java调用ipmsg源代码

飞鸽传书（IP Messenger,简为IPMsg）是一个小巧方便的即时通信软件，它适合用于局域网内甚至广域网间进行实时通信和文档共享。特别是在局域网内传送文件/文件夹的速度非常快！

• IPMsg 是一款局域网内即时通信软件, 基于 TCP/IP(UDP).
• 可运行于多种操作平台(Win/Mac/UNIX/Java), 并实现跨平台信息交流.
• 不需要服务器支持.
• 支持文件/文件夹的传送 (2.00版以上)
• 通讯数据采用 RSA/Blofish 加密 (2.00版以上)
• 十分小巧, 简单易用, 而且你可以完全免费使用它
• 目前已有的版本包括: Win32, Win16, MacOS, MacOSX, X11, GTK, GNOME,Java 等, 并且公开源代码。

本文演示了如何使用Java的net包，向IPMSG客户端发送消息。

IPMSG收发数据包的格式（一行）：

<!--<br><br>Code highlighting produced by Actipro CodeHighlighter (freeware)<br>http://www.CodeHighlighter.com/<br><br>-->1version(IPMSG版本):no(消息编号，可以用系统时间):user(发送消息的用户名):host(发送消息的主机名):command(上述Command常量，可以用|组合多个值):msg(消息内容)

示例(向IPMSG发送消息，需要先打开对方的IPMSG)：
