dynamic class loading

Hi all, Im trying to make a client and a server. The server should be
able to take "Classes" from the client, run them and return values back
to the client. Also eventually I would like to distribute the code to
multiple servers so they can all work on a portion of the problem, and
return there values to the client.

I need some opinions... is Dynamic class loading a better way to do this
than RMI? Does anyone know of a good tutorial that can start me off
with this?

Thanks

If the purpose is to solve a problem, focus on that instead of thinking in
terms of tranferring "classes" between the client and server. It is much
more likely that the most efficient way to solve the stated problem is to
tranfer data, not classes, between the servers and the client.

I want to know whether you have actually thought this through before fixing
on this approach.

Yeah. I think I have thought it through.

I want a situation where if 3-4 clients are connected to eachother, client X
can share a problem with the other 3. But the problem changes, it is up to
the clients to code and share the problem....I just want to create the
architecture to support this.

Whadda ya think? Am I off base with something? Shouldn't dynamic class
loading make this doable? Or do you think there is a better way

I think if this is the best, clearest description of the problem you can
provide, it is too soon to write code.

> ... client X can share a problem with the other 3.

Define "share". This is just one example -- this could mean anything.

That depends on what you are planning to do.

"That depends on what your planning to do"

Im planning to writing give an environment that connects clients, and allows
clients to share CPU time. I want to make the method as generic and as
possible to allow users to share whatever program they want.

Do you think RMI or Dynamic class loading is better for this? I am thinking
of simply sending the class file to the other clients and dynamically
loading it on the other side.
