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.
