<Content>使用session绑定就可以了
或者在数据库里放一个字段登陆后就修改成不可用
用户离开后改成可用</Content>

七点就上班了
还是干了一宿?

我刚把APLICATION搞明白
又出来个单县城

这个单县城与禁止相同身份同时在线是什么关系

虚心请教!</Content>

<Content>IP绑定就把IP加进APLICATION,
再判断不就行了么，
单线程，就是同一时间只有一个用户能访问，
你不能这样设定的，

我为你才新开一贴
我已经按你介绍的方法正常运行了
感谢

你再介绍一下IP绑定吧

用户名和密码是唯一的,
为什么还要判断IP那?

IP是这样获得的吗?
request.getServerName().toString();//得到服务器端地址。

又回到那个问题
一个用户登陆后
再以一同样的身份在另一台机器登陆,获得的SESSION是前一次登陆时的SESSION吗

<Content>在登陆时将当前的时间用.getTime()转化成微秒然/1000/60变成分钟存入数据库，并把数据库中用户状态设置成1，在此之前查检所以状态为1的用户中是否有现在时间.getTime()/1000/60&gt;5（说明此人已经5分钟内没有刷新过任何页)如果有经他的状态改为0，然后再用楼上的方法检查。再每页都将打开此页的时间转化成分，存入数据库！
可能乱了点，我的达表能力有限！
这个方法的缺点是，用户如果5分钟内不刷新任何页，就可以用相同的ID登陆了。或是用户死机，五分钟内他就不要再想登陆了！但我想用户又不知道这个密秘，应该没事吧，死机也得重启啊，怎么也得五分钟，呵呵
我是用这个统计在线人数，和显示人数列表的！</Content>

<Content>request.getRemoteAddr()返回一个String&#32;是本机地址要想得到服务器的地址:

import&#32;java.net.*;
public&#32;class&#32;catchserverip{
InetAddress&#32;ServerIPaddress=null;
//取得Server的IP地址
public&#32;InetAddress&#32;getServerIP()&#32;{
&#32;&#32;&#32;&#32;&#32;&#32;&#32;&#32;try&#32;{&#32;ServerIPaddress=InetAddress.getLocalHost();}
&#32;&#32;&#32;&#32;&#32;&#32;&#32;&#32;catch&#32;(UnknownHostException&#32;e)&#32;{}
&#32;&#32;&#32;&#32;&#32;&#32;&#32;&#32;return&#32;(ServerIPaddress);
}
}

就可以了
在jsp中写
String&#32;servername=catchipbean.getServerIP().getHostName();
