I am evaluating JBoss for possible use, and the question of memory footprint was brought up. We would 
need to to use Web Services, JAXB and JDBC data connections.

Is there a way to determine memory footprint as well as a ballpark for filespace requirements?

This would be on an X86 based Linux system (2.6.23 - like Fedora Core 8)

TIA,
