Servlets in root - How do i configure

Hi,
	How does one map servlets in jigsaw. (something similar to
mappings.properties concept in jsdk)

Basically i have servlets which have to be referred as
http://server/servletname
I tried putting the servlets in the servlet directory.It works fine.
What should i do to put my servlets in the root directory and use them with
the above url
I am using Jigsaw for windows.

Can any one help me?
