/dev/null in a chroot

I chrooted apache to /www.

In order to run a java program from a web page, java needs a /dev/null
inside the chroot.

I don't want to create another whole /dev/ dir with all the disk raw
devices there to be read for anyone who cracks root.  I just want a
/www/dev/null file.

I tried creating a node with mknod exactly like the node in /dev but
it doesn't work in freebsd 6.  /dev/ is special now and you can't just
create nodes anywhere like the old days.

Is there a way to create a /www/dev/null which acts just like /dev/null?
