Itext pageNumber Display in PDF

Question

Hi guys i have a java class which is used to show header and footer in iText PDF.

the page number is showing in top of the page and footer is coming correctly in footer section.. now i want to display the page number in footer place...

following code im using

public HeaderAndFooter() {

header = new Phrase("**** Header ****");

footer = new PdfPTable(1);

footer.setTotalWidth(130);

footer.getDefaultCell().setHorizontalAlignment(Element.ALIGN_CENTER);

footer.addCell(new Phrase(new Chunk(

"**** Footer summary****")

.setAction(new PdfAction(PdfAction.FIRSTPAGE))));

}

public void onEndPage(PdfWriter writer, Document document) {

PdfContentByte cb = writer.getDirectContent();

ColumnText.showTextAligned(cb, Element.ALIGN_RIGHT, new Phrase(String.format("%d", writer.getPageNumber()),

PDFUtil.getNormalFont()), (document

.right() - document.left())

/ 2 + document.leftMargin(), document.top() + 10, 0);

footer.writeSelectedRows(0, -1,

(document.right() - document.left() - 300) / 2

+ document.leftMargin(), document.bottom() - 10, cb);

}


}

im getting output like this

                                        1 (header)

26-Aug-2011 Rentaldetails August ---- 5500 month

                            ****

kindly suggest me how to show pagenumber in footer section...Thankxxx in Advance

What version of IText? Older versions have the HeaderFooter object — Sean, Nov 04 '11 at 14:42
What is the output of your Phrase with writer.getPageNumber()? If it is blank, try adding some text around it to see if there may be other issues. that is the call to get the page number. you should be able to format accordingly around that — Sean, Nov 07 '11 at 16:14

Guys i have found the solution and chaged the class too.. here itzzz...

public class HeaderAndFooter extends PdfPageEventHelper {

public void onEndPage (PdfWriter writer, Document document) {
    Rectangle rect = writer.getBoxSize("art");
    switch(writer.getPageNumber() % 2) {
    case 0:
        ColumnText.showTextAligned(writer.getDirectContent(),                            Element.ALIGN_RIGHT, new Phrase("even header"),
                rect.getBorderWidthRight(), rect.getBorderWidthTop(), 0);
        break;
    case 1:
        ColumnText.showTextAligned(writer.getDirectContent(),
                Element.ALIGN_CENTER, new Phrase(String.format("%d", writer.getPageNumber())),
                300f, 62f, 0);
        break;
    }

below code you have to give in your print class finally the byte stream expels out... there you have to give

baos = new ByteArrayOutputStream();
        Document document = new Document(PageSize.A4, 60, 60, 120, 80);
        PdfWriter writer = PdfWriter.getInstance(document, baos);
        HeaderAndFooter event = new HeaderAndFooter();
        writer.setPageEvent(event);
        document.open();

It works Fine and Simple for PageNumber generation.... Note: i have used iText 2.1.0.jar
