Remote Interface

Listing 9.2 CustomInterface.java

import java.rmi.*;
import java.util.*;

//Remote interface
public interface CustomInterface 
	extends Remote{
	
	//method used to get the list of products
	public Vector getList()
		throws RemoteException;
	
	//method called by clients to submit information 
	public String submit(Customer cm)
		throws RemoteException;
}

The above interface declares two methods:

The getList() method returns a Vector of items sold by the company. The submit() method takes a Customer object as argument and returns a string containing information related to the customer.
