Hi Guzs,
I have a pdf form, that I can fill out. My only problem is, that I cannot
embed file in it at the end. The pdf is not generated if I try to embed.
I highlighted the problem in the code.
Could you help me out please? Thanks a lot!
Here is the source code:
import com.itextpdf.text.pdf.AcroFields;
import com.itextpdf.text.pdf.PdfName;
import com.itextpdf.text.pdf.PdfFileSpecification;
import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.PdfStamper;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.*;
public class formPdfServlet extends HttpServlet
{
/**
* Processes requests for both HTTP <code>GET</code> and
<code>POST</code> methods.
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
//get current system date with GetCurrentDate() call
protected String GetCurrentDate(){
Calendar cal = new GregorianCalendar();
int month = cal.get(Calendar.MONTH);
int year = cal.get(Calendar.YEAR);
int day = cal.get(Calendar.DAY_OF_MONTH);
String date = year + "." + (month+1) + "." + day;
return date;
}
protected void processRequest(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
try
{
// create simple doc and write to a ByteArrayOutputStream
ByteArrayOutputStream baos = new ByteArrayOutputStream();
String pdfFile = getServletContext().getRealPath(
"/includes/gaz.pdf" );
PdfReader reader = new PdfReader(pdfFile);
PdfStamper stamper = new PdfStamper(reader, baos);
AcroFields form = stamper.getAcroFields();
form.setField("kelt", GetCurrentDate());
form.setField("3", "3");
form.setField("4", new
String("ÖÜÓŐÚÉÁŰöüóőúéáű".getBytes("8859_2")));
stamper.addFileAttachment("/includes/ips.xml", null);
stamper.setFormFlattening(true);
stamper.close();
// setting some response headers
response.setHeader("Expires", "0");
response.setHeader("Cache-Control", "must-revalidate,
post-check=0, pre-check=0");
response.setHeader("Pragma", "public");
// setting the content type
response.setContentType("application/pdf");
// the contentlength is needed for MSIE!!!
response.setContentLength(baos.size());
// write ByteArrayOutputStream to the ServletOutputStream
ServletOutputStream out = response.getOutputStream();
baos.writeTo(out);
out.flush();
}
catch (Exception e2)
{
System.out.println("Error in " + getClass().getName() + "\n" +
e2);
}
}
