Re: PDF: external-graphic & absolute pat
Hello,
content-width and -height are not supported for FOP 0.20.5, as seen on this
page
http://xmlgraphics.apache.org/fop/compliance.html#fo-property-content-width
and yes, width / height are the way to go...but not both at the same time
since that would destroy the aspect ratio of your images, if I recall
correctly.

Wrong place. The baseUrl is to be passed into the XSL transformation, the
reader that's returning the bitmap doesn't need to know it. And besides,
even if you had a reader that e.g. embedded the URL in an EXIF field in the
JPEG, you'd have to put the parameter inside the <map:read> element rather
than inside the <map:match>. You'd only need it there if the wildcard URI
matcher were written to expect a parameter of that name.

You need to use
<map:transform src="xsl/xml2html.xsl">
<map:parameter name="baseUrl"
value="http://{request:serverName}:{request:serverPort}{request:contextPath}"/>
</map:transform>
and the transformer will then pass the parameter to the XSL transformation
engine, which will allow you to access it within xml2html.xsl using a
top-level (at the start, outside any xsl:template) <xsl:param
name="baseUrl"/> element. Then, when you output the external-graphic
elements, use <fo:external-graphic src="{$baseUrl}/whatever.jpg"/>

The container shouldn't matter, I've used this technique running in Tomcat
on my own machine, then deployed the same war to Websphere. It worked the
same in both.

I tried to do this into my sitemap.xmap
<map:match pattern="*.jpg">
<map:parameter name="baseUrl"
value="http://{request:serverName}:{request:serverPort}{request:contextPath}"/>
<map:read mime-type="image/jpg" src="img/{1}.jpg"/>
</map:match>
and I tried to put it also here:
<map:match pattern="*.html">
<map:generate src="xml/{1}.xml"/>
<map:transform src="xsl/xml2html.xsl"/>
<map:serialize type="html"/>
</map:match>
but seems that baseUrl is a blank string... so it doesn't work for me...
could you suggest me why?
IT could depends by the fact that I'm actually running cocoon in Tomcat?
