Hmmm
I think you are talking about how we do it
We process contents of web pages from the web pulling in data etc from
remote sites and putting them into a template,
A small example here (imagedataservlet returns xml containing the width and
height in pixels of an image)
<xsl:template name="crop-scale-image">
<xsl:param name="content-width"/>
<xsl:param name="content-height"/>
<xsl:param name="imgurl"/>
<xsl:variable name="imginfourl">
<xsl:text>http://www.example.com/ImageDataServlet-1.0/ImageDataServlet?imgsr
c=</xsl:text>
<xsl:value-of select="$imgurl"/>
</xsl:variable>
<xsl:variable name="imginfo"
select="document($imginfourl)"/>
<xsl:variable name="imgWidthmm"
select="$imginfo/imginfo/imgwidth div 3.779527559"/>
<xsl:variable name="imgHeightmm"
select="$imginfo/imginfo/imgheight div 3.779527559"/>
<xsl:variable name="xscale" select="$content-width div
$imgWidthmm"/>
<xsl:variable name="yscale" select="$content-height div
$imgHeightmm"/>
<xsl:variable name="scale">
<xsl:choose>
<xsl:when test="$xscale >= $yscale">
<xsl:value-of select="$xscale"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$yscale"/>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:choose>
<xsl:when test="$yscale > $xscale">
<fo:external-graphic
scaling-method="resample-any-method"
height="{$content-height}mm"
width="{$content-width}mm"
src="{$imgurl}"
content-x="0mm"
content-y="0mm"
content-width="{$imgWidthmm
* $scale}mm"
content-height="{$imgHeightmm * $scale}mm"
clip="auto"
movie="auto"
/>
</xsl:when>
<xsl:otherwise >
<fo:external-graphic
scaling-method="resample-any-method"
height="{$content-height}mm"
width="{$content-width}mm"
src="{$imgurl}"
content-x="0mm"
content-y="0mm"
content-width="{$imgWidthmm
* $scale}mm"
content-height="{$imgHeightmm * $scale}mm"
clip="auto"
movie="auto"
/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>

Subject: problem resolve external image resource with fop
hi,
i have a problem using a fop in a web application. First of all, this is
not only only a kind a web application but a maven web application with
others dependencies like libs or maven module (not web) linked. One kind of
this lib/maven module keep the source with embed a fop code for translate
xml into pdf using an xsl stylesheet. My problem is that the user request is
processed by a servlet. I try to use URIResolver with ServletContext and
"servlet-context:" for accessing external resource in xsl with
"<fo:external-graphic src="servlet-context:path
webapp/images/nameGifImage.gif">". This is work fine but i prefere that fop
access resource without serveletContext but with the ClassLoader without
placing images in a context web root. I try to place my images in a
application class-path where fop is embed but this not work. Anybody now how
can i solve my problem? How can find where fop external resource would be
place?
Thank you very much
Roby
