Hey Guys,
I'm trying to create a Dynamic Header in the pdf page based on the user
whose data is being displayed on the pdf page. But for some reasons header
displays the data for last user only on each page.
That means onEndPage is getting fired at the end of the document and not at
the end of each page.
I've modified one of the example from iText in Action book to display how
I'm trying to setup the header.
Here is the Example.
import java.awt.Color;
import java.io.FileOutputStream;
import java.io.IOException;
import com.lowagie.text.pdf.BaseFont;
import com.lowagie.text.Rectangle;
import com.lowagie.text.Document;
import com.lowagie.text.pdf.PdfPageEventHelper;
import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.Element;
import com.lowagie.text.Font;
import com.lowagie.text.FontFactory;
import com.lowagie.text.PageSize;
import com.lowagie.text.Phrase;
import com.lowagie.text.pdf.PdfPCell;
import com.lowagie.text.pdf.PdfPTable;
import com.lowagie.text.pdf.PdfWriter;
/**
