RE: Location of external graphics
This may not be the appropriate forum (may be more of a Java question), so I
asked for your forbearance.
We are struggling with where to keep our image files. Right now we loading
them with absolute file paths. This works for one application that "builds"
the path based on environment information. This allows us to maintain
portability.
We have another application that does not know anything about its
environment. When the application is moved from a development server to a
production, we must update the stylesheet to reflect the server change. We
would like to avoid this.
It appears that file references, if not absolute, are relative to the (and
here's the part we are a little fuzzy on) the classpath for our FOP servlet?
If this is the case, I guess we can put them in the WAR file and then
redistribute it as needed. I was hoping for a cleaner solution.
Thanks,
Pete Allison

Bundling the stylesheets in the WAR file is one solution that many users
seem to be using. Another could be using a XML Catalog (using XML
Commons Resolver from the Apache XML project). More information on the
resolver here:
http://xml.apache.org/commons/components/resolver/index.html
http://wiki.apache.org/xmlgraphics-fop/HowTo/XmlCommonsResolver
With an XML Catalog you could do things like rewriting URIs like:
myresources:xslt/mystylesheet.xslt
to:
file:/home/user/resources/xslt/mystylesheet.xslt
The XML Commons Resolver implements both the EntityResolver and
URIResolver interfaces. In FOP, you can configure your own URIResolver.
However, the Java example on the Wiki page above (as I had to notice now)
is hopelessly outdated. I'll see to it that it is updated.
Yet another way is to just set the base URI on the FopFactory to
something you define. But then you're still using relative filenames.
Not that this is bad in any way. But it can be hard to debug.
