public class AddServerImpl extends UnicastRemoteObject
implements AddServerIntf
public AddServerImpl()throws RemoteException
public double add(double d1,double d2)throws RemoteException
     return d1+d2;
Interface:
import java.rmi.*;
public interface AddServerIntf extends Remote
     double add(double d1,double d2)throws RemoteException;
Client Program :
import java.rmi.*;
import java.rmi.registry.*;
public class AddClient
     public static void main(String args[])
     try
//     String addServerURL="rmi://"+args[0]+"/AddServer";
     Registry r=LocateRegistry.getRegistry("rmi://"+args[0]);
//AddServerIntf addServerIntf=(AddServerIntf)Naming.lookup(addServerURL);
AddServerIntf addServerIntf=(AddServerIntf)r.lookup("AddServer");
System.out.println("The firsrt number is"+args[1]);
double d1 =Double.valueOf(args[1]).doubleValue();
System.out.println("The second number is:"+args[2]);
double d2=Double.valueOf(args[2]).doubleValue();
System.out.println("The sum is:"+addServerIntf.add(d1,d2));
catch(Exception e){
     System.out.println("Exception:"+e);
Plese go thru it and tell what modifications that i have to do with it...
regards,

You can specify a policy file and grant the following pemission in it:
grant {
permission java.net.SocketPermission "*:1024-65535","accept, connect, listen, resolve";
Specify this policy file using "-Djava.security.policy=your policy file".
BTW, don't forget to run rmiregistry before you launch your own RMI application.
Good luck!
