Live ref object Object ID at transport layer in RMI

[Naseem Khan]

Hi...

On the server side, when the server object is created, the constructor of UnicastRemoteObject performs an exportObject(). Inside exportObject(), an UnicastServerRef object is instantiated and exported. It creates a live reference object (the transport layer) which contains an IP address, a TCP port number and an Object ID.

From some article i read this.

Then a mapping from the Object ID to the stub and skeleton is registered in an object table residing in the transport layer.

Could nyone plz tell me wat is this:
1.Live reference object
2.Object ID
How it relates to stub and skeleton and wat is this mapping?

I searched a lot in UnicastServerRef class's exportObj() method, it further defines some Target class object. In fact i searched all this in Util class then WeakClassHashMap, WeakHashMap, then SoftReference...But i did not understand Object ID , live reference object etc.

Any suggestion will be appreciated.

Tx in advance

Bye
