scrape data from pdf files

Attached are 3 sample PDF files. I want to know if it's possible to scrape the data from the files and store the data as texts in a mysql database. So what i want is a program i can run myself and possibly adapt over time. I need to differentiate between the dutch and french pieces of text, i also need to differentiate between sections and titles and actual text so i can use the titles to scrape what i need and skip the rest. Please indicate how accurate this scraping can be, what % accuracy can a program achieve and what % will need to be checked manually. I'd prefer a program in Java but i'll also consider PHP, no other languages. I am familiar with these languages myself as well as mysql but not with the pdf format.
