Generating header/footer with flying saucer (xHTMLRenderer) and iText

I realize this question has been asked before (I looked at all the solutions and tried them all) but I am still trying to generate a pdf document with a header and footer that repeat on every page.

I am using flying saucer R8 with iText2.0.8 I have tried many different methods to get it working but so far to no avail. Some methods I tested out were https://gist.github.com/626264, using running elements and margin boxs http://pigeonholdings.com/projects/flyingsaucer/R8/doc/guide/users-guide-R8.html#xil_40 (css3 feature), a guide for flying saucer r7 that doesn't work for r8 http://today.java.net/pub/a/today/2007/06/26/generating-pdfs-with-flying-saucer-and-itext.html#page-specific-features, a long with many other methods which did not work for me.

My header div contains 2 other divs with images and my footer is just for page numbering. The html is being put into a StringBuffer called buf.

buf.append("<head>");     buf.append("<title>blabla</title> ");     buf.append("<style type='text/css' media='print'>  ");     buf.append("@page { size:8.5in 11in; padding:1em; @bottom-left { content: element(footer); } } ");     buf.append("#footer { font-size: 90%; font-style: italic;  position: running(footer); top: 0; left: 0; }");     buf.append("#pagenumber:before { content: counter(page); } ");     buf.append("#pagecount:before { content: counter(pages); } "); buf.append("</style></head>"); buf.append("<body>");  buf.append("<div class='header' style='clear:both;'>");     buf.append("<div id='moneyLogo' style='float:left'>");      buf.append("<img src='logo.jpg' alt='Some alt text' />");     buf.append("</div>");     buf.append("<div id='canLogo' style='float:right'>");     buf.append("<img src='someImg.gif' alt='alt text' />");     buf.append("</div>");     buf.append("<h3 style='text-align:center; clear:both;'>alt text</h3>");     buf.append("<div style='text-align:center;'>");     buf.append("Some texy text");     buf.append("<br />"););     buf.append("</div>");     buf.append("</div><br /><br />"); buf.append("<div id='footer'>  Page <span id='pagenumber'/> of <span id='pagecount'/> </div>");      buf.append("</body>");     buf.append("</html>"); 

My pdf generates fine except for the fact that the header only appears on the first page and the footer only appears on the bottom of the last page. When I put the html through the w3c validator it came out fine, but when I used their CSS validator it said that their were parse errors in the line @page { size:8.5in 11in; padding:1em; @bottom-left { content: element(footer); } }

As far as I could tell from all the guides I was reading this was fine. I also heard that the W3C CSS validator was incomplete for CSS3 specs so I assumed it was the validator who was wrong.

If anyone could give me some tips of where to look or ideas it would make my week :)

p.s. Has to use Flying saucer R8 and/or iText 2.0.8

Here is a working example:

package com.sg2net.test;  import java.io.FileNotFoundException; import java.io.FileOutputStream;  import org.xhtmlrenderer.pdf.ITextRenderer;  import com.lowagie.text.DocumentException;  public class XHTMLRenderer8 {      /**      * @author Giovanni Cuccu      */     public static void main(String[] args) throws FileNotFoundException, DocumentException {         ITextRenderer renderer = new ITextRenderer();         String content="<html><head><style>\n" +           "div.header {\n" +           "display: block; text-align: center;\n" +            "position: running(header);}\n" +           "div.footer {\n" +           "display: block; text-align: center;\n" +            "position: running(footer);}\n" +           "div.content {page-break-after: always;}" +           "@page { @top-center { content: element(header) }}\n " +           "@page { @bottom-center { content: element(footer) }}\n" +           "</style></head>\n" +           "<body><div class='header'>Header</div><div class='footer'>Footer</div><div class='content'>Page1</div><div>Page2</div></body></html>";         renderer.setDocumentFromString(content);         renderer.layout();         renderer.createPDF(new FileOutputStream("test.pdf"));      }  } 

This is using the following XHTML document

<html> <head> <style> div.header {     display: block; text-align: center;      position: running(header); } div.footer {     display: block; text-align: center;     position: running(footer); } div.content {page-break-after: always;} @page {      @top-center { content: element(header) } } @page {      @bottom-center { content: element(footer) } } </style> </head> <body>     <div class='header'>Header</div>     <div class='footer'>Footer</div>     <div class='content'>Page1</div>     <div>Page2</div> </body> </html>
