Hi
all,
I am
trying to properly use paths to images, links and what not within my "outside"
web application. I will also have the inside and admin applications deployed in
the same one web container (Orion App Server). Originally, I would ALWAYS do the
following for links and images:
<img src="/images/image.gif">
<a
href="/path/page.jsp">click</a>
<a
href="<%= contextPath
%>/path/page.jsp">Click</a>
where
<%= contextPath %> is set to: request.getServletPath().substring(0,
request.getServletPath().lastIndexOf("/"));
A few
problems are occuring. First, when deploying one web-app to the "root" /, and
another to /inside, and the last to /admin, in the /inside or /admin web-apps,
when I refer to <img src="/images"> it appears to look in the ROOT web
application, images folder. Obviously, this won't work..unless ofcourse the
right image is in the root application. But I don't want one web-app to rely on
another deployed apps paths for any resources..all must be relative to its own
web-app so it can be deployed as a stand-alone app. I would guess this is not
all that uncommon of a way to deploy (and develop) web-apps?
So
now, my thinking was since each web-app runs in its own context, and I have 3
(/, /inside and /admin), that using the <%= contextPath %> in every link
and img, would work. However, as I have found out, when a page exists in say
/prdoucts/index.jsp, the <%= contextPath %> returns http://localhost/products so that ALL
my links are now starting off from that location. What I really want to do is
have some sort of variable in EVERY link and img that references the WEB-APP
root location, and not the current path a page is in. Is there a way to get the
specific web-application root from a page running within that web-app? Also, is
it required to use <img src="./images/image.gif"> when referring to the
images dir from the ROOT dir of any given web-app? If I use the /images, as i
said above, it alwyas navigates to the / context web-app, unless the current
web-app is the only one running.
I
guess what I am really looking for is the proper way to handle paths to
resources from within JSP pages (and servlets) that stick to the web-app its
running in, yet somehow using a common way to do this to guarantee all links and
resources follow this same path.
Thanks.
