install servlets Q.

Hi,
	I am new in servlet and Java Web server, from FAQ of Jigsaw, it
said "create a Jigsaw w3c.jigsaw.servlet.ServletDirectory to export it."
after create directory servlets under WWW directory. I am wondering how to
create "w3c.jigsaw.servlet.ServletDirectory", is it mean to create a new
class?
	Thanks.
