flex通过blazeds与java通信的小例子

很简单的小例子，适合初学者理解
1，JavaFlex.java
package flex;
public class JavaFlex {
public String helloJavaFlex(String name) {
return name;
}
}

2，remoting-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<service id="remoting-service" class="flex.messaging.services.RemotingService">
<adapters>
<adapter-definition id="java-object"
class="flex.messaging.services.remoting.adapters.JavaAdapter"
default="true" />
</adapters>
<default-channels>
<channel ref="my-amf" />
</default-channels>
<destination id="firstJavaFlex">
<properties>
<source>flex.JavaFlex
</source>
</properties>
</destination>
</service>
3，testflex.mxml
<?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"

<fx:Declarations>
<!-- 将非可视元素（例如服务、值对象）放在此处 -->
<s:RemoteObject id="selectHello" destination="firstJavaFlex" fault="error(event)"/>
</fx:Declarations>
<fx:Script>
