Reference of remote (RMI)

[A Kumar]

Hi,

In a rmi program...the client is passing an object as a parameter in a remote method invocation...and in the server...

a copy of the object is created if am not wrong..


Is it true that any change i do of the object at my client side would cause the change of the same object at the server side or vice -versa...
server object changes and the same is reflected in the client ..object..

Thanks in advance,
Regards

Absolutely not.

As you said, a copy of the object is made on the server side. Changes on the server do not reflect on the client and vice versa.

It depends... are you passing a Seriailizable object as a parameter, or a Remote object as a parameter.

If you pass a Serializable - the server gets a copy - changes do not update.

If you pass a Remote - the server gets a stub - changes do update.

Hi Nathan,

I didnt get this...

It depends... are you passing a Seriailizable object as a parameter, or a Remote object as a parameter.

Can you be more clear about this...

Thank you...

Look at the introduction to section 2.6, 2.6.1, and 2.6.2 in the RMI specification.
