I've been working with Apache FOP for converting XML (held on a BaseX instance) to PDF. Currently this involves saving nodes from the BaseX database to pass into a local FopFactory - not ideal. Have tried to pull one of the documents out and get a 500 error, then tried referencing direct files - which also errors:
import module namespace fop = 'org.basex.modules.fop.FOP'; let $xml := db:open('billing_run_435')/CommercialDocument[@id="203545"] - if returned does show xml let $xsl := xslt:transform('/home/chris/Downloads/xml/billing_invoice_241040.xml', '/etc/xmlmapper/pdf_invoice.fo') - hard coded for debugging return $xml
From the log:

Both '/home/chris/Downloads/xml/billing_invoice_241040.xml' and '/etc/xmlmapper/pdf_invoice.fo' exist as I use them in a local java fopfactory which processes them fine.
