问题1： 对MarshalException的介绍 public class MarshalException extends RemoteException A MarshalException is thrown if a java.io.IOException occurs while marshalling the remote call header, arguments or return value for a remote method call. A MarshalException is also thrown if the receiver does not support the protocol version of the sender. If a MarshalException occurs during a remote method call, the call may or may not have reached the server. If the call did reach the server, parameters may have been deserialized. A call may not be retransmitted after a MarshalException and reliably preserve "at most once" call semantics.

A MarshalException is thrown if a java.io.IOException occurs while marshalling the remote call header, arguments or return value for a remote method call. A MarshalException is also thrown if the receiver does not support the protocol version of the sender. If a MarshalException occurs during a remote method call, the call may or may not have reached the server. If the call did reach the server, parameters may have been deserialized.

就可以了
Serializable 是一个空方法标志接口 完全不需要你去实现他什么东西 java 语言本身已经很好的实现了序列化的功能
