iText5.1.0 set header and footer in document [clos

i m using servlet to view pdf file as using response setContentType pdf.

I want to set Header and Footer of Document generated by IText 5.1.0.

Please Help..

Forget about the servlets for a second. Make sure you can get the header/footer to work locally.

Edit: I was a bad SO user by posting about outdated HeaderFooter stuff. It seems a lot of people are doing this, making it extremely hard to find succinct examples of this question. add header to pdf using iText answers this question.

Here seems to be the correct way to do it: (Modified from http://itextpdf.com/examples/iia.php?id=104 ): https://gist.github.com/977502
