Hi Don,
The maps are being generated in two scenarios. The first is a thick client
application which generates MapBeans in a standard Swing component. The
second is a JBoss server deployment, which is accessed by the client using a
web browser.
We're having problems in both scenarios where each map displaying CIB
imagery will take up about 400MB of heap space. This causes the app/server
to quickly run out of memory. This is a concern because the server will
obviously be aimed at hosting several users, with the potential of
generating several maps.
Thanks in advance,
Chris

Hi Chris,
Can you describe your architecture a little more? What's running on
your client, and what's running on your server?
