folks,
does corba support object behaviour to be transported on the wire. I read lot of notes mentioning IIOP does not and RMI does.
But if I am not wrong, latest version of CORBA/IIOP supports objects to be transported (behavior).

please clarify.

thanks,
suekar !

NO. RMI / IIOP does supports. Please recheck with docs.

- RMI over IIOP does not, (I did not hear about "latest version of CORBA/IIOP supports")
- RMI over JRMP does transport behaviour.

Starting with CORBA 2.3, pass-by-value is supported, and applications can
therefore transfer objects from the server to the client by copying. Prior to version 2.3, CORBA only supported remote references, and the lack of object transferring was seen as a major disadvantage.

Following is my understanding, after reading the javaworld's article sited in this discussion.

1. Transfer behaviour means pass-by-referance (If you pass a distributed object, actualy its stub will be sent)
2. Transfer state means pass-by-value (in otherwords passing a replica)
3. (1) and (2) are supported in RMI over JRMP
4. (1) and (2) are supported in RMI over IIOP
5. Only pass-by referance is supported in IIOP (before CORBA 2.3)

Please correct me, if I am wrong.

Thanks
