Flex+J2EE实例（cairngorm+blazeDS+hibernate+spring） part4

\----add cairngorm

1.添加在libs 下 添加Cairngorm.swc ，此时，具备了cairngorm框架能力

2.运用cairngorm框架

2.1 在flex\_src 下创建如下文件夹 和 文件

2.3修改FlexJ2ee.mxml的启动路径

右键FlexJ2ee.mxml

3.配置项目
    3.1 将remoting-config.xml中的
    	 <destination id="hello">
    	        <properties>
    	            <source>
    	                com.Hello
    	            </source>
    	        </properties>
    	 </destination>
    删除
    
    3.2 在WEB-INF下 添加 flex-servlet.xml  对flex 消息进行管理
    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:flex="http://www.springframework.org/schema/flex"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xsi:schemaLocation="
    		http://www.springframework.org/schema/beans
    		http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    		http://www.springframework.org/schema/flex 
    		http://www.springframework.org/schema/flex/spring-flex-1.0.xsd">
    
    	<flex:message-broker>
    		<flex:message-service
    			default-channels="my-streaming-amf,my-longpolling-amf,my-polling-amf" />
    		<flex:secured />
    	</flex:message-broker>
    </beans>

3.2 在WEB-INF下 添加spring文件夹，并在底下创建3个配置文件
