Thanks, I have got it working now. I couldn't get a Configurable
component to work for some reason, so I ended up with a Parametizable
one which is just as good for my purposes because there's only one
instance of it in the sitemap. I pass in a default image url prefixed
with context:// and I look it up inside the reader with SourceResolver
when I need it. It seems to work fine.
How would I have made it work as a Configurable reader? I had this in
my sitemap:
<map:read type="conceptimage" mime-type="image/gif" src="{1}"/>
<map:parameter name="defaultFilename"
value="context://images/default.gif"/>
</map:read>
but from the reader's configure() method,
config.getAttribute("defaultFilename") just threw an exception.
Thanks also Ard for your suggestions.
Jon
