I don't know which operating system you are on but the JDK has a 
platform-specific management interface named 
com.sun.management.UnixOperatingSystemMXBean that allows the number of 
open file descriptors to be monitored. This isn't enumerating the open 
sockets so it might not be want you want. Personally I would use lsof or 
/proc to look at the target VM for information like this.
