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

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>

Hi,
Can you please provide steps to create a new servlet and at what place we
should use "FopFactory.setURIResolver(URIResolver). " in
ApacheFOPWorker.java

Roby,
then don't use the ServletContextURIResolver and instead write your own
URIResolver which then can work exactly how you want it. You could
define your own "classpath:" URI scheme. You could copy FOP's
ServletContextURIResolver and adjust it to your liking. Then just set
your new URIResolver instead of the ServletContextURIResolver using
FopFactory.setURIResolver(URIResolver). That allows FOP to find your
images the way you want FOP to. HTH
