I personally use Craig's way as well (or similar), but I think another way
which should work is if you set up an alias for your servlet with some file
extension, then you should be able to access your servlet by the name of a
file in your directory structure, same way you access static files. Then
relative links to static files from the servlet-generated page should be
relative to the path of the file you used as an alias for your servlet.

You can easily generate references to static resources in the
dynamic HTML code
that your servlet generates. The simplest way is to just create
URLs that
contain the absolute path on the web server to where those resources
live.
That way, the web server will serve them like any other file, and
the servlet
does not have to worry about it The only challenge is, how does
your servlet
know what directory the resources are stored in?
My approach to this is to define an initialization parameter for my
servlet
(for example, called "images.directory") that contains the directory
prefix on
my web site where the images can be found. Then, in the servlet, I
concatenate
this with the name of the image I want (for example), and that
becomes the
value of the SRC attribute on my IMG tag. If I ever need to move
the images to
a different directory, only one thing needs to be changed (the
initialization
parameter) -- I don't have to make any changes to the code that is
actually
generating the links.
