I'm doing JSP development, and I want something very simple. I want to
fontify the text between <% and %> tags, even if spread across multiple
lines.
How do I do this? I've tried regular expressions such as:
<%.+%>
<%\(.+\n\)+%>
and many variations, but none work. With enough messing around I can
get some parts fontified, but it's not consistent. Yes, I have setq-
default font-lock-multiline to true.
Anyone gotten multiline fontification in any mode to work? How?

You will need to use a function which searches for a range
larger than the range which font-lock usually searches for,
instead of a regexp. I tried it in the *scratch* buffer using
the following configuration:
(defun find-brackets (limit)
(or (re-search-forward "<%[^>]*%>" nil t)
(let ((start (point)))
(if (and (search-backward "<%" nil t)
(search-forward "%>" nil t))
(goto-char limit)
(goto-char start)
nil))))
(setq font-lock-keywords (append font-lock-keywords
'((find-brackets (0 'underline t))))
font-lock-multiline t)

font-lock-multiline is probably not the right tool here (it works OK for
things that are "generally single line, but something spread over a couple
more lines", but for really long sections forget it).
Your best bet is to mark <% and %> as string (or comment) delimiters in
font-lock-syntactic-keywords. If you want to highlight them in a different
face that the string-face or comment-face, then use
font-lock-syntactic-face-function.

KA-BANG!!!!!!!!!!!!!!
I'm trying it in the beta version of the next version wannabe of
html-helper-mode - masochist can find it at the following url:
<http://savannah.nongnu.org/download/baol-hth/beta-html-helper-mode.el.gz>
but it falls one tag short (it seems it fails to decorate the last tag
- an html tag could span multiple lines)
Where can I learn how to write it properly ?
The tex-mode example was a too little help for my limited skills (and
intellect).
TIA!!!!

I don't have time to read your code and guess the problem.
Please post more specific/detailed questions.

I read the Syntax Tables section of the Elisp info manual and
found how do I highlight text between <% and %>. That the
simplest way to do that in the *scracth* buffer will be the
following:
(setq font-lock-syntactic-keywords '(("\\(<\\)%" 1 "< b")
("%\\(>\\)" 1 "> b")))
I will look for the way to highlight <%foo%> and <%bar%> by
different face. Thank you.
