[MarkLogic Dev General] Error in saving a converted PDF file

[Michael Blakeley]

Vikas,

It sounds like you're trying to rebuild functionality that already 
exists in the Content Processing Framework (CPF). Why don't you simply 
set up CPF (per the docs), then call xdmp:document-load() with the path 
to your PDF?

If you set up CPF correctly, a set of triggers will do the PDF 
conversion for you.

-- Mike

PS - your problem is that cvt:save-converted-document takes a source 
URI, per 
http://developer.marklogic.com/pubs/3.1/apidocs/Convert.html#save-converted-documents 
- but you are giving it a filesystem path. Again, use CPF.
