本文介绍了一个名为AccountBean的远程接口的设计与实现细节。该接口提供了存款、取款等银行账户的基本操作，并定义了获取账户余额、所有者姓名及账户ID的方法。通过此接口，客户端可以与EJB对象进行交互，完成对银行账户的一系列操作。

package examples;

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

/**
* This is the remote interface for AccountBean.
*
* This interface is what clients operate on when they interact with
* beans. The container will implement this interface; the
* implemented object is called the EJB object, which delegates
* invocations to the actual bean.
*/
public interface Account extends EJBObject {

/**
* Deposits amt into account.
*/
public void deposit(double amt) throws AccountException, RemoteException;

/**
* Withdraws amt from bank account.
* @throw AccountException thrown in amt < available balance
*/
public void withdraw(double amt) throws AccountException, RemoteException;

// Getter/setter methods on Entity Bean fields

public double getBalance() throws RemoteException;

public String getOwnerName() throws RemoteException;
public void setOwnerName(String name) throws RemoteException;

public String getAccountID() throws RemoteException;
public void setAccountID(String id) throws RemoteException;
}
