With the correction you made above, I get the same result as you -
it works!
Thanks so far, I will now continue with the next step. I'm certain
I will be back with more questions soon:-)
So here it comes:-)
I got the simple version to work, now I would like to extract some
info based on the requested document. I thus changed the pelt.fv hook
to this:
<forrest:hook class="languages">
<forrest:contract name="language-variants"
dataURI="cocoon://#{$getRequest}.languages.xml"/>
</forrest:hook>
Notice the @dataURI I've added.
I *think* I understand what's going on - here's what I believe,
please verify or correct any misconception:
- the dataURI is looked up separately, and the returned data is
served as an argument (XML snippet) to the contract, to do whatever
more is needed
I have found matches for cocoon://**.title.xml, and copied it to my
local sitemap, and modified it:
In src/documentation/sitemap.xmap:
<map:pipeline>
<map:match pattern="**.languages.xml">
<map:generate src="cocoon://{1}.xml" />
<map:transform src="{lm:dataModel-xml-document-to-
languages.xsl}" />
<map:serialize />
</map:match>
</map:pipeline>
This should give me the source document, which is transformed with
the specified stylesheet. I have the following in:
src/documentation/resources/stylesheets/xslt/xml/document-to-
languages.xsl
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/
Transform">
<!-- Template to generate the document language -->
<xsl:template match="document">
<xsl:choose>
<xsl:when test="@xml:lang">
<xsl:copy-of select="@xml:lang"/>
</xsl:when>
<xsl:otherwise>
<title>*No* language found</title>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
which I think the locationmap should be able to resolv, based on the
following snippet in plugins/o.a.f.plugin.internal.dispatcher/
locationmap.xml:
<match pattern="dataModel-xml-document-to-**.xsl">
<select type="exists">
<location
src="{properties:resources}stylesheets/xslt/xml/
document-to-{1}.xsl"
/>
<location
src="{lm:std-dataModel-xml-document-to-{1}.xsl}"
/>
</select>
</match>
With all this, and without changing the contract from what was
working earlier, I get the following error:
Internal Server Error
Message: null
Description: No details available.
Sender: org.apache.cocoon.servlet.CocoonServlet

cause
dispatcherError: 500 - Internal server error
The contract "language-variants" has thrown thrown an exception by
resolving raw data from "cocoon://index.languages.xml".
dispatcherErrorStack:
org.apache.excalibur.source.SourceException: Cannot get input
stream for cocoon://index.languages.xml
request-uri

From what I can see, it isn't able to resolve the stylesheet OR the
source document for some reason.
