step 1: 首先要确定RTMP的端口，可以利用netstat -an来查看

step 2: 修改services-config.xml，确保有rtmp的相关节点：

<channel-definition id="my-rtmp" class="mx.messaging.channels.RTMPChannel">
	<endpoint uri="rtmp://{server.name}:8323" class="flex.messaging.endpoints.RTMPEndpoint"/>
	<properties>
		<idle-timeout-minutes>20</idle-timeout-minutes>
	</properties>
</channel-definition>

step 3: 在网站新建apps目录，并添加MyChatRoom文件夹作为应用程序目录

step 4: 定义MyChatApp类继承自FluorineFx.Messaging.Adapter.ApplicationAdapter，并定义供客户端调用的方法GetResult()

step 5: 在应用程序目录(MyChatRoom)里添加配置文件app.config，内容如下：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
	<application-handler type="ServiceLibrary8.MyChatApp"/>
</configuration>

step 6: 新建Flex项目，分为 连接rtmp 和 调用方法 两部分来实现

服务器端：

using System;
using System.Collections.Generic;
using System.Text;
using FluorineFx.Messaging.Adapter;

namespace ServiceLibrary8
{
    public class MyChatApp : ApplicationAdapter
    {
        public string GetResult(string name, int age)
        {
            return name + "  is  " + age + " years old";
        }
    }
}

Flex端：

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
	<mx:Button x="211" y="69" label="连接RTMP" click="onConnectClick()" />
	<mx:Button x="190" y="113" label="调用RTMP提供的方法" click="onFunctionClick()" />
	<mx:Label id="lblResult" x="230" y="31" text="Label"/>

	<mx:Script>
		<![CDATA[
			import mx.rpc.events.ResultEvent;

			private var nc:NetConnection;

			private function onConnectClick():void
			{
				nc = new NetConnection();
				nc.connect("rtmp://localhost:8323/MyChatRoom");
				nc.addEventListener(NetStatusEvent.NET_STATUS, netStatus);
				nc.client = this;
			}

			private function netStatus(event:NetStatusEvent):void
			{
				var strCode:String = event.info.code;
				if(strCode=="NetConnection.Connect.Success")
				{
					this.lblResult.text = "连接RTMP成功!";
				}
				else
				{
					this.lblResult.text = "连接RTMP失败!";
				}
			}

			private function onFunctionClick():void
			{
				var responder:Responder = new Responder(onResult,onError);
				nc.call("GetResult",responder,"袁承志",20);
			}

			private function onResult(result:String):void
			{
				this.lblResult.text = "方法返回结果：" + result;
			}

			private function onError(event:Event):void
			{
				this.lblResult.text = "调用方法失败!";
			}
		]]>
	</mx:Script>

</mx:Application>
