Watermark v 1_3_2 (www.accesspdf.com watermark_pdf.java)

When trying to create watermark I receive the following message:

You need pdftk for this script.
Please go to http://www.accesspdf.com and download it.

When i go to the site to download wathermark_pdf.java it does'nt say what i need to do with the file.
