I've asked around for alternatives for PDF scraping, and got a tip about <URL: http://tabula.technology/ > (still being developed), <URL: https://github.com/okfn/pdftables > (no longer developed) and finally <URL: http://pdftables.com > which is the commercial successor of the discontinued github project.
Might be a better alternative, as pdftable seem to no longer be maintained either. Tabula written in Java seem to be the only maintained free software project for scraping tables out of PDFs. -- Happy hacking Petter Reinholdtsen
