5.         return name;  
6.     }  
7. }  

package flex; public class JavaFlex { public String helloJavaFlex(String name) { return name; } }

2，remoting-config.xml

1. <?xml version="1.0" encoding="UTF-8"?>  
2. <service id="remoting-service" class="flex.messaging.services.RemotingService">  
3.   
4.     <adapters>  
5.         <adapter-definition id="java-object"  
6.             class="flex.messaging.services.remoting.adapters.JavaAdapter"  
7.             default="true" />  
8.     </adapters>

16.             </source>  
17.         </properties>  
18.     </destination>  
19. </service>
