how can do that by java

thank in advance

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.

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.
