J2ME UDP socket聊天程序编程，有用的信息就给分
最近想写一个聊天程序，就是在手机上发送一条字符串通过pc端服务器到另外一个手机上，想用socket网络编程来实现，但是有没有做过相关的项目，网上资料也很少，请各位帮帮出出注意，和思路，谢谢:-)
[解决办法]
看看WTK里的networkDemo

如果是聊天这块的话，建议你去看看XMPP协议，XMPP协议是基于Socket连接的，现在的IM（即时通讯）一般都用XMPP协议来实现。

字符串怎么到pc上？在pc上做个web程序，通过手机访问它，相当于网上的聊天室。

楼主好熟啊
咋这么低调哩
[解决办法]
去找一个J2ME的开源IM项目，Lampiro.不过里面代码我基本看不懂。
[解决办法]
不能做到主动push消息，除非客户端自己请求服务器才能知道是否有新消息

即时通讯，以上问题都可以解决。
