求java聊天室（serversocket）原代碼

百度一下，想飛社區(qū)，在資源里有，在JAVA開發(fā)-JAVA實(shí)例分類下面，好像有兩個(gè)版本的聊天室，一個(gè)簡(jiǎn)單版本的，就是SOCKET（server-client）通訊，有個(gè)復(fù)雜版本的，聊天室功能比較完全。都是源碼+說(shuō)明文檔，你可以參考一下

跪求用JAVA編寫的udp聊天室，要在本機(jī)能運(yùn)行多個(gè)窗口，進(jìn)行群聊和私聊,最好還可以傳送文件··要源代碼

自己表寫了一個(gè)QQ項(xiàng)目 不能群聊

有遠(yuǎn)程控制,文件傳輸,發(fā)送表情等功能

數(shù)據(jù)庫(kù)是mysql

已發(fā)

(項(xiàng)目還需要dom4j的jar包, 你可以到網(wǎng)上下載)
