How to download/install pdf2text or catdoc libraries

Libraries pdf2text and catdoc should be free, so you don't have to pay for it.

PDF2TEXT (PDFTOTEXT) SHOULD BE FREE:

Debian, Ubuntu:
sudo apt-get install xpdf
Centos, RedHat:
sudo yum install xpdf

Update: If the package xpdf is not available use pdftotext from poppler-utils
sudo apt-get install poppler-utils
sudo yum install poppler-utils

Windows:
www.foolabs.com/xpdf/download.html

CATDOC (CATDOC, CATPPT, XLS2CSV):

Debian, Ubuntu:
sudo apt-get install catdoc
Centos, RedHat:
sudo yum install catdoc
Windows:
blog.brush.co.nz/2009/09/catdoc-windows/

On Windows you have to set manually CLASSPATHS to bin folders of those libraries. Catdoc has also catppt and xsl2csv. Do not forget to add them to CLASSPATHS too.
