Am I missing anything? Any particular tips to avoiding the
OutOfMemory exception other than increasing the initial memory
allocation?

Increasing the maximum memory is a good way to avoid out of memory

all of this. Client and server are two different things, they don't
affect each others' memory. I'm wondering why you think they do.

You should have a test harness that you can test these programs
(server/client) independently. Including out of memory, so you're sur=

you know the limits of each one, and that those limits correspond to the
way you thought you designed the software.

I'm using JNLP. Am I misunderstanding? I thought the webstart set u=

one JVM to share memory for client and server objects.
Is this not the memory limit? Is there another parameter I'm missing?

<j2se version="1.5+" href="http://java.sun.com/products/autodl/j2se"
initial-heap-size="24m" max-heap-size="128m"/>

I have my local PC set up to act as both client and server. I also
have a test server and a live server.
I hit an out of memory condition when I tried to use a custom object
with stream cloning (ObjectOutputStream/ObjectInputStream).

It is obviously physically impossible for the client and server to
share memory. They are different machines. In the case where they're
on the same host, they're still different virtual machines.
