Ran a client program that interacts with Java EJB on the server. The source code is quite simple:

// The next time Dynamo is started, your Account EJB will be available
// both locally and remotely. Its local JNDI name (for accessing the
// EJB from within Dynamo) is dynamoejb:/dynamoEJBContainer/Account,
// and its remote JNDI name is
// dynamoejb://yourHost:8860/dynamoEJBContainer/Account (assuming that
// Dynamo's RmiServer is running on port 8860).

// The following is an example of a standalone client program that
// accesses the EJB remotely:

import javax.naming.*;
import javax.ejb.*;
import java.rmi.*;

public class RemoteTest
{
    public static void main (String [] args)
        throws NamingException, RemoteException
        {
            String jndiName
                ="dynamoejb://localhost:8860/dynamoEJBContainer/Account";

            Context ctx = new InitialContext ();
            System.out.println ("got context");
            AccountHome home = (AccountHome) ctx.lookup (jndiName);
            if (home == null) {
                System.out.println ("couldn't find home. exiting...");
                return;
            }
            System.out.println ("got account home");
            Account a = null;
            int loopMax = 1;
            try {
                double start = System.currentTimeMillis ();
                for (int i=0; i<loopMax; i++) {
                    System.out.println ("going to create home");
                    a = home.create ();
                    System.out.println ("created home");
                }
                double end = System.currentTimeMillis ();
                System.out.println ("delta time for \"a = home.create ();\"= "
