Swap space is basically a partition of the drive used for virtual memory. It usually gets used when the system is out of physical memory. To view all that info type this command:

# cat /proc/meminfo

You have no control over it, swapping is handled by the kernel. If you have a JVM with min 128MB and max 512MB, your talking about memory. If the server runs out of available memory, it's going to start swapping, but you'll have no control over which processes it does that to.
