simple JSP redirect to another page -- how to deal with relative URLs
I previously asked about remapping URLs and got some helpful
responses. In a nutshell, this was recommended:
http://tuckey.org/urlrewrite/
Looks very good for some purposes.
But I also want to solve a much simpler problem--
I have a very large amount of static content (articles), with each
article in its own directory. A main Table of Contents links to the
start page in each directory, which is *not* index.html (eg some-main-
page.html). I don't want to rename or change those pages as they have
world-wide direct links to them--they have to stay as-is. But I do
want to insert an index.jsp page without altering any content.
For many of these folders inserting a trival index.jsp solves the
index-page problem:
<%@ include file="the-main-page.html" %>
(though I do wonder if google consider this unacceptable duplicate
content)
My pages all use relative links eg "..", "./", etc. So this works
***when the page being included is in the same directory**.
But when the include page is in another directory, none of the
relative links work. None of these variants do the right thing; any
referenced images cannot be found.
<%@ include file="../ReviewInfo.html" %>
<jsp:include file="../ReviewInfo.html" %>
<jsp:forward page="../some-other-page.html" />
The jsp:forward directive seems perfect, but the flaw of not changing
the current location (eg no "cd" is done first) makes it useless for
this purpose. Or does it? Is there something I'm missing here?
Alternately, is there some other trivial solution?
URL-rewriting is not appropriate in this case; there is no particular
pattern, just a fair number of specific cases. I was hoping for a
simple 1-line index.jsp in each directory.

Right, it's work to fix them -- but you're spending time and effort now
to find a way to work around a standard JSP behavior. Fix 'em once,
do it the right way from now on, you're golden :-)

Not sure what that means, but...
FWIW!

Hassan,
As I said there are other issues. Making them fixed paths would mean
I couldn't edit them, copy them (for revisions, etc) without having to
fix up numerous pages. And the uses are not only when routed through
a web server.

I've never -- and that's a long time, web-wise :-) -- liked relative paths
for this reason, among others.
If I were you I'd bite the bullet and fix 'em once and for all.

David,
Yes, I understand how relative paths work.
The problem is that the jsp include directives:
- include an html page that is *not* in the same directory as the jsp
page;
- the relative links in the included html file are supposed to be
relative to their own directory not the directory of the JSP.
eg:
/foo/bar/index.jsp
/foo/some-page.html
index.jsp contains
<jsp:forward page="../some-page.html" />
This doesn't work; a link "images/foo.jpg" in some-page.html ends up
being /foo/bar/images/foo.jpg instead of /foo/images/foo.jpg.

Your examples may be simplified from the real thing, but remember what
the .'s mean: a single one means the current folder, and a double means
the parent of the current folder. So get into another directory at the
same level (both subfolders of the same parent folder), you need to go
up with the double dot, and then back down into the other folder. For
example, if you are in folder B, which is a subfolder of A, and you want
to get into C, which is also a subfolder of A, you need to do:
../C/myotherpage.html.

If I were given this problem, I'd probably write a Filter that uses a
properties files to resolve references. Something like:
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain)
throws IOException, ServletException {
if(request instanceof HttpServletRequest && response instanceof
HttpServletResponse) {
HttpServletRequest hrequest = (HttpServletRequest)request;
HttpServletResponse hresponse = (HttpServletResponse)response;
String req = hrequest.getServletPath();
if(req.length() > 0)
req = req.substring(1).replace('/','.');
String where = map.get(req);
if(where != null) {
hresponse.sendRedirect(where);
return;
}
}
chain.doFilter(request, response);
}

Christopher,
Well, I'm not a web expert, so if there's a better way (redirect) I'm
all ears.
From what I can find by googling, redirects have a slew of issues of
their own. But I'm a newbie at this, so I might be misunderstanding.
How would I do a redirect in Tomcat for my stated issue, keeping in
mind that doing so is case-by-case, not a nice regexp pattern.

This is a very weird way to do things. You should either generate
content /or/ forward. Why are you doing both?
Instead of using a forward, why not do a redirect? That way, the new
request has the correct URL and your relative paths should be correct.

Thanks, I've tried that. Including with a full path still makes the
included file relative to the directory in which the jsp resides.

Posted by DIGLLOYD INC <di...@diglloyd.com>.
Thanks for everyone's help on this and my related message.
I found that using org.tuckey.web.filters.urlrewrite.UrlRewriteFilter
works well: http://tuckey.org/urlrewrite/
With entries like:
<rule>
<from>/diglloyd/free/CardReaders/CardReaders.html</from>
<to type="redirect">/diglloyd/free/CardReaders/</to>
</rule>
(I'm not sure if I should stick "index.html" in the "to" URL)

Re: simple JSP redirect to another page -- how to deal with relative URLs
Posted by DIGLLOYD INC <di...@diglloyd.com>.
David,
I want to redirect perhaps a dozen links in directories that have a
main page accessed something like:
/stuff/start-page.html
In thinking about this, maybe my best solution is to rename the main
page to "index.html" for simplicity and use the org.tuckey.web.filters.urlrewrite.UrlRewriteFilter
with basic patterns.

Seconded.

The only trouble I've had with redirects is when you redirect to a
page which redirects to a page which redirects to a page. Browsers
consider more than a few redirects in a row to be a bad thing and they
stop. My experience taught me (about 7 years ago) that more then 2 was
pushing things.
DIGLLOYD are only replacing a single generation of files, as you do
this "relinking" how many links do you want to "forward" or "redirect"?

Dave

Never mind .. I saw your other responses and the best solution is the
redirect option. After following the redirect, the browser will have
the correct URL for calculating the full url of each of the page's
resources.

Re: simple JSP redirect to another page -- how to deal with relative
URLs
Posted by David Smith <dn...@cornell.edu>.
I see the problem. You could use absolute paths in jsp includes and the
servlet container would understand them as relative to the webapp's root
as opposed to the server's root:
Say you have this file layout
webapp
| index.jsp
| article1
| index.jsp
| article1.html
| article2
| index.jsp
| article1.html
article2/index.jsp could simply have <jsp:include
file="/article1/article1.html" /> and it would find article1.html in the
article1 folder.
