How to use a relative URI in the config file (in 'renderer/fonts/font/@embed-url')
Hi
I have a little trouble to use a relative URI in the FOP config file.
Here is an excerpt:
<renderer mime="application/pdf">
<fonts>
<font metrics-url="../fonts/arial.xml"
embed-url="../fonts/arial.ttf">
<font-triplet name="Arial"
style="normal"
weight="normal"/>
</font>
</fonts>
</renderer>
I got the following:
pdf.Failed to embed fontfile: ../fonts/arial.ttf(URI could not be
resolved (no protocol: ../fonts/arial.ttf): ../fonts/arial.ttf)
I tried to use "file://../", "file://.././", etc., but no one works.
The only one that works is an absolute one, but I really can't use
this.
Any idea? PS: I use FOP-0.91.
Regards,
--drkm

Well, as I remember from my read of the related RFC, the trailing
double slash in the protocol in a URL string is not optional, so the
above URL is 'erroneous'. What the resolver probably could do in this
case is much like what any decent browser does when you type
'http:www.some-site.net', and append the double slash to the protocol
string, so the URL would eventually become your intended result
> file://../../../config/ru/
It seems like it depends on how you extract the protocol string from
a given URL. Do you wait for the two slashes, or stop at the first
colon and then check whether two slashes immediately follow and
insert them if necessary?
Cheers,
Andreas

I haven't tried 0.91 yet, but in 0.20.5 the above URLs did work as
relative (although indeed they shouldn't). Worse: if you left out the
//, they didn't work anymore. I have fontBaseDirs for several
languages that look like this (relative to baseDir):
../../../config/ru
But if I put it like that in userconfig.xml, FOP complains about the
missing protocol. This shouldn't be an issue, but OK, I change it to:
file:../../../config/ru
Now the resolver seems to eat the first four dots (waiting until it
encounters two slashes?) and looks in ../config/ru, which doesn't
exist. To make FOP find the dir, I can specify this:
file:../../../../config/ru (notice the *extra* ../)
or even this:
file:./../../../config/ru
or this:
file://../../../config/ru
There's also something wrong at the other end: if the location isn't
found, the "/ru" part will be left out of the "not found" message. If
I put a slash at the end, this doesn't happen.
So, to wrap it all up, in order to have FOP look for my metrics files
in ../../../config/ru *and* give me the right error message if it
doesn't find them, I have to specify the fontBaseDir as:
file://../../../config/ru/
BTW, there seems to be a similar (though not exactly equal) problem
in Ant.
All that said, let me also make clear that I love FOP and that I
HUGELY appreciate the efforts of all you people who brought it to us
and are working hard to improve it. Without Apache FOP, the Firebird
open source project would have no PDF documentation, or at least we
would be dependent on individuals who had the money to buy a
proprietary FO processor and the time and kindness to build our docs.
Now every project member can build great-looking PDFs, using only
open-source tools. Thanks!
Greetings,
Paul Vinkenoog

Have enough of these complaints and fixed it (I hope so at least).

Ok, thanks for pointing this out. I'll look for an other way to
achieve my goal (I unfortunately don't know FOP enough to try to
contribute here).

FOP 0.91 currently can't deal with relative URLs for embedding. Neat
comment in the relevant code:
/**@todo Temporary hack to compile, improve later */
return new java.net.URL(uri).openStream();
Don't expect a quick fix,Getting the necessary information for
resolving relative URLs at this point will need some work.

Neither of these two is an relative URL, as you might have thought.
