AS3无法从Java发送的套接字解​​码AMF3对象

我有一个java套接字服务器,它在连接时将Animal对象发送到Flash客户端.
对象发送方式如下：

Amf3Output amf3Output = new Amf3Output(SerializationContext.getSerializationContext());
amf3Output.setOutputStream(userSocket.getOutputStream());
amf3Output.writeObject(animal);

闪存方面的代码是：

var object:Object = socket.readObject();
trace(object);
trace(object as Animal);

但是,当第二个跟踪给我一个null

我检查过java发出31个字节,Flash接收31个字节.

我认为可能是我的Java和AS3类与某些AMF要求不匹配.

Java类：

package main;

public class Animal {

   public String name;
   public int age;
}

AS3课程：

package  
{

    [Bindable]
    [RemoteClass(alias="main.Animal")]
    public class Animal 
    {
        public var name:String;
        public var age:int;

    }

}

解决方法:

我不熟悉Java和可用的AMF序列化器/反序列化器,但是在闪存中确实支持通过套接字发送类型化对象,并且如果发送正确的数据则可以正常工作.下面是ruby与Flash应用程序通信的套接字服务器的示例.我正在使用RocketAMF在连接后通过套接字将AMF3对象发送到客户端.

SocketTest.as：

package {
    import flash.display.Sprite;
    import flash.net.registerClassAlias;
    import org.rackAMF.*;
    import flash.net.Socket;
    import flash.events.*;

    public class SocketTest extends Sprite {
        private var socket:Socket;

        public function SocketTest() {
            registerClassAlias('Animal', Animal);

            socket = new Socket();
            socket.addEventListener(ProgressEvent.SOCKET_DATA, onResponse);
            socket.connect("localhost", 8081);
        }

        private function onResponse(e:ProgressEvent):void {
            var animal:Animal = socket.readObject() as Animal;
            trace(Object(animal).constructor); // [trace] [class Animal]
            trace(animal.name); // [trace] Zebra
            trace(animal.age); // [trace] 5
        }
    }
}

class Animal {
    public var name:String;
    public var age:int;
}

socket_server.rb：

require 'rubygems'
require 'socket'
require 'rocketamf'

class Animal
  attr_accessor :name, :age
end

# Map "Animal" in ruby to "Animal" in flash
RocketAMF::ClassMapper.define do |m|
  m.map :as => 'Animal', :ruby => 'Animal'
end

server = TCPServer.open(8081)
loop {
  client = server.accept

  animal = Animal.new
  animal.name = "Zebra"
  animal.age = 5
  client.write RocketAMF.serialize(animal, 3)

  client.close
}
