利用RemoteObject动态调用 FluorineFx 的服务器方法？？？

1.使用<mx:RemoteObject/> 调用一切正常

	 <mx:RemoteObject id="service" destination="fluorine"

		 source="FlexNet.ServiceLibrary.Sample">

		 <mx:method name="Echo" result="onResult(event)">

		 </mx:method>

	 </mx:RemoteObject>

	service.Echo(txtInput.text);

2.使用 RemoteObject 总是报错：
错误信息：customOperationHandleFault: faultCode:Server.Processing faultString:'Failed to locate the requested type *' faultDetail:'null'

var remoteOperation:RemoteObject = new RemoteObject();
remoteOperation.destination = "fluorine";
//remoteOperation.endpoint= "http://localhost:2747/Web/Gateway.aspx";
var op0:AbstractOperation = remoteOperation.getOperation("Echo" );

op0.addEventListener(ResultEvent.RESULT,customOperationHandleResult);
op0.addEventListener(FaultEvent.FAULT,customOperationHandleFault);

op0.arguments = "adag";
op0.send();



服务器方法：

namespace FlexNet.ServiceLibrary

{

    /// <summary>

    /// Fluorine sample service.

    /// </summary>

    [RemotingService("Fluorine sample service")]

    public class Sample

    {

        public Sample()

        {

        }



        public string Echo(string text)

        {

            return "Gateway echo: " + text;

        }

    }

}

配置文件：services-config.xml

<?xml version="1.0" encoding="utf-8" ?>

    <services>

		<service-include file-path="remoting-config.xml" />

    <!-- Custom authentication -->

    <security>

		<!-- A security constraint requires that a user is authorized before accessing a destination.

		Here you can declare security constraints globally. When several destinations 

		use the same security settings, you should define one security constraint in the 

		security section of the services configuration file and refer to it in each destination.

		<!-- 

		<security-constraint id="privileged-users">

			<auth-method>Custom</auth-method>

			<roles>

				<role>admin</role>

				<role>privilegeduser</role>

			</roles>

		</security-constraint>

		A login command must implement the com.TheSilentGroup.Fluorine.Messaging.Security.ILoginCommand interface

		or inherit from com.TheSilentGroup.Fluorine.Messaging.Security.GenericLoginCommand.

		

		You can use a login command without security constraints defined.
