Hello,
The built in filter for PDF's (PDFbox) has a few limitations, such that it
can't filter every PDF, but it is easy to ship with DSpace such that a basic
installation is easy as possible.
You're in luck, because with an extra step, you can install XPDF, which is a
plugin for filtering PDF's that is much better than the default, and has
helped us to filter more PDF's.
You can read more about it here, and learn how to install it. Its not
difficult to configure once you've installed xpdf on your system.
1.5 http://www.dspace.org/1_5_2Documentation/ch05.html#N12768
<http://www.dspace.org/1_5_2Documentation/ch05.html#N12768>1.6
http://www.dspace.org/1_6_2Documentation/ch05.html#N14F32
1.7

You could also try to update your pom.xml to fetch a more current version of
PDFbox, but no guarantees. There are some improvements to the pdfbox filter
in DSpace 1.7.
