I don't have any major-mode for "*.jou" files; if you don't have
either, the following should work for you.
(add-hook 'find-file-hooks
(lambda ()
(when (string-match "\\.jou$" (buffer-file-name))
)
(font-lock-add-keywords nil
'("\\(/.*\\)$"
(1
font-lock-comment-face)))
(font-lock-mode)
)
)
So, in short:
1) Your line with `font-lock-add-keywords' must be evaluated in the
right buffer.
2) And you have to turn `font-lock-mode' on in the buffer for
fontification to happen.
If you want to add more features, you should probably take the time to
define your own major mode "jou-mode":
(info "(emacs)Major modes")
(info "(elisp)Major modes")
PS: I don't know what "jou" files are, but, if you are writing your
own journal file, you should give `org-mode' a try; it's a
wonderful addictive tool to take notes, to make plan and publish
everything in LaTeX, HTML, etc.
And it is included in recent versions of GNU Emacs.
