red5 运用（二）

继续使用应用一中的java文件，添加方法

public boolean appConnect(IConnection conn, Object[] args) {
		System.out.println(" 连接");
		return true;
	}
	public String change(String str){
			System.out.println(" 客户端调用服务器");
			return str.toUpperCase();// 传入的字符串转换成大写后返回
	}

?新写flex文件，测试实现情况：

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
			   xmlns:s="library://ns.adobe.com/flex/spark"

	<s:layout>
		<s:BasicLayout/>
	</s:layout>
	<fx:Declarations>
		
	</fx:Declarations>
	<fx:Script>
		<![CDATA[
