[JDEE + MMM-Mode + JSP] Teach JDE about JSP-style imports

[Kai Grossjohann]

Say I have the following *.jsp:

<%@ page import = "java.net.URI" %>
<%
URL foo = new URL("http://www.gnu.org/";);
%>

Now this won't work because I'm importing URI and not URL.
Further, even if it was URI, I couldn't hit C-c C-v C-g on it because
JDE mode doesn't know about the import of java.net.URI.

How to teach JDEE about these weird import statements?

My config uses mmm-mode to edit *.jsp files, as follows:

(require 'mmm-mode)
(require 'mmm-sample)
(add-to-list 'auto-mode-alist '("\\.jsp\\'" . html-mode))
(setq mmm-global-mode 'maybe)
(mmm-add-group 'jsp
               '((jsp-code
                  :submode jde-mode
                  :match-face (("<%!" . mmm-declaration-submode-face)
                               ("<%=" . mmm-output-submode-face)
                               ("<%"  . mmm-code-submode-face))
                  :front "<%[!=]?"
                  :back "%>"
                  :insert ((?% jsp-code nil @ "<%" @ " " _ " " @ "%>"
@)
                           (?! jsp-declaration nil @ "<%!" @ " " _ " "
@ "%>" @)
                           (?= jsp-expression nil @ "<%=" @ " " _ " "
@ "%>" @))
                  )
                 (jsp-directive
                  :submode text-mode
                  :face mmm-special-submode-face
                  :front "<%@"
                  :back "%>"
                  :insert ((?@ jsp-directive nil @ "<%@" @ " " _ " " @
"%>" @))
                  )))
(add-to-list 'mmm-mode-ext-classes-alist '(nil "\\.jsp\\'" jsp-code))
