I did it again, Header, footer and image in itext!
Hello, for those who are interested in adding a header and footer in a pdf file using itext, the solution i found its quite simple, just add this servlet to your project like any other but dont make aservlet call to it:
/*

head.writeSelectedRows(0, -1, document.leftMargin(), page.height() - document.topMargin() + head.getTotalHeight(),
writer.getDirectContent());
PdfPTable foot = new PdfPTable(1);
PdfPCell cell = new PdfPCell("This place is to wirte your footer text "));
cell.setHorizontalAlignment(Element.ALIGN_CENTER);

throw new ExceptionConverter(e);
}
}
}
After doing the servlet, in your original pdf in where u generate the report u want, just add this line code to call it:
writer.setPageEvent(new EndPage());
where EndPage is the name of the java class for the file, after doing this if u want to add an image to the header or footer just chage a part of code like this:
PdfPTable foot = new PdfPTable(1);
Image jpg = Image.getInstance("logo.jpg");
jpg.setAlignment(Image.RIGHT);
jpg.scaleAbsolute(100, 30);
PdfPCell cell = new PdfPCell("This place is to wirte your footer text "));
cell.setHorizontalAlignment(Element.ALIGN_CENTER);
cell.setBorder(0);
for (int k = 1; k <= 1; ++k)
foot.addCell(cell);
foot.addCell(jpg);
foot.addCell("This place is to write your footer text ");
foot.setTotalWidth(page.width() - document.leftMargin() - document.rightMargin());
foot.writeSelectedRows(0, -1, document.leftMargin(), document.bottomMargin(),
writer.getDirectContent());
If u have any doubts, just post again, and i hope this helps!
