You can still use simple relative URLs. For example, in your servlet, you could
have:
out.println("<IMG src=/images/my_image.gif>");
This will refer to the base directory (the "/"), and then go the images directory.
You could also do something like:
out.println("<A HREF=../docs/my_doc.html>View Docs</A>");
So, if your URL to get to your servlet is
http://myserver.mydomain.com/servlets/MyServlet, the above URL will rewrite to:
http://myserver.mydomain.com/docs/my_doc.html
