can I use stream to marshall objects without a communicator

Can I use stream to marshall objects without a communicator?
I do not like to create a communicator, because I use stream to marshall objects only.

No, it is not possible to use the stream interfaces without a communicator.

Thank you!
Another question:
Can I create several communicators without network support?

Just creating a communicator should not cause any network activity/access. That should only occur if you create an object adapter or use a proxy. If you plan to create the communicator only to use the stream interface I am not sure why you would need to create several though.

Thank you, I got it.:)
It's possible to create several communicators when using multi-language or inter-language at one machine node.

Communicators, even in the same process, are independent objects and there is no limit (other than operating system resources) to the number of communicators you can create (in a single process, or on the machine).

Thank you! This Problem is solved perfectly.
