XMLSocket(服务器+客户端)代码,包含解决中文问题

//Flash code

System.useCodepage=true;
var mySocket:XMLSocket = new XMLSocket();

//本地地址，端口3000
mySocket.connect("localhost", 3000);
//事件
mySocket.onConnect = function(myStatus) {
 if (myStatus) {
  trace("连接成功!");
  //发送信息
  mySocket.send("发送中文"+"\n");
  trace("发送成功!");
 } else {
  trace("连接失败!");
 }
};
//接受信息事件
mySocket.onData = function(msg:String) {
 trace("接受到的内容:"+msg);
};

//Java code
