Highlight text in pdf file

Question

Has anyone worked on "Regenerate the PDF appearance stream and draw a box behind the text highlighted.
3rd point of this link - http://incubator.apache.org/pdfbox/userguide/highlighting.html.
I have one pdf file and I know the X, Y cordinated and height and width of text to highlight.
I am using pdfbox utility.and i want to highlight the existing text with yellow color.
Any help would be highly appreciated.
Thanks
