Answer 1

PDF files are PostScript, which is very difficult to process. I doubt there's an easy way.

Take a look at http://java-source.net/open-source/pdf-libraries , but be aware you might have some difficulty.

Also, read http://partners.adobe.com/public/developer/en/pdf/HighlightFileFormat.pdf for the specs of the highlight format. Depending on what "place" information you need, that might be enough.

Answer 2

How are you displaying the PDF? If you are displaying the image, you just need the word co-ordinates. Something like PdfBox or JPedal or maybe IText can do this.
