This is handled by the JSP container, i.e. on the server side.

The path is hence relative to the JSP application.

css is not JSP includes, but is part of the plain webbrowsing, i.e. handled
from the *client* side.

css is "requested for" by the the browser, i.e. the path is relative to the
visible url.

I hope I have.

ok, I see.. "relative" meaning it can't be an abs. path starting @ root
of app? I mean a path like /inc/style.css is relative, whereas this
<webapp>/inc/style.css is absolute???

reason all this arose 4 me is that I have a var declared in one include
and it's used in another include used by same pg (but that is called
AFTER the include that contains var-declaration..) and get "can't find
symbol".. and I don't get this....

what I mean:

<%@ include file="/training/top125/past-winners/inc_top.jsp"%> --
var-declaration. var here..
<%@ include file="/training/top125/past-winners/inc_paragr.jsp"%>
<%@ include file="/training/top125/past-winners/inc_pg_nav.jsp"%> use
var here.. (get error on var: can't find symbol)
<%@ include file="/training/top125/past-winners/inc_table_top.jsp"%>

??? :( this is very weird....

thank you very much for your help..

Both your examples were "relative", but from different contexts.

JSP directives (those starting with "<%@") are dealt with and resolved by
the JSP container, on the server, where the path always is relative to the
JSP-application.

HTML directives (e.g. "<link" when "including" a style sheet) are dealt with
on the client side, which can use both relative and absolute paths. Relative
paths are in this case resolved by the webbrowser at the client side, with a
leading "/" the path starts at the "web root". Absolute paths in this case
starts with "http://"...

This rather sounds like something else, not related to the issue of "file
paths", as it seems that the "includes" themselves worked. The message hence
refer to another error, e.g. that the variable is defined in a way that it
later isn't recognized, like different spellings, scope constraints, etc.
