Re: [Re: RMI Problem]

[jana reddy <janareddy@xxxxxxxxxxxx>]

Hi Michael,
I tried with ur suggestion..The following are my RMI pgms...

1.AddServerIntf.java (Interface Pgm)
------------------------------------
import java.rmi.*;

public interface AddServerIntf  extends Remote
        {
                double add(double d1,double d2)
                throws RemoteException;
        }

2.AddServerImpl (Pgm that implements AddServerIntf.java)
========================================================
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;
        }
}


3.AddServer.java  (pgm that Registers RMI)
==========================================
import java.rmi.*;
import java.net.*;

public class AddServer
        {
        public static void main(String args[])
        {
         try
          {
                System.setSecurityManager(new RMISecurityManager() );
                AddServerImpl addServerImpl = new AddServerImpl();
                Naming.rebind("AddServer" ,addServerImpl);
          }
        catch(Exception e)
        {
          System.out.println(e);
        }
        }
}

4. AddClient.java (Client Pgm)
==============================
import java.rmi.*;
import java.net.*;

public class AddClient
{
  public static void main(String args[])
        {
         try
          {
                String addServerURL="rmi://" + args[0] +"/AddServer";

//   args[0] will contain IP address of my AS/400 server

                AddServerIntf addServerIntf = 
(AddServerIntf)Naming.lookup(addServerURL);
                System.out.println("The first 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(e);
        }
}
}

Mike,i tried with ur options also by giving the default port number as 1099
but still when I execute "AddClient" followed by IP address of AS/400 server
and two parameters ,I get a message saying

"java.rmi.NotBoundException : AddServer",
I am confused...wud u bail me out of this crunch situation..

regards,
harish
