   1.1  实践描述

   服务器提供个人信息资料库（HashMap），客户端通过姓名来进行调用查询，预期返回该个人属性集对象（Properties）。主要是介绍RMI的具体应用和远程接口函数值的返回。

   1.2  实践过程

   1.2.1  远程接口定义

public interface Personal extends Remote
{
//-------------------------------------------------------------------------
//Get personal info. by name
 public Properties getPersonal(String __name) throws RemoteException;

   1.2.2  定义服务端执类

public class PersonalImpl extends UnicastRemoteObject implements Personal
{
//Personal info. container
 private HashMap m_infoMap;
//-------------------------------------------------------------------------
 public PersonalImpl() throws RemoteException
{
m_infoMap = new HashMap(100);
//Append personal info. records
  addPersonal("Paul", "Male", "1980/11/20", "Travelling, Fishing, Programming");
……
}
//-------------------------------------------------------------------------
//Add personal info. to map container by name
 private void addPersonal(String __name, String __sex, String __birthday, String __hobby)
{
Properties props = new Properties();
//Set properties
  props.setProperty("name", __name);
props.setProperty("sex", __sex);
props.setProperty("birthday", __birthday);
props.setProperty("hobby", __hobby);
//Add to map
  m_infoMap.put(__name, props);
}
//-------------------------------------------------------------------------
//Get personal info. by name
 public Properties getPersonal(String __name)
{
return ((Properties)m_infoMap.get(__name) );
}
