It Works!! Thank you Geert.
I attach an example performing a digital signature over a PDF using iText.
Your sitemap.xmap must have the new serializer defined:
<map:serializer logger="sitemap.serializer.fo2spdf"
mime-type="application/pdf"
name="fo2spdf" src="
org.apache.cocoon.serialization.PDFSignSerializer"/>
And you need a new "match" using this serializer:
<map:match pattern="kk">
<map:generate src="samples/hello-world/content/hello.xml" />
<map:transform src="samples/hello-world/style/xsl/page2fo.xsl"
/>
<map:serialize type="fo2spdf" />
</map:match>
Hope it helps :)
