高手帮忙看一下：SocketException: Connection reset

[langqianqian]

在写一个聊天软件，先运行Server端以后，再运行Client端的时候出现
java.net.SocketException: Connection reset

Connection reset
连接已经断开。
看看Socket是否关闭

[langqianqian]

SOCKET关闭注了以后还是这样

[dbsshida]

有沒有寫個死循環執行recieve()方法來接收客戶端發起的連接?

[dz007]

socket关闭了自然就断开啦

只要有客户端断开就会报这个

楼主，代码啊~~

传代码怎么传啊
嘿嘿不好意思，我第一次发帖子
