Thanks.
>From an implementation point of view there is much use of
string-join(('"', json:escape($name), '":',
json:print-value($x)), "")
Vs. what I'd naturally do
concat('"', json:escape($name), '":', json:print-value($x))
Is this a stylistic issue ? or is there a performance or other reason to prefer
string-join ?

FYI, as a MLJAM user you don't have to do any Java coding to use FOP. The
jam-utils.xqy has a function that does it for you.
(:~
: Returns a PDF generated from the given XSL-FO element using the Apache
: FOP 0.92 engine.
:
: Depends on jam:start() having previously been called.
:
: @param $xslfo The XSL-FO element to render as PDF
: @return A binary() node holding the generated PDF document
:)
define function jamu:fop(
$xslfo as element()
)
as binary()
If people write other useful functions like that, send them my way and I'll
incorporate them into the utils package.
Which reminds me, on my todo list, but someone else could easily beat me to it,
is optimizing MLJAM to use MarkLogic Server's somewhat recent functionality to
send and accept a raw binary POST body -- which should be a performance
optimization compared to encoding/decoding the binary as a string as MLJAM does
today.

Along the lines of the other comments ...
What I use in production is a local tomcat server running the xmlsh servlet.
http://www.xmlsh.org/EmbeddingServlet
Then from MarkLogic I package all the files needed for a PDF (including the
source XML, as well as all images) into a ZIP stream, base64 encode it and
POST it to an xmlsh servlet.
The servlet then unencodes, unzips the files, uses XSLT to produce FOP then
Apache FOP to produce a PDF.
It then sends back the PDF to MarkLogic which then pushes it out to the client
with the right Content-Type for PDF.
This allows dynamic generation of PDF from a ML hosted application, entirely
scripting based (only a few lines scripting of code on both ends).
This is architecturally similar to the MLJAM solution but doesn't require any
java coding.

Subject: [MarkLogic Dev General] output PDF from MarkLogic?
Is there a library for outputting PDF files from MarkLogic? I found plenty of
information about converting PDF to XML, but what about the other way around?
Thanks,
Ryan
